Removing redirect link malware
I have Xiaomi Mi3 and it's not rooted. Every time I open a web page, both on mobile data and WiFi, and even with different browsers, I get redirected to other pages with ads and pages like this:
http://mobiles.digital/IT/Sweepstake/LP/index.php?voluumdata=vid..00000004-4837-403c-8000-000000000000__vpid..ca8d4800-fd5d-11e4-88ba-7eef5f3eb726__caid..5422e033-3dc6-4996-b128-7bf07d491d19__rt..R__lid..19777e53-9ce2-45a2-8073-ce9466d65506__oid1..7756b6f2-77b0-4db4-8d79-0faa4854c67f__oid2..b504e00f-54b7-4fd2-99de-09a0e4919980__var1..425682__rd..www%5C.%5Cyouradexchange%5C.%5Ccom&SiteID=425682

I have tried:

Many antivirus (including AVG premium app which was free this weekend on Amazon app shop)
Factory reset: inside settings on my phone
Hard reset: deleted cache and installed app.
AdBlocker plus.

But nothing worked.
Here's the installed apps on my phone: https://drive.google.com/folderview?id=0B2cFQ2PnOtfNT0NsMnZJY1NiT1U&usp=sharing

Is your phone rooted? 2) Have you tried an adblocker? 3) Can you share screenshots of the apps installed (if no privacy concern exists)? 4) Does it happen on Wifi , mobile data, or both?

1)No 2)Yes, ive tried adblock but 3) i'll share it asap 4) both thanks for good question gonna edit my post asap

Are you going to share screenshots (mentioned in the comment)?

For me the album link don't work even logged into google plus. Are you sure it's public?

@FedericoPonzi I agree with user3344236. The permission to view the album by others isn't granted yet; Please change it to public.

It seems you're infected with YourAdExchange malware (note the URL at the end). However, I still haven't found any clue to clean it on Android.

Andrew T. this can be a false assumption also. I think the correct title should be: removing redirect link malware on Android phone. :)

@user3344236 fair enough since I couldn't find any clue related to that malware on Android.

Recently there's a similar issue related to YourAdExchange. I'm not really sure if your case is the same as that, but you might be interested to try the answer before flashing the ROM.

I'd like to get more information to help. Could you show the MIUI version of your phone? See it in Settings -> About Phone -> MIUI version. If you can use adb in your PC? I think It will be helpful if you can show the output of PC command "adb shell pm list packages" and the output of "adb shell ls -l /system/app /system/priv-app"
By the way, if a factory reset can not resolve the problem you can try a full ota update which will reformat the system partition. To do full ota update: Click the Updater app, and then click the menu button in the right top, then click the "Download update" item. !Remember to backup your files!

The MIUI version is 4.10.17,  android version 4.4.4 . When i try to Download update i get a "no update available "message, so i can't do it. Thanks anyway!

4.10.17 is a beta version and is rooted by default. Did you get it from the MIUI's official website? (en.miui.com)

I actually brought it from xiaomi on Amazon

I think you can try to download a full ROM package to do an update and then do a factory reset. The official download website: http://en.miui.com/download.html

Try Avast free  and Malwarebytes , one after another (not 2 installed in the same time).
Try to move the app masked as com.securitycore.miui_t to SD card, then scan your phone again.
Reasoning:
I removed an "insane" pop-up linker (no matter what browser I used) which, instead acting like an activity by default (a malware activity) just used text displayed on webpage ( reading html meta tags ) and added link with advertorial content (manipulating content by adding div contents) or opening random links even if I visited “legit” and “clean” sites.
I recommended Avast for it's heuristic engine (IMHO better than AVG). Malware bytes actually marks threats and help remove some “non-detectable” adware (details about heuristic engine vs. databases containing signatures of viral code is out of the scope here).
Having in fact an extended experience with those kind of threats, my advice is a first step for taking countermeasures against this malicious object (script). I also see the user has a strange object acting like overwriting content or redirecting page.
So, after scanning with those 2 tools, the user may come back telling: none worked. How we must interpret this second problem? I think the key in this case is thinking about “where” antivirus and other products used did not look. As obvious, there can be two major places: /data/ or /system root folders. So, in case we still have troubles after scanning with some tools the solution which comes to mind is to go in /data/ or /system folders and manually remove application which we suspect (browser application, in our case).
Being aware the user has a non-rooted device, a simple solution is to use another browser after deleting/uninstall browser app which caused trouble. I hope the user has original ROM by Xiaomi and not a "modified" one (there were rumors about malware packed inside 'Xioami' counterfeit rooms, even if the device looks legit).
Readings for reference:

[Android] Android malware found on Google Play with millions of downloads
Popular Xiaomi Phone Could Put Data at Risk

From the settings page of the app, i cant find move to sd options. Seems like Xiaomi dosen't support move to sd natively. http://en.miui.com/thread-12681-1-1.html

Try to disable/delete/uninstall com.securitycore.miui_t (do not reboot phone) and see if browser still acts strange. I think it should be enabled again on reboot. I doubt  Malware bytes and Avast did not find anything strange...

Can't disable/delete/unistall it! Removed the data but the adware is still there :(

Cannot enable USB mass storage (UMS) after changing internal SD card to emulated
After I changed internal SD card to emulated (previous was on it's own
partition) I cannot enable USB mass storage of internal card.
I got inspired by section "Emulated primary only (like Nexus 4)" in
https://source.android.com/devices/storage/config-example.html.
I'm trying to figure out what to change in vold.fstab to be able to enable USB mass storage.
I'm working on Allwinner A31s, on Android 4.2.2 Jelly Bean.
vold.fstab before my changes was (internal card was /mnt/sdcard):
dev_mount   sdcard  /mnt/sdcard auto    /devices/virtual/block/nandk
dev_mount   extsd   /mnt/extsd  auto    /devices/platform/sunxi-mmc.1/mmc_host  /devices/platform/sunxi-mmc.0/mmc_host
dev_mount   usbhost1    /mnt/usbhost1   auto    /devices/platform/sw-ehci.1 /devices/platform/sw_hcd_host0  /devices/platform/sw-ehci.2 /devices/platform/sw-ohci.1 /devices/platform/sw-ohci.2

I removed the first line (for /mnt/sdcard). I also tried to add line:
dev_mount   sdcard  /mnt/shell/emulated     auto    /devices/platform/sw-ehci.1 /devices/platform/sw_hcd_host0  /devices/platform/sw-ehci.2 /devices/platform/sw-ohci.1 /devices/platform/sw-ohci.2

but it didn't help.
I suppose it needs to be entry in vold.fstab for emulated devices as well. How to find correct sysfs_path?
I also changed attribute android:emulated to true in storage_list.xml.
UPDATE: The change in partition layout was to remove partition for internal SD card (/mnt/sdcard) and resize /data partition – add this free space to it. Internal SD card is mounted into /data partition (as /mnt/shell/emulated in /data/media).
It's done with sdcard service (defined in rc script):
service sdcard /system/bin/sdcard /data/media /mnt/shell/emulated 1023 1023
    class late_start

I have probably some misconfiguration in storage_list.xml as UsbStorageActivity is shown, but after clicking to enable button does not finish enabling. But this is a minor problem, the main issue is the inability to set UMS.
When I watch vold with vdc   monitor it does nothing, prior to previous version when it worked as   expected - unmounting device and changing it's state). This happens also if  there is also external SD card presented.
Debugging with logcat shows that in case of emulated SD card:

PackageManager is not called
Vold is not called
MediaScannerReceiver is not called
MountService (runned in thread by UsbStorageActivity) skips both   internal  and partition (doesn't umount either of them) and progress indicator keeps running.

You can't. UMS only works on complete partitions, which are "physically handed-out". So if I understood your question correctly, and your "emulated card" now is just "a subdirectory of some other storage" (and no longer a separate partition – your question is lacking those details), AFAIK there's no way to use it with UMS.

@izzy: Thanks for info. Could you provide link to documentation? Is it version dependent, or is it valid for all android versions (>= Jelly Bean)? What surprises me is that Nexus 4 (mako) should have internal card emulated (not on physical device) and it's possible to share it to computer (as MTP or PTP) – see init.mako.rc for Jelly Bean. The main purpose is to connect internal storage anyhow to computer.

All depends on setup. The "emulated" variant is using FUSE. You can of course set this on top of a "full partition" (which might be the case with the N4), and then of course can make that available via UMS as well. Doesn't depend on Android version, but rather on whether the underlying "card" is on a separate partition or not. But no, I have no link to documentation – just "general knowledge" :)

How can I install an app directly on my SD card?
I would like to install a 4.0Go app but my internal memory only has less than 1.0Go free. However, my SD card has 32.0Go free space. How do i install the app? I have a Motorola 2G

You can try using adb install -s your.apk

@user3344236 I doubt that would work, as adb install in the first step needs to copy the .apk to the device – where it usually is (temporarily) placed in internal storage. Whether there's a possibility at all also depends on how much of the app in question can be moved to SD card (remember that with App2SD, parts of the app always remain in internal storage). If that fits, there's a small chance to adb push your.apk /sdcard/your.apk && adb shell "pm install /sdcard/your.apk" – though I'm not entirely sure if that wouldn't trigger the same issue.

http://www.makeuseof.com/answers/how-can-i-directly-install-apps-to-my-phones-sd-card-from-the-google-play-store/   and http://www.fixedbyvonnie.com/2014/06/install-android-apps-sd-card-default/

This is only allowable with certain apps, on a per app basis. if the app doesn't allow it, you can't move it to run/work on an external SD card.

How can I backup and restore Google Now Launcher home-screen layouts?
The only times I've seen a successful restore of the Google Now Launcher home-screen layout is when it is the default launcher from the onset as the installer goes through it's motions.
Restoring a backup from Titanium Backup does not work.
I've also tried making a recovery flashable update.zip via Titanium Backup but it still won't restore the home-screen layout

Have you tried with adb backup resp. adb restore?

Try backing up the entire Google app, not just the Google Now Launcher as it does not store any data itself.
Backing up the Google app (and you can try the Google Now Launcher) in addition to it, should work.

How do I disable the drop-down spell check box?
I just updated my Galaxy S4 to Android 5.0.1/Lollipop. I don't like to use the drop-down spell check/autocorrect box; I prefer the one built into the Google Keyboard that displays as a line of suggestions above the keyboard. The drop-down displays over that line so I have to back out of it to tap a suggestion.
I had it disabled on Android 4.4.2/Kitkat and cannot figure out how to turn it off in 5. I've toggled all settings under Google Keyboard and Samsung keyboard to no avail. The only way I could find to disable it was to force close the Samsung keyboard, but unfortunately I can't permanently disable it.
Thanks!
Screenshot:

I've given up and will just live with it...I don't think this option can be turned off in Android 5.

I managed how to disable the Lollipop's spell checker, (not one from keyboards as in other answers).
Just go to, Settings → Language & input → Spell checker then switch it off.
Already done ;)

On the Galaxy A 5, go to : Settings -> Language and Input -> Samsung Keyboard Settings -> and switch "Predictive text" to off.

Check if you have Google Keyboard installed in Play Store. This keyboard somehow done all the spell checking despite the fact that I couldn't find it in settings, I wasn't even aware I had it installed. After uninstalling Google Keyboard spell checking turned off.
(not my advice, I checked it on http://forums.androidcentral.com/samsung-galaxy-s5/514492-spell-check-won-t-turn-off.html)

Well, it did turn off spell checking (the red underlines) but not the drop-down. Thanks!

To disable spell check you just need to disable Google Keyboard (GBoard - Google Keyboard). It works if you use different keyboard, for instance, SwiftKey (as I do actually).

The drop down bugged me for ages too as I would go to tap the correct word along the top of the keyboard and the drop down overlay would always pop up in the way and I would hit the wrong thing.
Here's how I solved it:
Settings > Language & Input > Google Keyboard (It was the 2nd option under Keyboard & Input Methods for me) > Gesture Typing > switch off Dynamic Floating Preview.

Samsung Note 4: Go to Settings → Controls→ Language and input, and make sure that default is set to Samsung Keyboard.
Under that, tap on Samsung Keyboard to open it. Scroll down, tap Predictive text to open, and move the slider (in the top right corner) to off.
Done.

Unfortunately I've come to the conclusion that, at least in Android 5 on my Galaxy S4, there is no way to disable the spell checker. I've been trying to just adjust my correction method to use the drop-down.

I want to root my tablet but cannot
I have a samsung tablet that is entitled samsung tab 4 t-351. I wish to root it, but can find nothing. I have tried towelroot, framaroot, one click,root master, king root , vroot,iroot, and poot

Try searching for your specific device's root, like "root galaxy tab 4". There certainly are guides on how to do it.

The model you specified (T351) doesn't seem to exist, so I am just going to assume you have the T531.
A quick Google search for samsung galaxy tab 4 root t531 yields an XDA page of someone wanting to root the same model as yours and has had success with CF-Auto-Root.
Worth a try, since Chainfire's works are pretty much dependable.

Widget to toggle "OK Google" detection always on/off
I am looking for a widget which toggles my Nexus 6's option for "OK Google" always listen on/off.
Usually when I am in the car, I need the phone to always listen for "OK Google" and easily turn it on before I get there. After I leave the car, I need to turn it off, because it detects random sounds as the command and never stops listening for noise sounds.
I think such widget does not exists and I do not know if Android exposes API calls for this. I am web developer and I am willing to try to code this widget myself (never tried to code for Android), but I have the will if someone points me to the right direction.
Thanks!

you might wanna look into this https://play.google.com/store/apps/details?id=com.RSen.Commandr&hl=en

It's cool indeed, but not really what I am looking for. Thanks!

in the above link , there you can find the github repo link where you can find the source code of that project where you can start building your app based on that but before that you need to learn and create basic android apps before directly coding the app you want.

Tasker might be able to do what you're asking.

Tasker doesn't seem to have this functionality

It's not the best method but if you happen to use Nova Launcher you can make a widget that gets to the Voice Command Preferences (which is just one click away from accessing the detection settings).

Long-press on the home screen (with Nova installed)
Click Widgets
Place an Activities shortcut somewhere on your homescreen.
Scroll down to the Google App
Choose com.google.android.voicesearch.VoiceSearchPreferences

and you'll at least have a widget that gets you right to the Voice Search Preferences where you can then click on Ok Google detection.

Thank you for your suggestion, but I do not want to change the launcher. I want to use a widget which is independent of the launcher.

What Nick Ebi described for Nova launcher is also possible without switching to Nova (or Apex launcher, which offers the same). You can use Activity Launcher, an app working independently from the launcher you're using (in fact, it should work with any launcher). Launch that app, and then follow steps 4+5 of Nick's answer, and you will end up with a shortcut on your homescreen. Activity Launcher even allows you to edit that shortcut, giving it a custom name and even assign it an icon of your choice.
Again, not a full solution – but an improvement at least.
For a full solution, follow ND Geek's advice from the comments on your question, and use tasker. While Tasker itself might not have this functionality, there's the AutoVoice plugin offering you an "always listening" mode (called "continuous" there). But that doesn't come for free: both have a trial version, though.

com.google.android.voicesearch.VoiceSearchPreferences is opening the first settings screen. Then I have to click "Ok Google detection" and switch the "Always on" setting. I am looking for direct toggle of this setting. So far this is the closest answer to the solution :)

@IvanDokov, have you checked the second half of my answer? AutoVoice can do that. I've ended up with a widget to toggle "Continuous Mode" on/off. Isn't that what you've asked for? Check out my collection of Tasker resources, which a.o. also holds a section with "AutoVoice Tutorials".

To be honest the first time I tried Tasker I got lost and didn't like it. I will try again today :)

@IvanDokov To be honest, it took me 3 days to figure how it works when I tried it the first time – but on that 3rd day, though I had 4 days of trial left, I immediately bought the license as it really convinced me. Yeah, it might have a steep learning curve – but it's worth it!

I don't believe there is a widget, but you can turn it on/off in the google app under the ok google settings.

I am aware of this, but I want to use widget for faster usage.

Downloaded mp3 only plays for about 2 minutes. Is there a setting I have to change?
I've downloaded several mp3's so I can listen to them on my Samsung Galaxy S3. When I play them either through Google Play Music or Sound Player, I hear about 2 minutes of audio then it stops playing. I've attempted this with multiple mp3's. Is there a setting I need to change?

What do you mean "stops playing"? Does the app close without notice? Force close? MP3 file gets deleted suddenly?

Does this happen if you put the device to sleep? I had a similar issue but related to sleep and music player

@aureljared The app does not close. It appears that after a few minutes of playing, the scroll bar that tells you how much time is left scrolls all the way to the end.

@Firelord It may happen when the device locks.

Whatsapp notifications
I recently updated my samsung note 4 to the latest android version 5.0.1, and since then my whatsapp notification always vibrates even if I turn off the vibrations in the app settings.
If the phone is on mute or ringer then it is fine.
Before the update it was fine even if the phone was on vibrate whatsapp didn't vibrate.
Anything I can do to fix this?

"I turn off the vibrations it still vibrates" Where did you turn off the vibration setting?

By default the setting is vibrate. If you want to change go to whatsapp setting ---> notification tab. Click notification there you will find vibrate default it has different options like "OFF,DEFAULT,SHORT,LONG" select which is suitable for you. Hope this helps.

It's off in the whatsapp settings.

Mani: The original question clearly states "...even if I turn off the vibrations in the app settings." Please ensure your suggestions are compatible with the specifics of the question asked.

Obtrusive notifications
If I'm playing a game or watching something in full screen, why does the notifications come over it? I've noticed especially whatsapp notifications fill up the screen.
I need to be able to only stop the heads up notifications when in game mode or full screen watching video, not totally turn it off. is there a way to do that?

Need some clarification: are you running on Lollipop? If it's, then it's the heads-up notification (new feature on Lollipop), if it's not, and only WhatsApp do that, then check the settings on your WhatsApp.

@AndrewT. yes it's loliipop.

Answer to first question: Because Google wanted a new notification system that was more visible and obvious, much the way iOS handles their notifications. A lot of defectors from iOS actually missed that.
Answer to second question: this is done on a per-app basis, for those that support it. Most apps don't even use the feature, but for those that do, some allow you to disable the pop-ups, or heads up notifications. But that's the only real way to do so without potentially disabling notifications in general.

Open Whatsapp and set the following for Message Notification and Group Notifications

Whatsapp-> Settings -> Notifications -> Popup Notifications -> None

Now you won't get the notification poped up when you are using some other applications. And all the popup nofications for individual and group notifications will be turned off.

What might be the problem? My TV, my HDMI cable or the nexus player?

What kind of TV is it? Are you plugged in directly to the TV, or through a receiver?

I have a philips 32' (32PFL6615D) and the HDMI cable is connect directly to the TV. I have already tried all the HDMI ports of the TV, all have the same problem.

Help how do i disable the status bar
I usually hand over my Samsung Note 3 to my kids to watch Netflix , videos and play games etc. I recently notice that my status bar will not take off, I looked at every settings option, and I can't find the option to turn it off. I would appreciate if someone can help me thank you.

Jose, it might help if you explicitly mention which Android version you're on. With 5.0+ you could e.g. "lock your kids in" by pinning the foreground app (so they can't get out of it). Not sure whether that also hides the status bar (cannot test, have no Lollipop yet).

Best way that use gravitybox to change status bar and icon on statusbar

If you are on Android Lollipop then as Izzy suggested, you can turn on the Screen Pinning to stay in a particular app and hide the status bar.
If not on Lollipop then third party launchers such as Apex and Nova allow you to do this only in the home screen and app drawer screen.
As in the feature section you can see that you can hide the status bar,

Hide elements as you want (persistent search bar, status bar, or even
  the dock)

But this only hides the status bar in Home screen and the status bar becomes active once you open a specific app. Instead the developer of the app should have implemented the immersive model to hide the status and action bar.
But as mentioned in your question most games will hide the status bar and videos played with fullscreen does hides the status bar.
UPDATE:
Use Power Toggles and in the toggle actions use the Immersive mode and start any app you want. The app will start with the status bar and the action bar(Back, Home and Recent buttons) hidden and you can switch back to normal mode by clicking the toggling Immersive mode or to quicky display the status bar swipe from the top of the screen twice to display any notifications.

PS: All in One Gestures also allows toggling immersive mode (and to define several other useful gestures) :)

Oh wow thank you , but it did not work , I recently checked my device version and it says " 5.0 " not sure if I mention , I have a galaxy note 3. Sorry about the little information I'm giving and thanks 4 helping an old man.

@JoseSanchez you are using Lollipop version..you can use the Screen Pinning option and it comes default in phone..so you don't need to install any app..you need to turn on the screen pinning feautre first to use it. turn it on in the settings-> security menu and in recent tabs you can see that you can pin the apps you want..then the back and home button wont work..to unpin an app you need to touch the back and recent keys simulatneously..i don't know why this will not work..have you tried the screen pinning or the power toggles app..both are working in my case and i'm also using the version 5.

Radio service using battery
I haven't used any type of radio services on my HTC one, not even Pandora or anything else because I just never listen to music outside of radio in my vehicle, but I have radio usage on my phone. What else could cause this service to be running?

Is it always running, or just 1-time event? Cellular network sometimes can be referred to radio cell.

It shows that every app that I have used or opened it is running whenever that app is used. For instance if I used Facebook it shows the fm radio running or words with friends, or internet. It runs on every app.

@AndrewT. already pointed to the right thing: "radio" doesn't necessarily refer to "fm radio". In battery usage, it rather refers to your "phone radio", i.e. the cellular service. If it would refer to fm radio, the corresponding app would be shown as consumer.

Battery stats always lists consumers. If the mentioned entry would refer to "fm radio", it had listed the corresponding app as consumer.
You must be aware that the term "radio" is ambiguous here. It stands as an abbreviation for "radio waves", which in fact are used by "fm radio" – but also for communications using the cellular network. The latter is what you're seeing references as "radio" in the battery stats on some devices. Different devices might use different terms here, so a screenshot helps identifying the "item" by its associated symbol/icon, see e.g. What is Cell standby and how can I keep it from eating my battery?
With that link, I've also named how other devices might refer to this ("cell standby"). If your symbol looks similar to the one shown in the screenshot there, that would confirm what I've written here (note that it might look a little different on your device, not only due to a different manufacturer – but also due to the fact the screenshot on the linked question was taken with Android 2.3 ;)

Data Usage Warning in ICS
I found these related questions on the same issue:

How do I disable the data usage warning and notification in ICS?
How to turn of Google Samsung Nexus Galaxy 3g/mobile data usage warning?

But, my problem is the graph doesn't show up the limit lines. How to disable the notification now?

Screenshots (click for larger variants)
When I try to set mobile data limit I'm getting the message from the second screenshot and it backs to the first image. It is not enabling.

I fixed it editing the netpolicy.xml file manually. Increased the warning limit to 4GB in 3 places as shown in the image and rebooted. Then the notification went-off:

Remount /system to make it writable (mount -o remount,rw /system)
Edit /system/netpolicy.xml file as root:

Remount /system read-only (mount -o remount,ro /system) or reboot the device

You have to check the set mobile data limit to show those lines. As seen in the image below:

Screenshot (click image for larger variant)

Check my edit on that

@Fasna have you also tried enabling the statistics (setting that switch to "On")? Just thinking aloud (it shouldn't be related, but who knows).

@Fasna I've never seen the bars missing. But there's a comparable issue on some LG devices, using the wrong interface for battery stats by default. I worked around that one using an "activity explorer" like the one built-in to "Apex Launcher", or the stand-alone Activity Launcher, exploring the "Settings" app for available "activities". You could try that, maybe there's an "alternative activity" hidden where the bars are enabled. No guarantees, however.

No charger connected but showing as phone is charging
Moto G 2nd Gen phone is not working properly with android lollipop. Sometime the charger is not connected but it is showing the phone is charging. Even if I use headphone the music comes out from the loudspeaker.

Sometime the charger is not connected but it is showing the phone is
  charging.

A restart would fix this problem. I had this problem just after updating to LP and I never got after a restart. It's probably a small bug.

If I use head phone also the music comes out from the loudspeaker.

You need to change your headphones. Bad earphones are the cause of this issue. I had a cheap quality headset then I faced the same problem and upgraded to a quality headphone like sennheiser or skullcandy. Even the headphones which comes in the package is not so good. I personally use mi headphones which I found better than skullcandy in terms of sound and quality.

Application messages
Need assistance. If I power on or restart my GT-P7500 10.1 Samsung tablet, it takes an awe full long time to become usable. It keeps coming up with messages like "Messager is not responding" - with pop up to "close or report or wait choice". This carries on for a while with pop ups for various apps before it becomes stable and usable. Even then occasionally a pop up still appears.
I have cleared no of apps so that only half of the 32Gig Mem (stil got 11.7 Gig free). Running
Any help will be appreciated as this is very frustrating

First thing I'd try would be clearing all caches (which can be done by booting into recovery mode and select "wipe cache"). Sometimes "broken cache files" cause issues like that.

some unwanted applications will be restarting in the background causing to slow down..https://support.google.com/android-one/answer/4582729?hl=en

the messages will be downloaded instantly and  stored in your phone's internal memory and not in the whatsapp server so unless you dont factory reset or delete whatsapp data in your phone it will be available to you always..

According to my knowledge the message will be there for 30 days.Please refer the article attached in the link.

SMS with alphanumeric sender discarded
I am working in a company where we host a server to send SMS to mobile phone providers. We have several customers each day who cannot receive SMS we deliver to them because their Android SMS app discards them due to an alphanumeric sender. So, we have the "Delivered to Phone" state from the SMSC, but the customer effectively does not see the message.
We manage lists of customers who need plain numeric senders and circumvent the problem in this way.
Is there a way that might be a possible solution for - at least a good number of - the customers to easily setup their app or phone to accept/allow alphanumeric senders so we can tell them? Note, however that our customers are any average mobile phone customers, not necessarily with any informatic knowledge.

Ok, I give the answer myself. If you find out how to activate it (which is quite easy because the web is full of it), you also know how to deactivate it.
Sorry for the stupid question.

Getting message "Unknown id: netcfg" while setting up usb0 interface for reverse tethering
I am trying to setup reverse tethering between Sony Xperia 4.0.4(rooted) and Linux 12.04. I'm following steps from Matthew Read's answer on this post, How to set up reverse tethering over USB?
All steps work but when I execute "su netcfg usb0 dhcp" in root shell of phone then I get message "Unknown id: netcfg".

130|root@android:/ # su netcfg usb0 dhcp
  Unknown id: netcfg

I'm not sure what this message means and how to fix it. I could not find anything related in Google search. Can anyone please guide me about it.

Matthew's answer is from 2011, so it's definitely pre-ICS. My guess is that the netcfg command was renamed/removed meanwhile. Try replacing it by ifconfig (i.e. su ifconfig usb0 dhcp and see if that works (pointer taken from here). In the worst case, that might throw another error message. You could also check whether there's a similarly named executable (e.g. by typing net followed by a "", if your terminal/keyboard supports that – or by walking through the /system/bin, /system/xbin etc. directories).

I tried ifconfig but same result.

Urgs. My bad. You've got an error in your command, try su -c "netcfg usb0 dhcp" (first non-option parameter to su is the user to switch to; with -c you rather advice it to execute the command).

@Izzy, thanks! It fixed the error. You can add it as answer.

Thanks for your feedback! Answer posted. I will now also update Matthew's answer accordingly.

There's a slight syntax error in your statement: the first non-option parameter to su (which stands for "Switch User") is the user to switch to (if omitted, root is assumed). So your su netcfg usb0 dhcp basically advises su to "switch to the user netcfg – but there is no such user.
To fix it up, just use su -c "netcfg usb0 dhcp" – which would, due to the non-existent "first non-option argument", would advise su to switch to root and then, by the -c parameter, execute the Command netcfg usb0 dhcp. Further note the command is quoted: this is required as it contains (white) spaces.

How to flash Stock Recovery without PC
I'm trying to get back to stock recovery. Currently I don't have access to a PC. A few days ago, when I tried flashing the recovery.tar file via Odin, it failed. How can I get back to stock recovery? I have the recovery file in both formats i.e. .img and .tar.
Any help will be appreciated.
My Device : Galaxy Tab 4 SM-T531 Android 4.4.3 Stock

By "don't have a PC" do you literally mean you don't have access to a desktop or laptop computer, or do you mean you're using a Mac?

Provided that your device is rooted, you can use various apps to flash recovery without PC. Notable ones are Flashify and Rashr

@NDGeek I don't have access to a PC at the moment.

@Firelord I tried flashify but It didn't worked. After flashing with flashify when I reboot it boots into download mode saying couldn't do normal boot.

You can also use mobile Odin for this purpose. Look on play store ;)

Oooo also download pem it generates passwors for when you extract the tar file in mobile odin other way is twerp flashing it

Flashing Gapps on Second Account
I have a rooted Nexus 5 running CyanogenMod 12.1-20150510-NIGHTLY-hammerhead. I created a new user from the top right corner, but it didn't have gapps installed on it. When I try to install, it only replaces the one on the original account. How do I install it on the second account? I have TWRP Recovery

It should've been installed by default. If it hasn't then there is something wrong, do you see the play store if so go to the play store and install the other Gapps.
I think it's because you need to setup the space seperately. So you need to install it from there.

my android phone keeps asking “Sign-in to WiFi network” even if WPA/WPA2 is already authenticated
I'm trying to connect to a DLink Router protected with WPA/WPA2. It's our home router and I can connect perfectly to it from laptops and desktops, Linux and Windows alike, even for my friends mobile(Android) it connect smoothly. But when I connect to it using my Android phone (Motorola Droid), I am always notified to "Sign-in to WiFi Network" after I've entered the WPA/WPA2 password. Tapping into the notification loads my ACT logging page, and after entering my credentials it says you are now logged in, but when I try to open any other site or even refresh this page it again ask me for my ACT credentials. Other apps that connect to the internet do report connection problems.
I checked my router setting, in which I have added my mobiles MAC address also in Interface setup->wireless->wireless MAC address filters, but it is not working.
I have made encapsulation ISP as PPPoE and have entered my password there.
Still not able to connect in my phone.
I am able to connect my phone in all in my friends place so for sure thire is no problem with my phone. what else is required..?

On your Android device you go to Settings › WiFi, and long-tap on your AP's entry, selet to edit it, tick the "advanced" check-box, and verify the settings there: is it using DHCP, or a fixed address? In the latter case, does it match with your network, and has the correct gateway set? In the former case (DHCP), can you verify your IP/gateway (IP e.g. via Settings › About phone › Status) and see if it matches? Also, having the IP address: can you ping that from your computer?

Have you tried setting the ACT login as a proxy server?

I fixed mine by putting a static IP. I chose a IP in my network range and it work

Samsung s4 stuck on logo
Yesterday I installed the newest software update for the Samsung galaxy S4(GT-19505). At first, the phone was stuck on a loop of the update 'installing' to 100%, turning on then switching off and repeating. I did a battery pull and removed my SD card. when i went to switch on my phone and it was stuck on 'android is updating. i left it and fell asleep. this morning i switched it on and it started as normal but then froze and got stuck at the glowing 'SAMSUNG' logo. i have tried using the power+up+home to and cleared the cache partition but that did not help. i have also taken out and replaced the battery many times. Samsung Kies also does not recognise my phone. How do I fix this problem? I am a complete newbie when it comes to phones and the technical side of them and would prefer an easy guide as to how to fix my problem/what the problem is.I did a factory reset and wiped all my data with no result.please help.

is your phone rooted?

Hard Reset your phone.. But all your data and apps will be gone..
Turn off the phone. Press and hold at the same time Volume UP,Home and Power keys. When you see Galaxy logo release the Powerstrong text key but continue to hold the Volume Up key and the Home key.
Release them when the Android System Recovery screen appears. Use Volume Up/Down keys for navigation and Power On key for OK. Choose "wipe cache partition", "Yes -- delete all user data", "reboot system now".
And click on Wipe Data/Factory Reset
You are done then.

Small hint, though: What you describe is a factory-reset. A hard-reset would be "removing the battery and put it back in" ;) Then, the concluding sentence in the question is: "I did a factory reset and wiped all my data with no result." So what you describe was already tried without luck it seems (yeah, that ugly small-print always ;).

Oh yeah sorry.. I should have said FACTORY RESET

;) That was the "smaller part" (those terms are often confused, so you don't need feel bad for it ;). The bigger one was that the OP already did that, according to the question post – so your answer is unlikely to be of any help to Peter, unfortunately.

Then, I think he should download the Stock Rom for his mobile n flash it using Odin

Yepp, that would be my guess as well – a "fresh flash" might solve it. Maybe you [edit] your answer accordingly, and we clean-up (remove) our comments then? Don't forget a pointer on where to get that ROM (if you have it – if not, check the "hot" questions on the rom tag, first link on that page ;)

Yeah.. K.. Just wait

This doesn't help. OP already wrote in the first revision: "I did a factory reset and wiped all my data with no result".

Lollipop + Google Play - small application installs take 10 or more minutes?
The specs:

Samsung Galaxy S5
Android 5.0 Lollipop (new device, came with it)

Installing small applications in Google Play Store take 3-15 minutes, Spotify has been "installing" for over an hour. It's not the Wifi speed, because speedtest on the device showed 20-30mbit/s download, and my other Android 4 device installs the same application within a few seconds.
Any ideas? Are Google Play application installs fast on your Android 5 devices?
I tried removing the SD card, didn't help.

Andrew it might be because you have low internal/phone memory..apps are not directly installed onto SD card..so that's irrelevant and won't help.

There's gigabytes of internal memory, and 500mb+ free RAM, so that's not it.

Well I managed to solve it, got the idea from here: Application stuck in "Installing..." stage in Market.
I went to Settings > Applications > Manage Applications.

Force stop the Google Play Store application
Uninstall updates for the Google Play Store application

It warned me that Google Play Store would be restored to its original state, I accepted.
After this, I launched Google Play Store and installing applications was lightning fast. :)

Menus become cutoff and show as "..."
Sometimes when I go to open a menu item, it cuts off the text and I see '...'. Here it is happening on QkSMS but it happens on other apps too. Is there a way to fix it?
Here is a picture of it happening. I have an Xperia Z3 on T-Mobile running 4.4.4.

Screenshot (click image for larger variant)

Which other apps do this? Does it happen anywhere else in QK?

It happens to all the menus in QKSMS. If I open and close them a few times, it begins to work but this is not for just QKSMS. It happens on other apps as well.
Edit: Are you Moez Bhatti? Creator of QKSMS?

Seems like it could be app-specific (or library-specific, if all affected apps are using the same app bar/overflow menu libraries).

How do I select the number of an incoming SMS?
I received some SMSes that show up both in my SMS app and in Google Hangouts; however for the life of me I can't figure out how to just copy that number (in order to report it as a spammer), short of either adding it to my contacts (I don't want to) or writing it down on a piece of paper and re-entering it (which seems just plain silly).
Googling around, it seems there are quite a few SMS/MMS applications in the wild and I can't tell which one exactly mine is (it says "Version 4.1.1", but I can't find an ID), but I would expect either it or google hangouts to have that functionality somewhere ... so what am I missing?
(the obvious things - long press, short press, double click etc. on the number do nothing, and the menus only show me options for blocking the sender or adding it to my contacts)

Hint: For identification of the SMS app you're using, it might help to name your device and Android version, plus adding a screenshot (the latter especially when that app didn't come pre-installed).

In Google Hangouts, if I click the contact bubble (the circle on the right where their picture would be) it brings up their contact card. If you long-click the number there, there's an option to copy it to the clipboard.
NOTE: you may need to add the number as a contact to view the number in the "contact card."

Yep, that worked, and I didn't need to add the number as a contact. Thanks a lot!

How to stop my Android device from being spammed in the browser as well as in the application?
Recently I have downloaded two games:

Deer Hunter
PreHistoric Worm

But after that I have my browser which keeps redirecting me to http://ad.adsmatte.com
It is happening every time I load the page – after few seconds, it automatically gets redirected to this AdsMatte and doesn't go back to the previous page, even if I press the Back key.
In an application like WebMd, when I load the app, after few seconds it is covered with a full screen ad whereas it used to display the options menu. This is blocking my view and I cannot see what is being displayed by the application.

The WebMd app which is showing an "Update Your Browser" message with a "Install Now" link to Play Store (click image for larger variant)
I don't have Opera and it still tells me to update my Opera browser.
I closed the application and retried it, and again it is displayed with some "Warning your HM1S is affected with Virus" and starts vibrating.
Note: Please avoid anything like this post suits well on MIUI/forum, I have already asked there and got a very immature answer as to disable Java Scripts even after seeing my below screenshot.
[Update]
I have tried using mobile data and now it does not redirect so it's more of the modern problem the app are clean

which browser do you use..opera or chrome or something else?

It is UC Browser with Ad Blocker,Pop blocker enabled

your device may not have been affected by any kind of virus. i have used UC browser and it suggested to download unwanted apps and alerts like these..so i suggest you use chrome or opera browser..the redirection problem might be due to an extension(add-on) you have installed diable or remove all your addons and reset the browser settings..

For a starter, please take a look at our malware tag-wiki and follow the first-aid links. As you already described the issue started after installing those apps: Have you tried to remove them? Did that help? And btw: where did you install those apps from? // @Lucky no such thing like a "virus" on Android ;) But malware indeed, yes. Which is why I've added the malware tag to the question.

Community bump prevention: this question was closed because the question seems to have been abandoned (OP hasn't visited the network for more than 4 years, and no answers have score above 0). If anyone can evaluate the existing answers, feel free to vote accordingly and reopen the question (or mod-flag the question requesting for reopening). For anyone else having the same issue, please post a new question and refer to this question as additional context.

Based from the same problem on AskUbuntu, this is not OS-dependent, but an attack to the router. Try hard reset the router.

This does not appear to be an OS related issue. I would recommend you to read this http://www.quora.com/How-do-I-stop-AdsMatte-spam-popups-and-ads
Basically it is an attack on/via your router. You should hard reset it. A lot of computers on my intranet got affected. I got rid of it that way.

If it still fails, from Security.SE, try checking & fixing the DNS address both on router and Android device.

If your router is affected and you're facing different issues on your devices (Android has no ads, computer does) may check/change your DNS settings on both devices and on the router.
I think your Android phone uses a different DNS server as your PC. Your PC probably uses your router as DNS Server (e.g. 196.168.1.1) and your Android uses a 3rd party DNS like Google (8.8.8.8, 4.4.4.4) or OpenDNS. For this behaviour check: this answer on Super User
To clean up your router, you may have a look at:
  this answer on Security.SE

To check DNS settings on Android:

Open Settings - Wi-Fi
Long-press the access point, select Modify network
Turn on Advanced options
Change IP settings to Static
Check/set the DNS 1 & DNS 2 to Google DNS (8.8.8.8 and 8.8.4.4) or other trusted DNS server.

Installation problem in yureka
I cannot click install when selected an app to install in yureka ?( Not in play store,selected through a file manager) I'm sure it is not a touch screen problem.

disable your screen filter and try installing your app again

This is caused by a security feature of Android, to stop third-party apps trying to overlay or hide the permissions information when an app is trying to be installed.
Apps such as Lux, Screen Filter or any other filter/overlay app will prevent you from being able to click the Install button as they are essentially just an overlay, on top of the "Package installer" dialogue screen.
If you disable or turn off the filter whilst installing an app you should be able to click the Install button again. Once clicked you can turn the app back on.

How to stop creepypasta.wikia from suddenly redirecting me on Android basic browser?
For the past few days I've been reading the creepypasta.wikia site on my new, virus-free Android phone. For the past couple of days when I'm reading a story, not clicking anything at all, the page changes to another page saying that I need to update Android at the Google store, or one of two other adverts I can't recall exactly. The page I'm on changes, this isn't a pop up or under so if I want to return to the creepypasta I was reading I have to click Back. How can I fix this?

This is called malvertising. As an user, your only option is to use an ad blocker like AdAway.

How can I set the Accelerometer Sensor Range?
The Accelerometer Sensor is set to a Range of 2 - 4 g on most devices.
There is no option to turn it up to 8 or 16 G, which my sensor and most others are capable of.
I found some information but can't get any further how to achieve this.
I have the LIS3DSH Sensor in my Xiaomi Device.
There is a manual which states that in the configuration .hal file you can set:
/* ACCELEROMETER SENSOR \*/
#define SENSOR_ACC_LABEL “LSM303DLHC 3-axis Accelerometer“
#define SENSOR_ACC_INCLUDE_FILE_NAME “lsm303dlhc.h“
#define SENSOR_DATANAME_ACCELEROMETER LSM303DLHC_ACC_DEV_NAME
#define ACCEL_DELAY_FILE_NAME “pollrate_ms“
#define ACCEL_ENABLE_FILE_NAME “enable_device”
#define ACCEL_RANGE_FILE_NAME “range”
#define ACCEL_MAX_RANGE 16*GRAVITY_EARTH
#define ACCEL_MAX_ODR 400
#define ACCEL_POWER_CONSUMPTION 0.033f
#define ACCEL_DEFAULT_FULLSCALE 4

But I have no idea how to do this.
Resources to read:

Hardware abstraction layer for Android
Android accelerometer full range

I would be really glad if someone knows the way to go, or point me in the right direction for further research.

Force an app to full-screen mode
Is it possible to force an app into full-screen mode so all the soft-keys will disappear and the app will take up the entire screen areas?

For rooted devices, you can disable them quite easily:

Open the File Manager App, then tap the Menu button (capacitative or onscreen), and tap Settings.
Go to General Settings, scroll down to and tap Access Mode
Switch to either "Prompt User Mode" or "Root Access Mode"
Open the sec_touchkey.kl file in ./system/usr/keylayout/
Put a # symbol before the both the following lines:
key 139 MENU VIRTUAL
key 158 BACK VIRTUAL

Close, saving changes
Reboot

Alternatively, if you don't want to root, then you can find apps that provide fullscreen/immersive mode on Play Store.

My Nexus 5 got stuck when connected to PC
I connected my Nexus 5 with PC and was transferring pictures. Suddenly it said the device is not working.  Since then my mobile is stuck.  I can't even power it off.  What should I do now?

You should still be able to hold down the power button on your N5 for several seconds to turn it off -- even if it's stuck.

Hold vol down + Power button for few seconds and the phone will reboot to bootloader then you will have choice to reboot anywhere you want

The phone won't go into bootloader by pressing buttons when the N5 is turned on.

Actually that's the only way to power off a freezed Nexus 5, try the both vol up and down + power.

Images have disappeared from gallery, but still in "My Files" (Samsung Galaxy S6 Edge, 5.0.2)
I have a Samsung Galaxy S6 Edge (64GB) running Android Lollipop 5.0.2 which I've had since release day (April 10th 2015) and as the title mentions, there seems to be an issue in that my images are no longer displaying in the default gallery app. I also have quite a lot of music on the phone which doesn't display in the "Music Player" anymore. I'm not sure what causes the photos and music to disappear as it seems to be totally random. I can still see the files in the default file manager "My Files".
The first time it happened I thought that it may have been a glitch so did a factory reset and everything was fine again (although it does take about 3 hours for me to get the phone just how I like it). It then happened a second time a few days later and so I did another factory reset. When it happened the third time I was getting pretty annoyed and took it to my local Samsung Repair Centre where they said it was a software problem and they would have to reinstall Android and it would be sorted. However, 5 days later it happened again so I went back to Carphone Warehouse where I purchased the contract from and demanded a new phone as it had to be an issue with the phone as I couldn't find a record of it happening to anyone else and Samsung had already eliminated a software problem.
NOW, 2 weeks after I got a new phone IT HAS HAPPENED AGAIN! The images were there this morning and come this evening they have all disappeared from the gallery and again the music has disappeared. I've done nothing out of the ordinary with my phone today so cannot identify what has happened.
If I take new pictures on the camera, they appear in the gallery fine, but the old ones do not. If I look in "My Files" I can see that the old images are in the exact same location as the new photo that I've just taken... It's almost like they are hidden from the gallery. If I install an app such as QuickPic all the images are displayed in there, both new and old however I cannot use this for sharing images to facebook etc so it's not ideal.
The same applies to the music files that I have. If I look in "My Files" I can see them but they do not appear in "Music Player" which means that all my alarm tones have been set back to their default tracks i.e. "Morning Flower".
The screenshots below shows all the images that are currently in the Camera folder where only the top one appears in the gallery and only the top one is in the Images Category in "My Files".

I've had a play around with all sorts of settings, cleared the cache partition, clicked "Show Hidden Files" in "My Files" and rebooted the phone several times but there still seems to be an issue. I've also deleted the "Media Data" from the "Media Storage App" which emptied my gallery but on reboot didn't do a rescan (or at least didn't get any results). As it's an S6 Edge there is no SD card so it shouldn't be an issue with mounting the disk (although it wouldn't make sense since the new files are in the same location as the old ones).
I've managed to find a couple of people with a similar issue on AE but they've not had a response see here and here.
Is there some sort of debug log that I can create and upload to somewhere? Could it be a specific combination of apps that I've got since there are minimal people with the same issue?
I'd be grateful for any ideas as it's driving me insane!
Thanks in advance,
Adam.
EDIT: I've linked up my phone to the computer and run adb logcat but the log is huge and I'm not sure what I'm looking for. The following error appears fairly frequently:

< 6>[18330.193843] [6:MediaScannerSer:22775] binder: 3874:22775
  transaction failed 29189, size 416-0

If there is a specific bit in the log that would be helpful, please let me know and I'll do my best to extract it.
EDIT 2: Is there a procedure that I can follow to create a bug report that I can then send to Google or Samsung?

possible duplicate of Force Media Update?

Not really... There is no external storage on the S6, my issue happens randomly and a reboot doesn't fix it...

SDrescan & co also work on "non-microSD card" phones, as the underlying mechanisms are transparent to the used file-system (in your case: /sdcard is made available through a fuse layer, which is part of Android since 4.0 to emulate the old FAT32 characteristics).

Seems indeed to be a Samsung software bug. Can you try to "delete data" of the Media Storage app (find it here: Settings=>Apps=>all apps=>"media storage"=>"delete data"). external howto here.

So I did the delete data thing and everything disappeared from the gallery... Did a reboot and still nothing is showing. Is there a way to manually refresh the gallery? All the apps  I've tried just crash straight away...

This should definitely not happen, seems to be a Samsung software bug. Alas remote help is not easy w/o more info. Could you provide logs? The tool in question is "adb logcat" which is part of the Android SDK (if you happen to run Linux, you can install only the android-tools-adb package that comes with your distribution). You can then provide logs when the SDrescan crash happened and maybe also why the gallery stays empty (which should automatically be repopulated).

Have you tried each of these: SD Card Rescan, Rescan SD Card!,  SD Scanner

I've tried all three of those apps (none crash!) But none of them make a difference. It does scan the files that need to appear but they don't appear. I'm running Windows but should be able to hook it up to an emulator in Titanium Appcelerator. I'll try later today.

It's not a problem of those 3 apps (you don't need to run them in an emulator), it's very probably a bug in Samsungs Android Firmware for the S6, alas. Hence my suggestion to install the Android SDK and use it to dump the logs using 'adb.exe logcat'... No idea what crashes the media scanner (it should rerun on it's own and repopulate the gallery).

@AdamHolmes have u tried it http://android.stackexchange.com/a/104857/27149 this and din't work for you..? and try using a app from playstore like Galleryics and Gallery Pro

@Lucky Using other gallery apps does display all the images, but it still means that I can't select images from apps such as Twitter / Facebook though as that uses the the main gallery app.

You could able to select which app to open to select those photos from the tw/fb apps..May be you have selected "Always" when selecting the options..clear the defaults for tw/fb apps and you will be able to selected from which app you want to list those albums and based on the app you installed you can select the photos from it and you wont rely on the default gallery app anymore..

Updated answer:
Check if you have a hidden file named .nomedia (double check also for uppercase name) on device memory (storage folder) and delete.
Go to Settings > Apps -> ALL -< Media Storage. Select Clear data + Clear defaults. Disable the App.
Reboot the device. Now enable again Settings > Apps -> ALL -< Media Storage. Wait a couple of minutes (so it should reindex files). I think all files should be now again in Gallery.
Note:  Do not try to run any rescan App, just follow the above steps.
Old answer:
The error you got in logcat is related to a specific function for processing/scaling up images. It is a known fact: Binder transaction buffer has limited and fixed memory (1MB). This buffer is used by all transactions and shared across process. For e.g., If you have a big number of large images files and some of them are corrupted  (either by poor, bad transfer via computer and device, computer and SD card, and so on), or some of them are not recognized by your app (in your case Gallery), once this app tries to create thumbnails or previews for your files and actually scale down/up one of those files, the process may fail.
The same case must be with a number of files (like ringtones or .wav diles, or .ogg, or any type of music) which have problems either in content, size, signature.
Because you said the problem comes back, I suspect this kind of strange behavior from your apps. I don't even think to a bug in kernel or something like this.
So, for your own safety:

Try to put back all those files on your pc;
Clear from SD card/phone memory;
Verify in PC for the 'bad' files, then put back 'correct' files in your device.

Take in consideration this fact also: a .gif, .jpg, .png or whatever kind of image you have, may be rendered as 'correct' in your computer or device, but actually may have 'bad' content (disrupted content). Remember, all operation related to process images inside your Android device are based on compress/decompress them  (for the most common operations) and those are made 'bit-by-bit' if I can say so. Forcing an app to render incorrect type or content (wrong height/width/file lenght) should outcast a TransactionTooLargeException (this is what MediaScanner throws in logcat).

As you suggested I copied all the images back to my PC, removed them from the phone and then copied a few files back. My Gallery is now totally empty and not displaying any images. I've run the rescan app again and also rebooted the device. Still empty.

I have updated my answer. Do not try to run any rescan app, just follow the steps.

It works for me also.
The problem is not specific to Samsung. I have a Motorola E2 and was having the same problem.
Do the steps above. First you will feel like it is not working. But wait for 5- 10 minutes for the reindexing to complete. Then your files will become visible.

Followed on updated answer and waited for more than 10 minutes but still not working. Lenovo K5+

Tried on 2017-09-16 Clear data and clear cache on Media Storage, Gallery, Music apps without disable them and then restart.
After restarted wait for few minutes and check on the music app, or gallery app, or settings > ring & vibrate > tone list for call, message, notification. If there is some list appears then it is currently working just wait for it.

This same thing has happened to me and I've only had my s6 Edge a little over a week. I went through each file in my files and device storage and deleted ".nomedia" files. All of my pictures are now back in the gallery.

Its media scanner most likely. Thing is, on modern android versions very few media scanner apps are there in play store (especially for lollipop) and hence most apps will either crash or simply not work. So best thing is you can only try some apps and see if they work using hit and trial (I personally dont use lollipop so cant test). For ex, try this app maybe?
On side note, you can also try kicking media scanner through adb->
adb shell am broadcast android.intent.action.MEDIA_MOUNTED

Another method to try out is go to settings and clear data and cache for your gallery app so it re-analyzes all media.

I will try the adb command when I get home. As for deleting the media cache it just deletes it but never regenerates!

Ok, try this too-> Delete the data and cache for gallery. Enter adb logcat but dont press enter yet (I mean dont start logging yet). Open gallery and as soon as you press on it start adb logcat, let it run for 5 secs. Maybe it will reveal something better....

Make a New folder for your Images/Music
Move all your Images/Music files to new folder
Delete the old empty folder

I know it is very low quality answer without description of how it works. But I've shared it because it worked for me on my mobile and I have faced this problem  once.

This have solved my problem. Thanks.
I just removed the file '.nomedia' from android root directory. All my files are back again on gallery apps.
I am pretty sure that this file was created after installing google photos.

Using .nomedia file is Android's native way of allowing users to exclude a directory from mapping the images inside it. You can see such file in Android folder as well.

I have had this issue for a long time and I just found something that works:

go to your file manager (i use Explorer, if it matters)
navigate to /sdcard
select every file and directory
CUT all of them and immediately paste them all back in the same place

Apparently, you need to touch the modification date, and I found this easier than writing a shell script or renaming all of the files. They should immediately be back in the gallery once you succeed. Note: if there is an issue during the move operation, you will probably have data loss. Use at your own risk.

My Gallery didn't show my SD card pictures anymore after Xperia update to 6.0.1.
After multiple reboot attempts and ejecting the SD card once I found that the Gallery App has the following under its settings: Help > Find and fix problems (paraphrased from my German version)
After running this, everything is OK again.
Note: Files were always visible in file browser, so I guess it was some media scanner issue.

Use media scanner apps(such as force media scanner) to initiate  media scan manually.

I've just tried both "force media scan" and "rescan media" which just crash as soon as I click start...

Set Open DNS in Android 5.0.1
Just updated my Oneplus One to Android 5.0.1, and I can't change the DNS when I select the "Static IP" option in Wi-Fi settings. Basically I can put the values in, there is just no way to press OK and accept the changes.
It was possible in Android 4.4.2. Has anyone bumped into this issue?

This is one silly issue in Lollipop update (CM12) for OnePlus. I'm assuming you're running Cyanogen OS 12, and I found (on Reddit) and tested this solution some time ago.
Unlike Kitkat, you can't change only the DNS in Wifi settings as "Save"/"OK" is always greyed out if you do, i.e. you need to provide every single detail which includes:

IP address
Gateway
Network prefix length
DNS 1
DNS 2

As soon as you fill the first four entries, the option will appear to save the settings.
A brief description of each field is given here.

Loading from External SD / Saving to ExtSD
I rooted my device, an Android off-brand tablet, and finally found a way to get all my files onto my 32gb SD card instead of the internal SD. However, it says my apps aren't installed now when I click on their icons. Also, new apps install to the internal SD and not the external, despite changing set-install-location to SD. (Tried to change the set-install-location to ExtSD but wouldn't do it.)
The whole point of  buying that SD card was because the space was so insufficient. It boasted 8gb of space plus a MicroSD jack, but I can only use half that space since it's partitioned, so I'm not going to be moving any of the apps back. There simply isn't space, and I'm not uninstalling apps I need/use often. I'm confident there's a workaround somehow. (Sorry, anything I'm finding on Google is people replying with "move it all back"  basically, and I'm getting annoyed.)
I was thinking either I could have Android just use the 32gb instead of it's own storage, and use the internal storage as "SD", i.e. swapping storage. I don't plan on ever removing the Micro SD, as I said, it was bought for this purpose. If that's not possible, maybe there's something I can do to tell Android, "Hey, all the apps are here"?
Thanks, this is endlessly frustrating!
PS: Using Android 4.4.2

How come my adb can't simulate a touchscreen tap?
I've read I can simulate a tap on my touchscreen by using adb but it doesn't work:
C:\>adb shell input touchscreen tap 1 1
Error: Unknown command: touchscreen
usage: input [text|keyevent]
       input text <string>
       input keyevent <event_code>

How come I can't send a tap to my device? I have the latest version of the SDK tools and the SDK platform tools. Android Debug Bridge version 1.0.32. Thanks

Open a terminal on your device and type input. What options does it show? Is your Android version beyond 4.4?

Your version of SDK tools has nothing to do with the parameters input can understand or execute. Input is a binary in Android OS which can be run independently without requiring any set of external tools such as ADB.
The reason you receive the error "Error: Unknown command: touchscreen" is because you're running an Android version earlier than Android 4.1.1. You would already notice that in the input usage you posted, the binary entertains only two parameters i.e. text and  keyevent.
In Android 4.0.x, the input command's usage remains the same as the one you posted. In fact, even Android 2.3.7 has the same input command's usage. (See com.android.commands.input.Input on GrepCode for comparison of command's usage between Android versions.)
It was Android 4.1.1 which introduced tap and swipe parameter with usage,
usage: input ...
       input text <string>
       input keyevent <key code number or name>
       input tap <x> <y>
       input swipe <x1> <y1> <x2> <y2>

See the source code for more.

Older versions of android don't have the tap feature of the input command. I have a 4.0 device which lacks it as well.

Can Google device manager turn location on automatically?
For battery saving purpose is there any way to google device manager turn location on when we need it (Like when I search "Find my phone")???

This feature is not implemented yet. You must have GPS turned on.

No, this is not possible at the moment, may be you could add this to feature request in the Google Product forums.

How to make unlocking the phone using the password perform a specfic function?
Okay so I was thinking about this, and I can't seem to get my head around how to do it, so your help will be micy appreciated.
Basically, I have an android phone and my password is a pin that I use to unlock it. My question is, how do I edit the code so that:

I can have two seperate passwords,
One of the passwords will have a specific function such as deleting an application, so for example

If input is 1234, unlock the phone and uninstall Facebook?
I'm pretty certain this is doable, but I am a programming novice which is why I'm asking the experts! Thanks in advance!

The Xposed module PIN/Pattern Shortcuts allows this behaviour. To use, you must:

Root your phone
Install Xposed Framework
Install PIN/Pattern Shortcuts module, enable from Xposed app and reboot

Sim toolkit is missing after upgrade os to Android 5.0.2
I've upgraded my OnePlus One to 5.0.2 (CyanogenMod), but the Sim Toolkit app is missing.
Can anyone help to solve this problem, because I need this feature for mobile banking?

Check whether if it is hidden from launcher.

What Network are you on?

This is how I found it out to work. Create a SIM-PIN in your settings, restart the phone with the PIN, and you will have the toolkit in your app browser.

Please use your SIM with this toolkit as a first SIM (SIM1). Otherwise PIN code popup might not pop up. In my case switching SIMs helped.

Disable disable option
Is it possible to disable the disable option for a system app?
For example, if I turned Google now launcher into a system app, the disable option is grayed out. However, if I do the same for Google keyboard, option to disable is still there. So is it possible to disable the disable option for an app?
Note: I have a  rooted Android lollipop device.

Any specifics on Why do you want to disable the disable option..? and how did you turn the Google now launcher to an system app?

@Lucky I want it to appear to be"system default" More of a personal preference than anything technical. Moved the apk to system/app. Please don't give answers like"that is not necessary." All I want to know is if it is possible to disable the disable button.

It is absolutely possible to disable "Disable" as well as "Force stop" option for a user/system app. E.g. AFwall+ has an option to become Device Administrator which makes it immune from both of the options. IDK how you can do it but I gave you a lead here.

@Lucky Other than the method Andre used, there are many apps in Play store that claims to make a user app into a system app. It's a common ordeal. :)

As I thought, it seems like making an app Device Admin is the most popular way of disabling the said options. It is risky but it is the way. See this question and this link. Unfortunately, both requires programming the app to use Device Admin API, which may or may not be your goal.

What I don't understand is how the Google Now launcher has the disable option grayed out, while Google Keyboard doesn't have disabled grayed out, even when they are both in the system/app directory. Not that I am developing an application of my own, but rather I want to make Google Keyboard Un-disable-able.

Increase size of ext2 beyond 1.5GB
I have a rooted LG-D520 (Optimus F3Q) running Android 4.1.2. The internal memory that came with the phone was so small that I installed an 8GB SD card. I formatted it using MiniTool Partition Wizard with 1.5GB of ext2 (the rest is FAT32). Using Link2SD I've moved many of my apps over to the ext2 partition.
I do not have a ton of apps (they just seem to keep getting bigger), yet I only have 5% space left on the ext2. My internal memory has 27% left (355MB), but I've had to delete a lot of stuff to make room. I'm only using a small portion of the 5.9GB FAT32 partition, so I'm wondering if...

I can increase the size of the ext2 beyond 1.5GB. Is there a maximum size and, if so, what is it? Can I repartition without losing my apps & data or do I need to backup, format and start over?
I can add another ext2 partition to my SD card and load apps into there. Can you have multiple ext2 partitions and, if so, would that work with Link2SD?
Are there any other options ?

This has been a frustrating endeavor and it's unbelievable the lengths you have to go to in order to do basic stuff on an Android phone, so I'd appreciate any advice.

Here's how I did it when I needed to increase the size of my second  (ext2) partition that Link2SD used for applications from 2GB to 6GB:

Use free version of Mini Partition (v9.1) to

a. shrink the first partition (FAT32) by 6GB
b. ensure the existing 2GB ext2 partition is at the end (so that the second space after the first partition is the now unallocated 6GB space)
c. create a new 6GB primary ext2 partition in the unallocated space

Use the free version of Paragon ext2fs to mount the 2 ext2 partitions in Windows and allocate each a driver letter
Use Windows explorer to copy the contents of the old 2GB ext2 partition to the new 6GB partition
Put the card back into your phone and have Link2SD recreate the mount scripts for the 'second partion' (just to make sure the 6GB one works)
Use Mini Partition to:

a. delete the old 2GB ext2 partition
b. move the 6GB ext2 partition to the end of the card/drive
c. extend the FAT32 partition to fill the 2GB unallocated space.

This looks really interesting. I'm excited to give it a try, however, I'm nervous about messing up my phone. So I'm going to buy a 2nd SD and then use Windows explorer to copy the contents from the old SD to the new SD. I'll let you know how it goes...

Brilliant! I only had an 8GB SD which I didn't want to touch (just in case) so I bought a 32GB SD (~$25) and followed the directions on http://www.noypigeeks.com/android/tutorial-a-guide-to-link2sd/ to set it up. Since I only have 1 SD slot in my laptop, getting the ext2 partition from the 8GB to the 32GB (allocated 10GB for ext2) was problematic. I solved it by using Mini Partition to copy the 8GB ext2 partition to a USB thumb drive. I then copied the USB ext2 to the 32GB ext2. Interestingly, I had a hard time with Paragon extfs copy across mem devices. Same device copy worked, however!

You can expand the ext2 partition easily as most partitioning tools such as the one you used to create the partition can handle this.
Edit: turns out resizing ext2 can not be done easily using Minitools or any other popular partitioning tool for Windows. If you really want to resize, you should probably use a Linux live disk or a Linux virtual machine to use the native Linux programs for resizing, like GParted.
Increasing the partition size for your ext2 partition basically means moving files on the FAT32 partition around to make a continuous free space, then shrinking the FAT32 partition then extending the ext2 partition to fill the empty space, and finally expanding the filesystem. Many tools will do all this for you if you just select "shrink" on the FAT32 partition and then "extend" on the ext2 partition.
This process should not cause you to lose any files or data, but you should probably back up the contents of your partitions before changing the partition size, just to be sure.
You should not be worried about size limits, a standard partition can be up to 4TB using ext2. Recent versions of ext2 can handle up to 32TB (see wikipedia for details). Every phone I have ever heard of can handle 64GB easily, but your phone seems to be limited to 32GB (according to the lg website).
Theoretically, you can make add as many partitions as you want to your SD-card, a quick scan through the Link2SD screenshots on Google Play show a selection for the partition to link data to.
1.5GB is not much today, as most phones ship with 8GB or 16GB by default. You can try doing some cleaning on your secondary partition, like clearing the cache and removing the data of apps that are no longer installed.

This is great. With the MiniTool Partition Wizard it's easy to shrink the FAT32 partition, however, I am unable to expand the ext2 partition. It simply won't let me do it even though there's 'unallocated' space right next to it. Any idea why?
Perhaps I'll just shrink the FAT32 and create a 2nd ext2 partition in the unallocated space. Then I'll use Link2SD to fill it up with apps. Does that sound reasonable?

I usually use Gparted (on Linux) to partition, but I installed Minitool to try and reproduce your situation, and it seems I was wrong about resizing ext2 in Minitools Partition Wizard. I'm looking for alternatives right now...

I'm sorry, but I couldn't find any Windows tools that allow resizing an ext2 partition.
Assuming Link2SD supports 2 partitions, adding a partition probably is the easiest option if you want to stick with Windows.
Another option would be to create an image of the ext2 partition as a backup, then deleting the partition, creating a larger one and copying everything back. This requires more knowledge about partitioning and filesystems though.
Alternatively, you could try booting a Linux live disk (works without install) and use a tool like GParted, which does support resizing ext2.

Wow. That's awesome that you would go to all the effort. Thank you for the help and good to know that I'm not crazy. All of the choices (a) backup, reformat, resize, b) Linux VM with Gparted and c) 2nd ext2 partition) sound like quite a bit of work, but I'll try the third sometime soon. I don't want to brick my phone before a trip so perhaps when I get back.

I had an issue with mini tool but used Aparted on the phone and it worked like a charm https://play.google.com/store/apps/details?id=com.sylkat.AParted

Update from ADB option under recovery menu
How does one typically use the "Update from ADB" option in the Recovery menu? Do I have to connect the phone via a usb cable to my laptop & provide the necessary update files?
Where on the laptop do I keep the update files & where will I download these files from?
In case my phone model helps it is a Moto G 1st edition XT1033.

IDK which Recovery (stock/custom) your device is running because in my device CWM 6.0 for Android 4.2.1 shows "Install zip from sideload" option. Anyhow, I've verified that both options points to same thing i.e. sideloading from PC.
This option will allow you to push a .zip file into the device accompanied by an automated installation of it. For a custom recovery this file can be any app, binary or system update. For a Stock recovery, you'll have to see what it allows to push. (I'm assuming you can only push signed system updates from them.)
The usage is simple. Choose the option in recovery which will show some output like:

Send the package to the device with adb sideload <filename>...

Your device (as obvious) has to be connected into PC with ADB drivers installed. Issue the command adb sideload filename.zip where filename.zip is the .zip file you want to sideload. It will show some processing and eventually will install.

@FirelordThanks for the tips! Is there a way to tell which Recovery I am running? I am sure I have not added / changed the recovery so my Recovery is whatever Motorola decided to ship with the phone.  If it helps the screen says "Android system recovery <3e> KXB21.14-L1.40"

If you haven't changed the recovery, then it's a stock recovery. Don't bother to search or note down the version number of it. It won't help you to get anywhere. :) Also, some popular custom recoveries are CWM,TWRP and Philz touch. If you happen to have any of them then you'll be able to see their name easily.

I'm thinking of using the file posted on this site listed as "Moto G (Falcon) Factory Firmware Images" My phone is an XT1033 and purchased in India so the version listed as "Retail Asia - ASIARETAIL_XT1033_5.0.2_LXB22.46-28_cid7" seems my closest bet. Just thought I'd post to see if I am doing anything obviously stupid?

One puzzling part is that that file is  an xml.zip. Will that work to install the way you described or do I need anything different for that format?

@curious_cat The link that you mentioned has a flashing guide which links to this. It is mentioned that if you've download a .xml.zip file then you'll have to use mfastboot to do the flashing.

Yes, I saw that link. I just wanted to avoid messing with mfastboot if at all possible. I guess not. adb seemed safer. The mfastboot instructions are real low level and numerous. Lot more chance to brick my phone IMO. Guess I must take the risk.

Let us continue this discussion in chat.

Battery quickly discharged after installation of Lollipop
I have Samsung Galaxy Tab S 10.5. Recently I've updated it to Lollipop 5.0.2 through Odin. Then problem with battery have arisen: charge falls on one percent each three minutes when brightness is medium, 3G is on, screen is always on and music is enabled.
Does this problem really relate to possible confrontation with Lollipop?

Go through some answers related to battery life and Lollipop. Check the battery usage of applications in power management. If everything is okay then it's time to change the battery.

You can look into which specific app consumes more battery in the Settings-> Battery or you could post the screenshot of the image graph in this question

@MANI : it's in usage only for two months.

@John You could have mentioned that in the question itself :) Have you checked battery usage?

@Lucky and to MANI: battery usage is normal - the most intensive battery exploiter is display, while the other components (OS, applications) use charge significantly lower.  Now I think that the deal is in the fact that after each installation of new Android OS I have to calibrate the battery. May it correspond to the possible solution of the problem?

@JohnTaylor since the screen is big for tablets it will consume battery heavily even if it is configured to lowest brightness settings..i think a fully charged tablet drains the whole battery in 5-6 hrs in normall usage..so i guess your tab with screen on forever should give you 2-3hrs which is normal considering your usage..

also you may want to try these to increase the battery life..http://android.stackexchange.com/a/478/27149

@JohnTaylor - Music is ON, 3G is ON, Display brightness at medium and is always ON - so battery is normal and healthy because it is a tablet first of all.

Cannot sync contacts from Google
My Moto G 1st gen running on Lollipop does not want to aggregate Google contacts from my contact.google.com list. The Contacts app does not allow me to import contacts from Google account. It also does not recognize the Google account in the Contacts > Menu > Accounts - I can see Facebook account and Skype account, but not the Google account (even when it is visible in the Settings > Accounts).
I cannot add any new account. When I click on the "Add account", it gives me the possibility to choose 2 "Exchange" accounts with the Gmail icon, but for both of them, when clicked, it says that there is already a Google account on the device.

I have tried to reinstall with no Facebook account introduced, does not work
I have tried to pass via Google+, it imported the contacts from Google+ without the phone numbers.
I have restored the SMS (backed up previously from my phone) and it does not recognize the sender (only the numbers),
It does recognize some of the callers, but it still asks whether to add them to contacts, so most probably it is not from my Google contacts.
reinstalls, reboots, reformat - all done.

Do you have any ideas?

Application self uninstalls
I have a Galaxy S4, Eu version, not rooted updated a few days ago to Lollipop.
Today 2 strange things happened:
The phone was connected to charging cable but charge was interrupted when it was at about 80%, this morning I found it at 64% (checked on battery graph).
One app that I use daily, installed in main memory disappeared from home and from installed apps. If I search for it on play store it proposes to install it, not to open it.
I do not know if the 2 things are related. I did not uninstalled any app in the last few days and I am sure that yesterday the missing app was there perfectly working.
Do you think there is a chance to recover the data of the app? I tried to browse phone memory (connected to pc) but I cannot find anything. Maybe there is a better way?

if that app was installed on sd-card and if the sd-card is removed, then app won't be shown as installed. Check if you removed sd-card and your app was installed sd-card.

Do you have an app cleaner, like 360 security or cleaner app? If so, uninstall it because some cleaner apps delete the apps. I have same issue: no app in home screen, but the apps data is in the folder Android/obb or data.

Uninstall Cleaner apps
Delete the .obb file in Android folder and reinstall again.

Why do apps like WhatsApp, Facebook run background services in android even though their apps on iOS without backgroung services
What is the reason for apps like WhatsApp running background services in andrioid even though in iOS they work smoothly without any background service

Because they can.
In Android you can create background services and do a lot with them, whereas in iOS Apple does not allow you to do this. Both use push notifications to get your new messages when the app is closed, so the main functionality of the app works fine regardless, however the apps may be doing more processing or monitoring, or whatever Facebook wants it to do in the background while you're not using it.

How can I make persistent changes in root directory (/)?
I have to edit my fstab in android 4.4 but the root is mounted in read only.
I've try to remount the root with
mount -o rw,remount /And I can edit the root files but when I reboot the device the changes disappear.
How can I make persistent changes in / without rebuild the kernel?

Does this answer your question? Any changes to files in root directory (/) are gone after reboot

For that you'd need to edit the corresponding image (see initrd), which is unpacked on each boot.
Alternatively, you could create a script replacing the fstab file, and have this run on each boot e.g. using tasker or a similar app that can execute "stuff" automatically after boot.

How do I delete a cloud printer?
I have 2 Google accounts.
When I was first hooking up cloud printing, I connected my printer with account A and then shared it with B.
I then realized that I preferred to have cloud printing go through account B.  I deleted the printer from account A and connected it to B.
I can now cloud print through account B, but the account A printer still shows up (greyed out).  Worse yet, it's the default printer.  So, every time that I cloud print, I have an extra 2 clicks.
How do I delete a cloud printer that it is no longer to be "shared" with me or, at least, change which cloud printer is the default?

You can delete cloud printers through this page. I've never been able to tell how defaults occur, though. It seems to mostly do it by what was used last, but randomly it doesn't. Sorry I can't give you a good answer on that part.

Nexus 5 in Recovery mode not detected in ADB but another Nexus 5 gets detected
I think I soft bricked my Nexus 5.
I was planning on wiping all data from Nexus 5 and installing Cyanogenmod 12.1 following the normal procedure in the Recovery Mode but the wiping got stuck at Wiping Cache for very long and I ended up rebooting the phone.
My phone has ever since been showing "Unable to mount /cache" error.
To fix everything I thought of installing a Stock ROM image from ADB but my phone does not get detected under the devices list when I run "adb devices"
I have installed the drivers and to test I connected another Nexus 5 which did appear in the list but my phone does not.
Any ideas on how I can proceed to fix this issue.
Any suggestions or help would be really appreciated.
Thanks.

Because you want to install a new ROM you wouldn't mind erasing your cache partition from scratch. You can try a fastboot ROM and erase+make the cache partition using the fastboot flash command. Otherwise, fastboot has the erase partition parameter as well. IDK how to use it, may be Google can help here. // This would be possible only when your device is detected in fastboot mode on PC. What's the status?

That is exactly where I am stuck. I have manually installed the drivers. Other Nexus 5 gets detected in adb and fastboot but mine does not. When I do "adb devices" my phone does not show up. :(

There are devices that doesn't show up in ADB devices but in fastboot mode. Fastboot will show devices only when the device is booted into fastboot mode and not into Android system. Have you confirmed all these scenarios? If nothing works, I advise looking for some low-level flashing tool which doesn't depend upon fastboot or ADB.

hi Firelord.. i got it to work. the problem was with my usb cable i think.. it intermittently disconnected my phone from the laptop and that ended up in windows thinking of my phone as an unrecognized device.. thanks for all the help though.. appreciated.. :)

Yup. Posted it. :)

lost my phone .bought new phone got same number.how do i get my contacts
I lost my phone LG34 today. I've purchased a new phone and had the data restored but I don't know how to retrieve my contacts.
I'm not too bright with computers so please explain in simple terms how I can restore my contacts.

Login to your Google account and turn ON the "Auto Sync". All the previous data including Contacts, Calendar, etc must restore.

You should be able to track your phone with android device manager. PS: login with the same Google account as on your lg34.

Unless the contacts were synced with Google or any other means, they are lost.

but if the contacts were synced then he could be able to recover them.

true that, but the OP didn't mention anything about if they were synced or not.
So basically it's an incomplete question.

If your phone was synched with a Google account, you can go to Settings > Accounts (that may vary on devices) and sync with google, after a few moments, your contacts (and various other stuff) should come back.

Softbricked phone
Alright, so I used this tutorial and after step 3 no my phone only boots up and says "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again"
So I tried installing the stock 4.4.2 and that didn't work, ended up with errors like Fused 3 > binary 1 and Something 2 > binary 1.
I should mention I got the Lollipop OTA update awhile ago, so I was all the way up to date. I'm guessing the issue here is that I'd need the stock image for the version I had before I started messing around, but as far as I can tell that's not available.
Not sure what to do here, but for now I'm completely cut off from communication so I could use some help!
I have the SM-G900A

The link meets the dead end: 404 not found. Please [edit].

I think it's this page. I've submitted an edit.

Yeah you guys are right about the link. Also, I ended up bringing my phone into a Samsung guy and he fixed it. From what I read maybe wiping and rewriting the partion was the fix.

Can I install custom ROM on Android mobile having low internal memory?
I want to install the latest custom ROM like Lollipop but my mobile has low internal memory, about 150MB.
Will that be a problem during the installation of the new custom ROM?
I have already rooted my phone and I'm worried that my mobile could get bricked.

No it will not effect
Just place the ROM in sdcard and flash it through custom recovery by following given steps properly and flash the ROM which is developed for your device  otherwise you will end up having bricked your phone.
If your device have low RAM it may become laggy.
Share the link of ROM that you want to flash and detail of your phone.May be we can help you little better

As long as the ROM was built for your device, it shouldn't be a problem. However, like what Ash-Ishh mentioned, you'll probably experience some lag.
You can also try looking up other forums to see if anyone else has flashed the same ROM on a device the same as yours and see if they're successful in the flashing.

like previous comments, if it's built for your phone it'll boot up and work properly (unless the developer is a noob).
but your problem can be taken care of by one to these two methods

you can swap the internal and external memories by a script (you have to find that, sorry).
Partition your external memory card and format it to ext4 and with other script you can use this partition as your internal memory. (in this case if you remove your external memory card you'll get boot loops)

If you have root, you can install a partition manager app like

Garted or
AParted

And don't worry, you cannot brick the phone by flashing ROMs.
If the ROM is not designed for your device, it won't boot but you can flash the latest official room from your manufacturer.
And you mean the total space or is that 150 MB the user partition?
Go to Lineage OS as they have most ROMs for most devices
Do not install to SD card as mostly old phones do not support SD card boot. Some devices don't have even recovery and boot partition by default, so in order to have a bootloader to support such, it needs to be custom made to include extra functionality like SDcard and cloud boot, pxe.
But if the entire nand chip has just 150 MB,  maybe that is the RAM and not the ROM. Watch closer, take your time.
But if that phone has just 150 MB total nand space, well it won't even have a 3G network, so maybe the 150MB is the free space that you have provided the phone specs, look at About Phone in Settings.
Use an app like AIDA64.

Is my brother's phone unfixable?

This is the screen my brother's phone stays at, no matter what action is done, after his phone died and he tried to plug it in. I've seen similar images but most ways to fix it seem to be "flash a new rom" and even then, the images that were posted in that case didn't have those invalid_ver_info notices.
Is my brother's phone dead or can it be fixed, preferably without flashing the rom and possibly doing more harm than good.

first of all, relax. You just need right hands with right tool. But, only flashing know-how will not help much. Need deeped expertise.

The same thing happened to a friend of mine and according to him, the following solution worked:

Use the volume buttons to turn the phone off
Switch it on using the power button
If this screen appears again, reboot into fastboot
reset the phone via a windows computer

fastboot devices
fastboot erase userdata
fastboot erase cache
fastboot reboot

If nothing works, play around with the phone and learn something new!!

Doesn't this require an unlocked bootloader?

I was assuming that yours has an unlocked bootloader... :/

Assuming without mentioning creates misunderstanding and a frustrated user might even downvote your answer for this deliberate mistake. Please avoid this in here and in any answer in future, and make an edit.
