Can I bypass the Google Verification on my Huawei Mate 8?
I just bought a Huawei Mate 8 and I can't set it up due to the Google account verification in the setup process. I've messaged the seller asking for the account details but he doesn't know. I don't have an OTG cable or USB and I need a way to get past this so I can do a full reset of the phone. Please help! (This is different to the other questions as the factory reset option still leaves me with the same problem with FRP and I can't use ADB because I can't enable USB debugging)

Pretty much every phone can do factory reset while turned off, try this:

Turn off the Mate.
Press and hold at the same time: Volume Up + Home button + Power button, until you see Huawei logo.
Then select from Recovery Mode menu “wipe data / factory reset” using Volume buttons to navigate and Power button to confirm.
Select “Yes — delete all user data” to confirm the whole operation.
After that select option “reboot system now”.

And be happy after the reboot when the question pops up to provide credentials of the original account. The general procedure for a factory-reset is one thing, Ivo, but that new "protection" causes trouble for many.

Yeah I've done that a few times already but the Factory Reset Protection is still enabled and I can't find anyway to disable it.

Cat B15Q pairs with Toyota, but connection unusable
I have no problems pairing my Cat B15Q (Android 4.4.2) with my 2013 Toyota Auris over Bluetooth. However, it stops there. As soon as I try to use the connection (make a phone call, play music, access the internet), the Toyota complains with a non-descript error message.
I have been able to successfully connect a WinPC with the phone (incl. file transfer).
Does anybody know any tricks? I have tried the obvious ones: deleting the connection, re-pairing. To no avail. The car can use my wife's iPhone 6 over Bluetooth. I have contacted Cat, but they say the problem is with Toyota. When I see the long list of phones compatible with my car, I can only wonder why my phone isn't working and why the problem should be with Toyota?

Last week, I had to turn in my (company car) Toyota and I got a Peugeot 2008 in return. Of course I tried to connect the Cat to the car. Pairing was no problem. Making a phone call, however, was not possible. But receiving a phone call was possible! This got me thinking. The Cat is dual SIM and in fact I have two SIM cards. In the settings you can choose which SIM card to use as default for outgoing calls, or whether to postpone that decision when actually making a phone call. I had chosen for the latter option, but after I changed it so that outgoing calls always use one specific SIM card, I could make calls with the car's phone buttons!
Maybe the connection with the Toyota had been successful after all, it just got stuck because I hadn't opted for the default SIM card option.

"Listening..." screen suddenly popping up on Android 6: what is it, how to disable?
Every now and then, some Google "Listening..." screen pops up , like this:
 full resolution
FYI: my device is a Nexus 5X with the latest stock Android 6
I have no idea what this is, and worse: I don't know how to get rid of this. It seems to occur when my earphones (not headset or mic, just earphones) are plugged in. But not consistently, I can't deliberately reproduce this.
Upon searching around I found some suggestions this may be related to Google Now or OK Google, but both are disabled already.
How do I prevent this from ever showing up again?

Try holding your home button  for 2-3 seconds. Then press on the G logo. Top left click the "settings" icon. Go to settings. Voice. Ok google detection.  Disable "From any screen"

In case the above comment doesn't help, try wiping the data of the Google Play Services and Google apps. If even that does not help, try a factory reset.

happened to me recently, with earphones plugged in, stopped happening when I unplugged them, had been walking with them in rain prior, propably the buttons on the earphones were short circuiting or something llike that .. atleast this stopped happening after a while ... perhaps when the earphones had dried off

This happens when you tap on the little Mic image In the Google search bar at the top of your screen on the right hand side of the field box.  It's the Google Now voice command interface.

Thanks for the suggestion but that can't be it. And I would know if it only happened when I touch a mic icon ;) It happens when I'm not touching the screen at all (also not accidentally, i.e. in my pants or whatever). Furthermore, I actually don't have the Google search bar (I disabled Google Now and later even switched to Nova Launcher instead of Google Launcher).

It seems to occur when my earphones (not headset or mic, just earphones) are plugged in

When you press and hold answer button on your headphones, Google app is automatically launched. Check your earphones' jack. Or try to blow hard into the connector

Yes I suspected it could be the earphones triggering some kind of event. But I have tried several pairs of earphones, including ones with NO button or interaction or any other functionality than merely outputting audio. Also tried blowing into the connector and cleaning the plug (jack), but no to avail.

LG G2 has horizontal stripes on the screen when displaying high resolution images with moire pattern
Recently my LG G2 sometime has horizontal stripes on the screen. Firstly I thought that these stripes appear randomly and the problem might be related to connection between the screen and other hardware. But today I realize that the appearance is not random. When I open a specific type of image, that is images with moire pattern, these stripes will appear. These stripes will disappear when I open an image without moire and appear again when I open another moire image.
The phenomenon reduces when I zoom in the image. Also, the stripes won't appear if I resize the image to smaller resolutions.
The stripes appear whether the image is displayed in the galaxy app, or the default web browser, or chrome browser. Even when I set the image as the wallpaper, the stripes appear right on the wallpaper.
I have delete the system cache but it doesn't help.
In the picture below, stripes appear when I opened a image of grasses which has moire pattern.

Have you ever encounter similar problems? And can you guess this problem is caused by the hardware or software?

Are you talking about the white lines where the flowers are, just before the big gray/white part of the image ?

@ИвоНедев: Thank you for your reply. I have posted another image which illustrate the problem. These lines have random color and keep blinking.

Ugh.. that doesn't look too good. You say it only appears on images with these colors and nothing else ? What happens if you zoom the image, does the stripes change/change position/move at all ?

Try one of these https://www.reddit.com/r/lgg2/comments/3efz9y/lg_g2_secret_codes/ and look for the screen diagnostics. See if you can make anything out of it. Are you runing stock android, have you rooted/instaled anything fromwtihing recovery/ etc ?

@ИвоНедев: I still use the stock android. The secret code works and I can access the hidden mode of the phone. But the solution in that link doesn't help. Thank you very much for your help ^.^

@ИвоНедев: I have notice that it's not the color causes the problem but the moire pattern in the image. I have test with multiple images which contain moire patterns and the randomly moving horizontal lines appear with almost all of of these images.

I'm going to guess It's a software issue.  Try viewing same photo with the stock Galleries, and google Photos to see if there's a difference at all. Also if you set for instance the second image from your question as a wallpaper, how's the lines then ?

@ИвоНедев: the lines still appear whether the moire images are displayed in the stock galary, stock web browser, or chrome browser.
I also set the image that I showed above as the wallpaper and now the lines appear right on the wallpaper. However, the problem is less severe since the image is displayed in full screen (the appearance of lines always decreases when I zoom in the image). Also, for the same image, if I resize the image to smaller resolution, says 320x180, the lines will not appear.

Is this stock android, or have you installed something custom ?

@ИвоНедев: it's stock android.

Connecting ipega 9037 Bluetooth gamepad via USB-OTG to smartphone
I have a problem with my device while pairing my ipega 9037 Bluetooth gamepad controller. The joysticks are working and also the D-pad, but I have thought that can I use this controller over USB OTG.
Does it damage the smartphone battery?

If you are linking it trough the cable and not Bluetooth, it won't drain much more battery than pressing the volume buttons.
In other words, nothing you'll ever notice.

I had the same problem with the PS4 controller. When I use OTG, my phone battery goes down.
I open up my controller and disconnect the battery. Then when I connect via OTG, it doesn't charge the controller. No more, it's perfect.

Swipe required before pattern unlock on Android 6.0 Marshmallow
I have a pattern screen lock set on Samsung Galaxy S6, and with the Android 6.0 Marshmallow upgrade, I must swipe before I get the pattern.
Can I disable the required swipe, and just open the pattern unlock screen?

While I'm on Samsung, I don't have a stock Marshmallow installed (having CM13 instead). From the research I did, there seems to be no way to enter the pattern/PIN/password directly without swiping first, if you're on a Samsung stock Android. There may exist a solution, though, if rooting is an option: there's an Xposed module called XTouchWiz, which claims to allow you a fair level of customization, while avoiding you to flash another firmware. From the module's feature list, I can see a "Fast PIN Unlock", so it may allow a fast pattern unlock as well. Hope that helps!

myLock utilities (Lockscreen improvements)
Does the job for me on my Nexus, Samsung Galaxy, and YotaPhone with Marshmallow and Lollipop. Work without root permission.
Screenshots:

I cannot confirm whether this feature would work on your particular ROM but it definitely works for stock Android 5.x and 6.x. You would need a rooted Android, compatible Xposed Framework installed and GravityBox [MM] installed and activated.
In GravityBox, under Lockscreen tweaks go to Direct unlock and choose Standard or See through. Select Default under Direct unlock policy.
(Click image to enlarge)

This would make sure to show the unlock phase of lock screen whenever the device is securely locked and screen is turned on.

1 Xposed Framework for stock Android [based] ROMs: Android 4.x, Android 5.x and 6.x

This is by design and cannot be changed without installing a different launcher. Personally, I like the swipe as the lock screen looks neater without the numbers on it all the time.
I think the reason this was done was to accommodate for the new Lollipop lockscreen notifications - instead of displaying in the status bar, they display on the lockscreen. There would be no room for them with a keypad in the way.

Well if it cant be changed, it is a bad upgrade that needs to be removed as there is now an additional step each and every time the phone locks. On the previous Android platform this was not the case and you were able to directly access the pattern lock, saving an unnecessary step. Upgrades in software are supposed to make the phone easier to use, not add redundancy.

Remove a contact from Hike which is already deleted from the phone but still showing on Hike
How can I remove a contact from Hike which I've deleted from my phone but still showing on Hike?

Maybe it will synchronise the contacts gradually.

Block the contact. It will remove that from your friend list.
Actually, it shows that contact because it is in your friend list, or you send it a friend request. So, as you block that contact, it cancels the request. Now you unblock the contact again, and it is removed from your friend list.

USB configuration within Developer Options doesn't save
Just bought a Samsung Galaxy s7 Edge with Marshmallow pre-installed.
I'm trying to get my phone to work with Android Auto.
The only way I could make my phone connect to my car is to enable Developer Options in the settings menu and change the USB configuration to "MTP Media Transfer Protocol".
My problem is that whenever I disconnect my phone, the change I made goes away and reverts back to "charging".
So, now, every time I want to connect my phone to use Android Auto, I need to enter the settings and change the USB configuration back to MTP for it to work... really a pain in the butt.
Does anyone know if this is an Android issue or a Samsung issue? Also, is there a way to correct this?

It is status-by-design. Might help out: Default USB MTP for Android 6.0

I can confirm that this issue is not limited to you. This is the same on my Nexuses (running Marshmallow) and it's a pain.

Android - How to make a contacts group invisible to whatsapp
is it possible to create a contacts group in my Android that wouldn't be visible even to whatsapp "show inivisible contacts" ?
I mean, I don't want that group to appears in whatsapp what-so-ever
If not, is there any app that can easily hide (ie, remove a group from Android contacts) and unhide whenever you want?

The question is not specific hope so. Do you want to hid yourself from certain friends who are in your contact list?
If so, then you can add them to block them in the block list. (But you will be still receiving the messages from them).
Or change your privacy settings in whatsapp according to your convince.

This idea might be helpful:
1.Backup the contacts which you have hide it.
2.Delete those contacts from your people.
3.Now Synchronize the contacts and do refresh in Whatsapp. Now you got to see no contacts, I mean the contacts which you try to hide.
4.Available Possible ways : (A) Go to Settings > General > Accounts > Whatsapp > Untick the option. (B) In Whatsapp, Go to Menu Button > Settings > Contacts > Untick Show all contacts. (C) People > Menu > Accounts > Untick Auto-sync app data
(Click image to enlarge)
Phone Settings > Whatsapp >  People >
5.Reboot your Phone.
6.Now restore those contacts.

I mean, I don't want that group to appears in whatsapp what-so-ever

If this is made possible by WhatsApp, how are you suppose to send message to that group? If you cannot send the message, then what is point of having that group?
You may want to check the WhatsApp FAQ but AFAIK there is no mention of Hiding the group in Whatsapp.
If you do not want to send the messages from that group, you can simply exit the group
Another option is to mute the group. You will still receive messages sent to the group, but your phone will not vibrate or make noise when they are received.
If your only intention is to avoid "other people" from knowing which WhatsApp group you belong to, then you can use Locking apps to achieve it.

If not, is there any app that can easily hide (ie, remove a group from
  Android contacts) and unhide whenever you want?

That group is specific to WhatsApp and is not known to other parts of Android system as well as to other apps.
It is very unlikely that WhatsApp will allow other app to operate(hide/unhide) on the User data belonging to WhatsApp. Not possible AFAIK.

I don't think the question is about groups inside WhatsApp, but about groups/categories of contacts in the Contacts/People app.

@DanHulme Shall I keep the post or better to remove? I assumed it to be for whatsapp

It's up to you, but I don't think it's relevant to the question.

I think Hide Contacts could be what you are looking for. It can't be read by other apps and you can call or send message to a hidden contact, import contacts from the default app and it also has caller ID.
I was also looking for a similar app, didn't find it so I decided to develop one myself.

Can't uninstall virus plus phone keep rebooting
I have a rooted Samsung Galaxy S3, running the stock ROM. I downloaded "root manager" app, and since then 3 more apps appeared - "file assistant," "mp3 free downloader," and "sexy." I factory reset my phone many times but yet these apps are still there, and I can't uninstall them. Also my phone began rebooting since this happened (i.e. since these apps downloaded yesterday).  How do I get rid of these apps, and repair my phone?

They might have turned into system files. If you have ES File Explorer installed and grant root access to it, you might be able to remove them.

Stock rom . I was going to flash a new ROM in hopes of deleting the virus

It sounds like malware has sneaked into your phone's system area (possibly via the "root manager" app you installed.) System area does not get touched during factory reset, which is why the apps are still there.  The /system partition is usually write-protected by default, but root privileges allow apps to write there as well.
The best way to get rid of such malware is to restore the /system partition.  This is accomplished by re-flashing of the firmware.  You can usually find stock Android firmware for your phone on the manufacturer's website, or other trustworthy sources (e.g. XDA-Developers device forums, SamMobile.com, etc.)  Alternatively, flashing a custom ROM (e.g. CyanogenMOD) will also erase the /system partition, getting rid of any malware that managed to get installed there.
Specifically, you will need the Odin tool, Samsung USB drivers (so that your PC recognizes the phone in Download mode,) and the image file specific to your phone's model number (Galaxy S3 has many variants, make sure you are downloading the proper firmware, or you may end up with a non-functioning device.)  Shut down the phone, and start it while holding Power, Home, and Vol Down buttons together until it shows the Download screen.  Install the USB drivers, and connect the phone via USB - it should get recognized by your computer.  Run Odin program, make sure it sees the phone (one of the COM ports will be highlighted,) press the AP or PDA button and select the firmware image, and click Start.
If you are knowledgeable enough, you can start the phone in recovery mode, and then using adb browse the /system partition and attempt to find and delete the malware.  However, this is a task for advanced users.

Thanks for your answer. I was going to reflash the ROM but when I go and download TWRP the phone keep rebooting so I can never successful finish the downloaded.

By the way I voted on your comment but its not showing saying I don't have enough Rep?

@LostPecti You need 15 rep to be able to vote. Comments, and posts alike

@LostPecti You should put the device into Download mode and use Odin to flash the ROM.

I never heard of it, did a quick google search looks simple let you know the results.

@LostPecti check our odin tag-wiki ;)

Thanks Izzy and  Matthew it worked and I got the virus. Thank you guys. It also allowed me to expand NY knowledge ;)

Android tablet presentations: networking and equipment?
To start, a bit about myself.  I follow instructions really well, but I'm otherwise clueless on the how or why that things work when it comes to electronics.  I've built PC's several times from parts, but only because I did what I was told, and everything worked out each time.
What I want to be able to do:  I want to be able to hand out two 10" Android tablets to my clients when I meet them at their homes to do real estate listing presentations.  I want both of those tablets to mirror a device that I hold, running a powerpoint presentation, so that as I move the presentation on and am talking, it will likewise shift on their screen (it can't be automated, because I get sidetracked by a lot of questions).  Essentially, I want them to be able to hold and look at my presentation, while being able to look up at me while I'm talking them through it.
Limitations:
1) I don't want to use the internet to accomplish this, as it wouldn't be professional for me to request to use their wifi, and some people don't have wifi.
2) I would also prefer not to use a mobile hotspot requiring a data plan if possible (though I'd consider it if there were no alternative).
3) I would really like to mirror on two devices from one, so that I can hand out more than one tablet to owners.  Again, if this isn't possible, one would do.
So is this possible?  Would this be something I could do with bluetooth, or perhaps a wireless router used to connect the devices offline?  I honestly have no idea, nor if I'm even on the right track.
Thanks in advance for your help.

There are many possibilities for making this happen using different apps/services. But...kindly note: Playing a same ppt from single source on all three devices (one yours, and two for your clients) doesn't seems to be possible until they are connected to the same WiFi router (may be a offline router) but to be able to share screens using some screen-cast app or remotely controlling their presentations using team viewer sought of apps, the basic necessity is, that they all must be on same subnet.
let me know if i can help you further in accomplishing your this task..
Hope that answer your query as of now..

Well dude, this part has nothing to do with your question asked above, Its just a little piece of advice from my side.
Instead of taking pain of carrying three 10" devices and those too wont be collectively able to cater the need of more then 2-5 of your clients, i would suggest you to carry this device. As this definitely seems to be more useful for the kind of solution you are looking for. :)

Not receiving incoming messages on my mobile
I'm using a Samsung Galaxy S2 mobile.
Since last week I have not been receiving any kind of incoming messages on my mobile.

I tried message centre no. deleted and re-enter, and powering off my mobile and restarting also.
My network setting also perfectly cross-checked, but still the problem was not resolved.
I called many times to customer care, but they are not properly responding at all.

Are you referring to SMS and MMS?  Do calls and mobile data work?

If its not a network related issue then the problem could be from device itself. As Samsung Galaxy S2 has a built-in spam functionality in messaging.
So inorder to verify the same, just try sending sms with any another device on your S2 and just see if the other device gets a delivery confirmation report or not, if it does, and you still don't receive that sms. Then in this case you've unknowingly/accidentally switched on the spam function your Galaxy S2.
Follow the instruction below to unblock your incoming SMS
Using the Settings menu

From any Home screen, tap Messaging.
Tap the Menu key.
Tap Settings.
If necessary, tap Spam settings to select the check box
Tap Unregister number as spam (if any)
Touch and hold on the desired number and then tap Delete
Tap OK

Hope this would resolve your problem :)

How can I fix a boot loop after replacing the Power button?
A couple days ago my phone started boot looping and just showing the Samsung logo. I was told that my Power button was the problem, so I replaced it but I'm still having the same issue.
I have a Samsung S4 Mini i9190.

Did anything else happen before this issue occurred?  Have you tried a Factory Reset from Recovery?  You may need to flash the stock ROM.

You should get it inspected by an Authorised Samsung Service Center. Similar issue happened with one of my Samsung Galaxy Device too, they diagnosed that due to over heating of device while gaming or heavy usage sometime device CPU mounting on motherboard (which is done my lead balls) gets cracked causing connectivity issues between CPU Chip and motherboard, resulting in boot failure, or boot-loop. So in my case they had to replace the motherboard to fix the issue.
Though in your case its not necessary its happening because of same reason as of mine, there can be numerous reason for similar fault. It could be something very minor connectivity issue as well, as most of the Samsung devices cause this error due to corrupt OS and at time due to a faulty charging connector too.
Bst thing is to get it checked from Samsung Authorized Service Personnel/Center.

How to check that an Android device isn't being used in a botnet / sending spam emails?
I've discovered that my home network IP address has ended up on several blacklists after spam traps received emails from this IP address. I've tested the one PC that uses this network, and it seems to be fine. That leaves the most likely culprit looking like one of the two Android devices on this network.
On a PC, common ways to check for botnet-type activity include checking traffic on specific ports, and monitoring outgoing traffic. Is there any equivalent for Android?

I've searched on this but found nothing beyond generic anti-malware articles talking about antivirus software. I've not found anything specific to spam or unsolicited outgoing mail, and common anti-malware apps like AVG and Avast seem to only mention spam in the context of preventing incoming spam (not a problem for me), not outgoing.
If possible, I'd prefer a solution based on checking for the actual malicious activity (i.e. detecting actual outgoing mail), rather than relying that an anti-malware app has its listings up to date.
If possible, I'd also prefer to not need to root the devices, or change the operating system from the manufacturers' (Samsung and Sony in my case).

Without rooting it would most likely be easiest to intercept the traffic at the router/gateway.

I was actually just researching whether this is possible on my router. Not found anything yet. Any suggestions on how to start finding out how to monitor my Android device from the router would be welcome!

Looks like it's impossible from my router. I had the idea of turning my PC into a wireless hotspot then monitoring the Android device traffic from it, and asked a SuperUser question to see if that's possible, but direct monitoring or botnet-specific checks from the Android device itself would be better, if possible

I suggest using the Android VPN feature to route all of your network traffic to an OpenVPN server. This will send all traffic, Wifi and cellular, through one chokepoint where you can log and analyze it, and it will do so regardless of what network the phone is using. Then you can log and analyze traffic from the OpenVPN server using any of the standard tools.
For an example of a project that uses this approach for a different sort of network security analysis, namely to find apps that send data over unencrypted or insecurely-encrypted connections, see nogotofail.

Effective storage ridiculously small since Marshmallow update
I have been using a 16GB HTC One M8 for the last two years with no major hiccup (although I met the infamous infinitely growing .thumbdata file taking 8GB from my storage just because, fixed with a factory reset then disabling the gallery app, and now seems fixed in Marshmallow since I can't see it anymore), but I'm now facing something way trickier.
My storage is CONSTANTLY low. I use a 32GB SD card where I put most of my stuff (music, pictures, downloads etc), so my internal storage is rather unused - it's only used by the few apps annoying enough to not support SD card (like Whatsapp) and they aren't taking that much space anyway.
I checked numerous ways to analyze my storage:
Android system's storage analyzer says 15.88 GB of my 16GB are being used. Of this, it counts:

System: 9.07GB (really? Nine gigs for the system? This seems a lot but oh well)
Apps: 4.85GB. This surprised me as I don't have much big apps except one ~400MB game. I checked the app list, checked and cleared the caches for the biggest apps (which weren't much anyway, I only have three apps over 300MB - including data - and their data/cache isn't much), and funnily enough if I add all of the apps' storage usage I get around 2.2GB. Where are the extra 2.65GB from?
Images: 244MB - meh, just random downloads etc, won't help
Audio/video: 10MB (my audio/video is on the SD card!)
Downloads: 151MB
Others: 1.49GB, includes my podcast app with the local podcast cache, reader, whatsapp stuff that I empty every once in a while anyway - I don't want to keep deleting the 500MB of whatsapp images/videos I have just because my phone is dumb!
Cached Data 69MB

So here I see two problems: Why is it detecting way more apps than I have? As an example, I removed Cytus (1GB app) about two weeks ago to free some space. My phone is already low on memory and I don't know what the hell have I done to get 1GB extra in there... Haven't installed or downloaded anything since then yet this 1GB got magically filled somehow. Also when I click on "Make more space", it tells me that there are only 2.21GB of "Removable apps", which is consistent with what I calculated above - why?
I factory reset it about two months ago to get rid of the thumbdata files, and now I'm back to having no memory available just because. So I went on two different apps to look for answer
Alternative 1: the app 'Drives'
Link for the app here.
When scanning my internal storage, Drives says that my drive space is 10.68GB (which I guess is the accessible storage, rest of it being system?). However, when I check the drive usage, it only gives me a 2.88GB total, split between apps, whatsapp etc.
I checked the files by size and the two biggest files Drives show me are 418MB (a game .obb file) and 159MB (another game .obb file). Won't tell me anything else about the remaining storage!
Alternative 2: the app 'Storage Analyzer'
Link for the app here.
Alright this it where it gets interesting. According to this app my accessible internal storage (/storage/emulated/0) is 10.68GB (consistent with 'Drives'), with 10.39 being used (I'd guess the remaining 5.32GB are system, which sounds way more plausible to me). And according to this app, I have:

2.9 GB "Used by publicly accessible files"
7.49 GB "Used by Android/inaccessible files"!!!

Basically according to this app I only have access to about 2.9GB of data that I can actually read, delete etc. What are these 7.49GB of inaccessible files? I can't see them on any app! I also checked the DCIM folder to see if I had another case of infinite thumbdata file, but couldn't find any.
So here I am struggling to actually use my phone. I have to use Gmail through web since it won't synchronize on low memory, and I can't download a single app. Would anyone have any idea why most of my internal storage is eaten up like that? How am I only allowed to use 18% of my total storage?
If you need any other data please let me know, I'll try emptying stuff to download other apps if needed
NOTE: My device not rooted - could root it if needed but well, I just never did it cause I didn't really need it.
EDIT after suggestion, I tried looking at what DiskUsage says:
I can scan App Storage and storage/emulated/0
/storage/emulated/0
DiskUsage says it is 10934 MB. Includes:

7647MB of "System data" - damn is the HTC software that heavy? My Nexus 9 tablet has around 4 GB for the system. Any cache to clear maybe?
About 2 GB of other stuff, which is consistent (whatsapp stuff, applications obb files, podcasts)

Surprised at the big amount of space the system gets - how would 8GB phones ever live then
App storage
DiskUsage says:

4575MB of Data
3813MB of applications (!)

In all the applications, I see a whole lot of system apps that don't take much space but are required and I can't uninstall them. I'd say that's pretty consistent with what the system storage analyzer says: 2.2GB of "extra apps I can't uninstall". I'll assume these apps are system apps (since I see a lot of HTC sense stuff etc).
Which would mean ultimately that the entire system (system files + unremovable apps) takes around 10 GB - this sounds like WAY TOO MUCH for a smartphone. Then my personal storage is basically 2GB of apps and 2GB of data for certain apps - ridiculously small!
Is there any way to see what the system files are composed of? I wonder if there are some stupidly big cache files in there?

I had the same issue for quite a while, unfortunately I don't have a solution as I had tried clearing cache from boot etc.
My "Solution" would be to wipe your phone and then combine the SD card storage with the phone if you have Marshmallow.
My phone now reads the 32gb + 9gb usable phone storage as a single partition.
I am posting this only because you received no other replies after writing such a detailed question and my own research into it yielded no solution either.
If you happen to have found a solution please update the question.

How to fix android-x86 install on VMware?
Using android-x86-4.4-r3.iso, I created a virtual machine in VMware Workstation 11.0.0 on Mac OS X.  I just clicked Create virtual machine, chose my Android ISO, and just hit Next repeatedly until finished (just like I do to create Windows VMs).
I'm not a master at VMware. What did I do wrong in there? I ran into trouble, as in this picture:

I wait, but it doesn't change. If I am supposed to enter a command, I don't know what command. Can anybody help me?

You need to follow the instructions.  Specifically:

You have to change your virtual disk type to be IDE because the default type in VMware is SCSI, and [the] Android-x86 kernel is not configured to support SCSI. You can follow these steps:

Create a virtual machine.

Edit [the] virtual machine settings after the virtual machine [is] created.
Choose the hard disk and remove it.
Add a hard disk to create a new virtual disk, then you can choose IDE as your virtual disk type.
When finished, you can install android-x86 normally.

Thanks you so lot, Matthew Read. It really helpful for me. It work!

On windows, installing the recommended iso for vmware (android-x86_64-9.0-r2-k49.iso) let you stuck at command prompt.
And if you try the debug startup, you might get stucked with a confusing message

random: 7 urandom warning(s) missed due to ratelimiting

Since the live boot vesa start mode works, the urandom error is not the problem.
Rather, the required video acceleration seems to be missing from vmware.
As a result you need to configure grub to start androïd in vesa mode.
This can be accomplished following a procedure described here with some mistakes or incompletness or a little outdated.
After the standard install, you need to

reboot,
On grub boot choice (white text on black background), keep first choice and type 'e'

After that, you can see existing boot commands in the boot sequence.
- Select the upper item and
- press e once more
To edit the boot command for GRUB, Use arrows to reach the right position

replace the word "quiet" by "nomodeset xforcevesa", you should have:

kernel /android-?.?-r?/kernel nomodeset xforcevesa root=/dev/ram0
  androidboot.selinux=permissive SRC=/android-?.?-r?

presse enter to save. then b to boot.
For the grub configuration to persist upon restart,
edit its configuration file:

mkdir /mnt/sda mount /dev/block/sda1 /mnt/sda vi
  /mnt/sda/grub/menu.lst

Press "i" to use insertion mode:

replace the word "quiet" by "nomodeset xforcevesa",
escape to go back to command mode.

Then
ZZ or :wq!
to save and quit
You now can restart your vm using your custom configuration.
If ever you wait too long without any action,
your screen might turn black, entering the sleep mode.
Use your keynoard's menu key to recover a usable screen.

Wi-Fi Connection Issues
Very recently the Wi-Fi Connection on my Verizon Galaxy S4 has decided to turn itself off at will. This issue is device specific as I have other devices that are not experiencing this problem. The device is Rooted. I have tried: setting a static Ip, resetting router, switching airplane mode on off, changing channels. None have worked. Next is a factory reset, which I do not want to do. So in summary, does anybody have any more tricks I can try to solve this?

Possibly there could be couple of reasons for this sought of behavior from your device..

Check if it happens only when any battery power saver app is switch on, as most of the inbuilt/third party battery saver apps have access to your device's WiFi functionality and they switch it off whenever there's a event triggering the app's pre-assigned/pre-programmed parameter telling the app about high usage of battery by device Wi-Fi transmission/reception.
Another Scenario which might make this happen is the low WiFi signal. Mostly all higher versions of Android OS have this inbuilt functionality to turn off the WiFi whenever available signals falls to a certain level. Some device manufacturers provide advanced setting under WiFi setting to enable this control of OS, while some keep this function as preassigned in OS disabling user. Look for WiFi Sleep Policy in your device settings and update the settings as per your requirement. You can also refer this tutorial to learn more about adjusting the Samsung Galaxy S-4 WiFi sleep policy settings.

Hope adjusting your device WiFi policy will will resolve your problem, incase if ever after the adjustment of WiFi settings, you still face any issues do revert back with exact situation, I'll try to look deeper into your case.

I have six Samsung Galaxy Avants that I can't do much with
The owner of my company upgraded our employee phones to something more current. He was going to literally just throw away six perfect condition Galaxy Avants with cases and chargers until I asked if I could have them since they were trash to him. He said sure.
So here I am, stuck because the company software is still on here. I can't really delete because I need admin permission and the application that we used is actually no longer in service (our admin and her team built a new app for the new phones)
I don't really know how to word this, because I have not really been in this situation before...But how can I get these phones back to factory settings? I have the passwords to get into the UI like you would normally but it's still recognizing that it is a phone for my company, with the no longer working app, and no ability really to navigate the phone because it wants me inside of this app.
Thank you in advanced, sorry to be vague.

You should be able to restore factory settings by flashing the Samsung stock ROM using the official Samsung tool named Kies. The procedure is explained here. Your device name should be Samsung Galaxy Avant G386T.
Alternatively you can try Odin. The procedure is explained here. You must be aware that Odin is not supported by Samsung. Using it incorrectly or flashing an incorrect ROM (for instance a ROM intended for another device) can brick (permanently damage) your phone.

10 months later I finally got around to actually doing this and I'm having difficulty. When I attempt with kies, nothing happens. it gets to 100% and that window closes. then nothing else happens and I'm back to square one. any thoughts? thank you

Is there any log file from Kies you can post here?

And did you have any success with your attempt to factory reset your phones?

Terminal Emulator Problem Mac Spoof
I'm trying to do a Mac Spoof from my Motorola Moto E (Rooted of course!) but I have a problem cause i'm quite sure i'm not succeeding in spoofing!
Well, I installed BusyBox and Terminal Emulator.
Then I go to Terminal Emulator and wrote:
"su"  (so I have permission from SUPERSU)
root@surnia_umts : /  # **busybox ifconfig wlan0 down**

root@surnia_umts : /  # **busybox ifconfig wlan0 hw ether [New Mac]**

root@surnia_umts : /  # **busybox ifconfig wlan0 up**
root@surnia_umts : /  #

Then the terminal doesn't say anything else.
After that,  the wifi from the device doesn't work anymore ( I have to disable and renable the wifi to make it work again) and of course the mac didn't change...... anyone has an idea, need some help, I am new of Android!!!

It appears that Android MAC Spoofing can only be accomplished on "Open" access wifi networks. Try to change the last three sets of numbers from the original mac address. The first three sets identify the adapter/manufacturer, changing them may cause authentication issues.

Deleted my default keyboard program and I no longer have a keyboard?
I downloaded a keyboard-changing app, but as I used it, everything crashed, so I deleted it from my phone. Bad choice, since the app I deleted was my default keyboard. Now I have no keyboard, and I can't access the "Current keyboard" tab under Language & Input. How do i get my keyboard back?

You should sideload one from your PC and install it via adb or a file browser.  You can download the Google Keyboard from here for example, and should then copy it onto your device to somewhere accessible with a file browser.  You may need to enable Unknown Sources on your device before browsing to the .apk and installing it.
If you don't have a working file browser you will need to install the SDK Tools and enable USB Debugging on your device (first enable Developer Options by tapping the build number under Settings → About seven times).  Then from a shell/command prompt on your device you can run:
adb install path/to/downloadedkeyboard.apk

You can install the Google keyboard from Google Play. If the Google keyboard is already installed but broken for some reason, you can try Google Japanese Input. It comes with an English keyboard.

Kindle Fire 5th Gen Play Store Problems
I have a 5th gen Kindle Fire running 5.0.0 version of FireOS. I'm trying to use the April 6 Version of RootJunkySDL supertool to root the device, remove lock screen ads, and install Google Play store. The problem that I run into is with the Google Play Store. Once I input account information, I get the RH-01 error on the store main page. Additionally, I get the "An application requires an update requested by google play services" notification.
I've tried many of the online resources for fixing the error, forgive me for not being able to locate the most comprehensive resource I've found so far. The resource I used included 8-10 different methods ranging from clearing the cache of the Play Store and Google Services Framework apps to logging in via browser to your account and trying to install a random app.
My procedure is as follows (from a factory reset device running FireOS v5.0.0):

Select Language
Set up WiFi
Device downloads software update to 5.0.1
Log in Amazon account
Supertool Option 6: Root your device. Reboot.
Supertool Option 2: Install Google Play Store
Input google account
Error retrieving information from server. [RH-01] AND "An application requires an update for google play services" notification.

I've been through this several times in various sequences. Has anybody gotten it to work. What problem am I running into? I've chased down troubleshooting for hours.

Delete Known Wi-Fi networks
It seems someone, somewhere has removed the option to view remembered WiFi Networks in 6.0 (Marshmallow). I'm not sure if Android removed this feature, Samsung did, or Sprint did. How do I remove a remembered WiFi network if I'm not in range? This is for a Sprint Samsung Galaxy S7 Edge with Android 6.0.1.
EDIT: Please also note that I do not wish to root my device to remove WiFi networks as I know that is possible.

Related: http://android.stackexchange.com/questions/141760/how-do-i-forget-an-out-of-range-wi-fi-network-on-a-galaxy-s7

Why wasn't that marked as a duplicate of mine as this question was 6 hours before that one?

I guess I can see why it wasn't. I'm asking for a non-root solution.

Must be a handiwork of Spring or Samsung or both since stock Android M supports removing any saved network. It however allows only when Wi-Fi is enabled regardless of being connected to an SSID. When Wi-Fi is enabled, clicking the three dots line gives the option "Saved networks". From there I can remove any saved network.

How to enable Google Play on the Gionee M3S Android phone?
I recently purchased a Gionee M3S Android phone. It came with Google play on the home screen, but when clicked, that just pops up a white box briefly. How do I enable Google play on this phone?

Here's what I had to do to get it working (after several failed attempts):

On the M3s, I searched for "google play services apk mirror", and went to this URL: http://www.apkmirror.com/apk/google-inc/google-play-services/
Selected the most recent version (in my case 8.7.03)
Chose the 8.7.03 (2645110-246) (arm64+arm / Android 5.0+ / 320dpi) version. The important thing here is the -246 at the end, which targets the M3s hardware.
Downloaded and installed the APK. Allowed untrusted app to run.
Followed application prompts to setup the app, then ran Google Play.

Now Google Play works and can download apps, etc.

WhatsApp end-to-end encryption
Earlier this week, I saw below message on WhatsApp
 (Click for larger Variant)

What does this means to the User?

With end-to-end encryption, messages are scrambled as they leave the
  sender's device and can only be decrypted by the recipient's device.
  It renders messages unreadable if they are intercepted, for example by
  criminals.

My question is: Does this end-to-end encryption applies to individual chat and to group chat between Android-only devices or it also works on other platforms, Since WhatsApp is available on iOS, Windows Mobile also.

It appears to be between all platforms, as its written here:
https://whispersystems.org/blog/whatsapp-complete/
"Over the past year, we've been progressively rolling out Signal Protocol support for all WhatsApp communication across all WhatsApp clients. This includes chats, group chats, attachments, voice notes, and voice calls across Android, iPhone, Windows Phone, Nokia S40, Nokia S60, Blackberry, and BB10."

is that a official WhatsApp site? I guess we need reliable source to confirm on this Q!

https://www.whatsapp.com/faq/en/general/28030015  This may lead a bit further, but still no "they say exactly that" though. But actually for me its quite clear now. Where should be the sense in making this feature platform-depended?

Whatsapp End-to-End encryption includes chats, group chats, attachments, voice notes, and voice calls across Android, iPhone, Windows Phone, Nokia S40, Nokia S60, Blackberry, and BB10.
The idea of End-to-End encryption is to make a communication more private (like Face-to-Face Conversation) that is when you send a message, the only person who can read it is the person or group chat that you send that message to. None can see that message which includes cybercriminals and hackers. Because the End-to-End Encryption means the content of communications are not stored in plaintext on WhatsApp’s servers. Nor is the company able to decrypt users’ messages to access them since it does not hold the encryption keys. So WhatsApp will be unable to be compelled to hand over messaging data — even if served with a warrant by authorities demanding access.
This is applicable to the Users running the most recent versions of WhatsApp on any platform now get full end to end encryption for every message they send and every WhatsApp call they make when communicating with each other.

There are other attack types for non-encrypted messages, such as MiTM attacks. Since end-to-end encryption prevents this technique, I think you should mention this in your answer.

Unique signal problem - No one heard of such problem
I am using honor 4x from past 1 year. From last week I am facing a unique issue.
SIM 2 signal is not working with Vodafone in some areas of the city (for example it will not work in my home). Vodafone Signal is perfect with other mobiles in my home. Same Vodafone sim is working perfectly when I go to office (just 3 KM away from home). I tried to swap SIM-1 & 2. My BSNL SIM works normal either in SIM-1 or SIM-2 slots.
Following things I tried.
Put Vodafone SIM in SIM 1 - Same problem.
Tried some other Vodafone SIM - Same problem.
Put the Vodafone SIM in another mobile - Works perfectly.
Calling to that Vodafone number while in home - Message says "Seems you dialed a wrong number".
Changed the Vodafone SIM for same number - No luck, it wont work in home.
Experimented with lot of setting changes - No luck. It works, without any settings changes it works normally in my office.
Called Vodafone call center - No use, they never heard such problem .
Can any one suggest me what could be the problem.

Appears to me it is a tower linked problem-the one you are connected to while at home. Probably it is maxed out in capacity - you can check if others in neighborhood also face this problem and complain to service provider if they do. If it is only you..I have no idea why it is happening

Set Home button to reject calls
I had an android where i could reject calls with the home button. Default behavior in lock mode with unanswered call.
With my new phone that doesnt work anymore.
I can see the option to set Answering calls with the home button.
But  I want the opposite action.
When the phone is in the pocket and i need to immediately reject a call when i forget to put the device in do not disturb mode, the only button that solves that issue is the home button.
Is it possible to have the home button set to reject calls ?
SAMSUNG S7   (NOT rooted)
EDIT: I tried using tasker, but there is no Home button event condition.

This could be possible using an automation app like tasker (not tested, so just a comment with this hint): Condition = incoming call + home-button tapped, action = hangup.

sounds like a good idea,  except i cant find the Tasker hardware event HOME button

Ouch, yes: that's probably not there as it's no "hardware" button but a soft-button – didn't think of that. But is "swiping left" to reject the call so much more difficult?

I was hoping to do so in the dark so to speak, without removing phone from pocket.

Ah. If it weren't for "in the pocket", an alternative would be an app like Air Call-Accept where you simply accept/reject calls with a hand motion over the proximity sensor. I don't know about other options currently, sorry.

How can I un-brick my OnePlus One?
While installing a custom ROM on my OnePlus One, I accidentally wiped the INTERNAL STORAGE of my phone, thus wiping the zip files of the ROM and Gapps.
So I'm stuck with only the recovery, but no OS.
Upon reboot, the screen is stuck one the OnePlus logo.
I've tried using adb push and adb sideload but 'adb devices' does not recognize my device. However, fastboot does recognize it.
How do I install a ROM and get my phone to work again?

Hope this helps
Un-brick Oneplus One

Seems like your device is stuck in its boot loop. From XDA developers, try this. Might help.

Download a ROM that's specifically for your device, then connect your phone to the computer and use fastboot update <path/to/your/file.zip> to flash the package.

You've asked the question 15 days ago, did you manage to get your device working again? What steps did you take? I'll give it a go in case anyone needs it.
As I've experienced, having a USB OTG cable laying around can be most useful with this device. You can find them cheap just about anywhere. They convert any USB storage device you have to external memory for your One. Just connect it to your device and mount it in TWRP (or any recovery that supports it). Don't forget to unmount it or you'll run into trouble later on.
It does sound like you didn't get the drivers right if no device popped up with adb. You can install these generic Samsung drivers to make it work.
Another thing, if you're having issues in TWRP, it could be useful to flash a different version via fastboot. I'm using this one on my OnePlus One to flash Resurrection Remix M and it hasn't let me down yet.

Belkin mobile wireless keyboard F5L175 set to wrong language on galaxy tab e, how to fix
After pairing my galaxy tab e to Belkin mobile wireless keyboard, everything worked fine. The second time I connected a screen came up asking me to set language. Apparently I picked incorrect English US option because it now types some letters different than keyboard. How can this be fixed?  Can't find any reference to a setting anywhere on tablet. Thanks

Here’s how to set things right. First, turn on bluetooth on your device & connect to the external keyboard. On android device, you need to go into the Settings menu, then find the ‘Language & input’ option. (On recent versions of Android, you should see a ‘Select keyboard layout’ option in your notifications, which will take you to the same place.)
From here, find your Bluetooth keyboard listed under ‘Physical keyboard’ and press on its name. A menu will appear that lets you choose a keyboard language. If you don’t see the correct option, choose ‘Set up keyboard language’. Then, find your desired language (e.g. English – US android) and tick the box. Now your Bluetooth keyboard should be set to its desired language.
Thanks to the guys at MobileFun.uk

What are the implications of an old Android version?
There have been various bugs and security flaws found in different versions of Android. Many have been pached in newer versions, but the non-updated devices remain bugged/vulnerable.
My questions are:

Are all Androids with the same version bugged/vulnerable in the same way, e.g., does a Samsung running 4.0 have the same problems as a Sony running 4.0 or as a Nexus device running 4.0?
Is there an overview somewhere what bugs (and especially which security flaws) are there in which versions? Many devices sold today do not run the newest Android; can I tell before buying which bugs/security problems I might encounter? (I am not interested in missing features introduced by newer versions)

Just to make it clear: bugs that can be solved by updating some apps are not relevant. (They are relevant if the update solving the issue would require a newer Android version).

This question cannot be answered in general. Android is open source and therefore can be modified by the mentioned enterprises. These enterprises will be based on the same "stock | untouched" Android with many of the same bugs and "vulnerabilities".
But:

Nearly all enterprises are modifying Android (interface, core) to match their wishes (e.g. Samsung TouchWiz, Sony XperiaUI, etc.). They are changing they way the software works, causing or eliminating bugs and security problems. So it's possible that some problems are fixed/caused by enterprises themselves. Therefore it's not likely for them to have exactly the same problems.
There is no official list of security flaws available. But there is an official bugtracker: http://code.google.com/p/android/issues/list

How do I "forget" an out-of-range Wi-Fi network on a Galaxy S7?
I want to remove old saved networks that are no longer in range. I can forget visible networks, but out-of-range networks are not visible anywhere so I can't do the standard long-tap => "Forget Network" action.
There is no option for "Saved Networks" or "Manage Networks" under the built-in Wi-Fi app's "More" menu.
I have tried a third-party app, WiFi Manager, where the networks are visible but reported an error on forget:

Android 6 allows apps to change (edit password, forget) only those networks that were originally "created" in same app.

I quite distinctly remember being able to view saved networks on previous Android phones...

My phone is rooted, so methods requiring root are acceptable, but it's better if that's not necessary.

I have an Australian (CSC XSA) Galaxy S7 Edge (SM-G935F).

Apparently this was a problem with the S6, where the 'solution' was to use third-party Wi-Fi management apps that no longer work in Marshmallow.

http://forum.xda-developers.com/galaxy-s6-edge/help/how-forget-range-wi-fi-networks-t3137257
http://forums.androidcentral.com/samsung-galaxy-s6/596840-how-do-i-forget-saved-wifi-networks-when-they-out-range-samsung-devices.html
http://forums.androidcentral.com/samsung-galaxy-s6/567924-how-do-i-remove-saved-wifi-other-locations-my-samsung-galaxy-s6.html
http://ericscorner.blogspot.com.au/2016/02/how-to-remove-out-of-range-wifi.html

But that no longer works, as per the error message above...

Looks like this was (re-)added sometime between the initial release and the Android 7 Nougat update!
From the Wi-Fi menu, go to Advanced (top-right corner) and then the Manage networks option near the top of the page. You'll get a list of known networks and the ability to edit/delete them, even when out of range.

The method described in this answer does not require root, but it does require that you have a Wi-Fi access point ("router") you control.

One possible but very tedious and hacky solution is to host the SSIDs on a Wi-Fi access point you control, so that they are visible on the S7. Then you can "forget" them through the normal Wi-Fi settings page. The list of saved SSIDs can be retrieved (but not altered directly!) with third-party Wi-Fi management apps.
Having an access point capable of hosting "guest" networks/SSIDs is particularly helpful here. Otherwise, you'll need a wired connection so you don't kick yourself out by changing the SSID around.
Of course, this is quite a terrible solution in every way except that it works. So hopefully someone will have a better solution available.

As your device is rooted, you could directly edit the /data/misc/wifi/wpa_supplicant.conf file and remove the networks there. The block for each network looks like this:

network={
        ssid="network_ssid"
        psk="secretpassphrase"
        key_mgmt=WPA-PSK
        priority=1
}

Remove the blocks of the networks you want to get rid off, save the file, reboot – and they should be gone.
For app-based solutions, be welcome to check my list of apps for Global WiFi Configuration. Super WiFi & Internet Manager e.g. claims one of its features being: Single click to remove wifi network which has not been used since a long time or you wish to remove the one.

Hm. That seems to have worked, after a restart. Would be good to have a non-root method though. I'll accept this one later if no-one comes up with one.

Ok... so... "Super WiFi & Internet Manager" was both utterly broken and full of ads... today I was reminded that fullscreen video ads with audio are a thing, and discovered that an unskippable delay is also a thing. Anyway, back on point: thanks for the suggestions but I guess I'll stick with the root method for now. Open WiFi Cleaner looks like it might work and be helpful for those who use public wifi more than me.

If Open Wifi Cleaner does that job, please let me know – that was the app I had in mind originally, but it didn't seem to fully fit your issue (as it only says to be working for "open APs", forgetting them on disconnect). Wasn't aware of the "ad infection" of the other app – so I'll happily replace it with the FOSS one in my answer! Thanks for the feedback!

A notice: No reboot is required.

Found the only way to reset the saved network settings after searching for 2 hours on forums.
Go to Settings.
Go to Backup & reset.
Now tap on the “Network settings reset” option.
Hit the “Reset Settings” button.
You will be given another warning, hit the “Reset Settings” button again.
Your welcome!

Cool, resetting network-specific settings is a good idea. Didn't know you could do that.

I figured it out. You're all over complicating it. Go to settings backup and reset and then reset the network and connection part. It'll ask for your pin. Then it clears it all out

Would that not also clear out networks I do want to keep? Though it is another option for those happy to re-add wanted networks.

Settings, Data Usage,Wi-fi, More, Restrict Networks, then select from the list the ones your phone has accumulated which you no longer wish to access.

This one does let me see networks but there does not seem to be any way to delete them. Long-tapping did nothing. The "restrict" option only prevents background data on that network but does not forget the network.

5 years on -- Android 8 now has a Wifi advanced setting entitled "Manage networks: Manage your saved Wi-Fi networks" ... look ma no root!

How does boot animation affect booting time. And how can I decrease the booting time?
What if I load a lite boot animation in my device.
Does is decrease the booting time?
And how to decrease booting time as well as improve my phone's features.
device: Samsung Galaxy y duos GT-s6102
OS: custom ROM XDV3 by XDA Developers

BootAnimation doesn't affect boot time. It's just a series of pictures shown in sequence to you, while your phone is ready to give you the GUI.
There is no one certain recipe to make your phone boot twice as fast. Check this and this for possible solutions, to make your phone boot up faster

"For a faster boot it is better to avoid or use a shorter boot animation. The bootanimation.zip can be tactically placed on the best file system for optimum performance."  Is it?   And what do you think about editing the file  'system -> build.prop' as described at  link

Yeah this build.prop edit might help you out. Use an app from the store to edint the build prop, as hopefully they won't change the permissions of the file. I use Kernel Adituor (ROOT)

I have rooted my device and currently using custom room, did it with ES-File Explorer

How can I stop adverts from "System Update" from showing up on my lockscreen on a Micromax phone?
It's been quite some time since I last used Android, but following the untimely death of my old "roaming" phone while travelling in India, I've just ended up buying myself a Micromax Q338. This runs a Micromax modified version of Android 5.1 Lollipop
After uninstalling or disabling a few of the annoying apps it shipped with, I'm still faced with one issue - adverts showing up as notifications on the lock screen, which seem to turn up when / just after connected to the internet. If I touch and hold on them, they show as being from System Update, as shown here:

Lockscreen / Notification settings (click images for larger variants)
As far as I can tell, System Update is an official component, and not a third party app. As such, I don't think I can/should uninstall it. I also can't find System Update under Settings / Sound & notification / Notification / App notification, so I can't apparently disable them that way.
So, how do I stop System Update popping up adverts on the lock screen when there is / has been internet?

I'm 99% sure it's one of your apps that you have installed doing all the advertising. And one that didn't come from google play store as I do believe they forbid this kind of advertisement. What you can do is DL astro, backup all your apps and start removing 10 at a time, to figure out which one is the source. When such thing happens to me, it's usually one o the latest apps I installed, but it's has been doing this for you, for some time so ....

@ИвоНедев I've had the phone less than 24 hours, and it's been doing this since the moment I connected it to the internet, before installing anything (and I've only installed a couple of apps). So, I'm 100% sure it's not something I've installed! though I could well believe it's something that Micromax "helpfully" bundled into their build...

You could give one of the Filter/block notifications apps a try. // Was the device new or did you buy a used one? I tend to go with Ivo here that it could be a third party app posing under the name "system update". If it was a new device, I'd approach support and mention this kind of ads violates Google's TOS (though those apply to apps on the Play Store, mentioning it might have some effect).

@Izzy Bought new. Is there any way to confirm / check what app is actually behind that notification / notification name? The Micromax Support site just directs you to a local service centre, so not sure I'll get much help/luck turning up at one of those and mentioning Google's terms of service...

If you tap the "i" (go to app details), you might be able finding additional details. The package name would be helpful here. Also check with other apps from the page I've linked, some of them might offer additional insight as well.

@Izzy Clicking the "i" takes me to a rather unhelpful looking page under "App notifications", screenshot added. I'll try some of the apps listed for notifications. Also, should I ask a new question on how to turn an app name on the lock screen into an application?

Glad to see you already figured (including the formatting for images ;) So issue solved? If so, you might wish to "accept" your answer (thanks for sharing!) by clicking the check-mark next to it – which makes it identifyable as "solution" for other affected users. Thumbs up!

@Izzy Sadly I can't accept my own answer for 2 more days... The image formatting was all new to me, despite having been around on Travel.SE and SO for quite some time, so I've learnt both Android and SE things today! Thanks for your help pointing me the right way :)

I had the same issue, but I generally use a Mobile Data connection, so all I had to do was disable Background Data for System Update, and I stopped getting the notifications. Won't work for a Wi-Fi connection, though.

Thanks to help from @Izzy, I've figured it out. Annoyingly, Micromax have bundled something calling itself System Update that is set as a System Component and is generating these adds
To find out what's going on, I followed Izzy's suggestion on trying some Filter/block notifications apps. Took a few tries, but one of them (Notification Block(DND Notify)), when showing System Apps, showed me this:

(click for a larger version)
From that, we can see that the App calling itself System Update which is defined as a System App has the package com.rock.gota . A google for that shows many other people complaining about getting adverts on their lock screen from this app which their phone manufacturer had "helpfully" bundled into their base Android Image, just as Micromax have done :(
As I don't have a rooted phone, I couldn't use that tool to disable the notifications. Instead, I headed to Settings then Apps, discovered I could swipe right a few times to find All (wish I'd known that before!), scrolled down to this annoying System Update spammy advert app, and did a Force Stop. The Disable button is grey'd out, see How can I disable a stock app that has its Disable button greyed out? for how to get rid of an app like this now it's identified.
So, Micromax users beware - they're bundling spammy advert apps into their Android system builds :(

Blocking or deleting a sent message
Please advise urgently on my below problem?
I sent a message to a contact in error at 16:11. Apon realising this i noticed only 1 tick next to the messages. I then blocked the person,switched off my data,switched of my device, took out my sim and even uninstalled watsapp.
How will i know whether the person has read the message or not?

If the message shows one tick in Whatsapp then it is already too late. The contact will receive your message when they open their Whatsapp app on their device.
If you had turned on airplane mode whilst the clock timer was visible on the message then the message wouldn't have been sent, and you could have deleted it to prevent it from leaving your device.

How to prevent disabling of apps
All my searches on this topic just return results about how to disable (built-in) apps on Android, which is the opposite of what I want. I want to know how it is that some apps do not allow disabling or force stopping, and I want to know how to make that the case for certain downloaded apps. For example, Norton App Lock is supposed to prevent certain apps from being run on the device, but what good is it if you can simply disable Norton App Lock and then open any apps you want? I notice that some apps prevent force-stopping, and some prevent disabling. I want both to be prevented. This is for Android 6 Marshmallow.

If you have root, you move the app to /system/priv-app; privileged system apps can't be disabled through normal user methods.
Otherwise, it's up to the application to support Device Administration.  Apps like Norton App Lock should be implementing this if they don't already, since this kind of thing is exactly what it's designed for.  Registered and activated device administrators can't be disabled or uninstalled until they are deactivated.

Makes sense. So how do I prevent enabling and disabling of device administrating apps? Because currently I can do that just as easily.

@Moss You can only do that from the Owner account, and must obviously retain that ability.  If you're looking to prevent someone else who uses the phone from messing with this kind of stuff then they should have their own account and the Owner should have a PIN/password/pattern.  (Or just the latter if you want to prevent thieves.)

Hmm, the problem is that Lenovo phones don't allow multiple users, even in Android 6. I guess a restricted user account is what I really want.

What does exactly "Re-root System (SuperSU)" do to your phone in Philz Touch Recovery?
I tried to manually root my phone via pushing a proper su binary to /system/bin and /system/xbin.  I was able to push them via adb in recovery, which is a root one (idk why). Once inside my phone, I chmodded 755 both of them and typed su --install and su --daemon&. After that, I tried to setenforce 0.
All seemed to work, but when I rebooted, I wasn't rooted. So I returned to recovery, used the "re-root" option and it worked.  Why is this?

According to the source code available on GitHub, the recovery performs a whole bunch of operations aside from simply launching the daemon in background, copying the su binary to /system/xbin and changing its permissions. As can be understood by examining this install-su script, what the recovery does, is to initially perform a cleanup operation for root manager apps that may have already been installed.
After that, the operation of copying the relevant files, namely, the su binary (which is called anytime you request root privileges), the 99SuperSUDaemon (which execution depends upon init.d), a customized install-recovery.sh (to force the daemon to be executed on Jelly Bean) and SuperSU.apk (the root manager).
After this phase, the script uses the previously defined functions set_perm (which combines chmod and chown, and serves to define ownership and permissions) and ch_con (which marks the files as system ones). The latter is probably the cause of your manual procedure's malfunction: you didn't change the context of the files you pushed, so they weren't recognized as system files.

How to extract .backup files created by android stock recovery?
I'm using Coolpad note 3 lite, running Android 5.1. I created internal memory backup using stock recovery. Files were created in this format:

userdata_yyyymmdd_HHMMSS.backup  = 2GB
userdata_yyyymmdd_HHMMSS.backup1 = 2GB
n. ...
userdata_yyyymmdd_HHMMSS.backup5 = 1.53GB

Is there any way to extract the files to PC? I couldn't see file header mentioned here. Another user referred a method, which I couldn't understand.

Android 5.1
TWRP installed
Rooted
FAT32 internal & SD card.
Tried Titanium backup and it don't recognize the format.

Edit:

Tried to do a stock recovery backup and replace the files. While trying to restore stock recovery not showing SD card, although it takes backup in SD card during backup in same session.
7Zip Windows opened the merged .backup file. It shows "2.ext".

Mounting 2.ext in Ubuntu shows nothing even though file space is occupied.

When trying to open 2.ext using 7zip, I see lot of files in similar name and opening them in 7zip again shows again same file names....

Now how do I recovery files from this 2.ext?

@ManishRamavat No solution yet, I just run foremost in Ubuntu to recover my photos. That's not recovering great either.

this is solution for your ext4 image https://forum.xda-developers.com/showpost.php?p=73612779&postcount=58

As a first step, you will need to merge the various .backupN files into one by using the following command:
cat userdata_yyyymmdd_HHMMSS.backup* > userdata_yyyymmdd_HHMMSS.backup
It looks like the header size of 512 bytes is the same across many devices, so try to extract using the following command:
dd if=userdata_xxxxxxxx_yyyyyy.backup bs=512 skip=1 | gunzip -c | tar xv
If this doesn't work, you can try the other method as described in this post:

Download the simg2img tool from here.
Convert the .backup file into an image using command simg2img userdata_xxxxxxxx_yyyyyy.backup userdata_xxxxxxxx_yyyyyy.backup.raw
Mount the image using command mount -t ext4 -o loop,rw userdata_xxxxxxxx_yyyyyy.backup.raw "data".

You should now be able to copy the contents of the backup image.
Alternatively, you can download the simg2img binary along with the script that automates the above steps using the link from the above mentioned post.

Tried with Cygwin, unable to cat files (no space issue). Downloading ubuntu for VM and update the status.

First method didn't work because of
"gzip: stdin: not in gzip format
tar: This does not look like a tar archive". simg2img can't open the merged file. "Cannot open input file userdata.backup". Any other ideas? How to do with fallocate as another user mentioned?

@Jones Are you able to use md5sum? If yes, then try to issue md5sum -ve '1/1 "%02X "' userdata_yyyymmdd_HHMMSS.backup | head -n 10, then tell us the output. This way, we could try to identify the file type for you.

@DeathMaskSalesman - "md5sum: invalid option -- 'v'" I'm getting this error. Am I missing something?

@Jones No, it just means that your build of md5sum does not support the -v flag. You may want to skip the -e flag as well, and use md5sum -C instead. This will output both the hexadecimal code and its ASCII transliteration.

As an alternative to this manual procedure, you may also want to check if your Ubuntu distro has the file or the magic command, which are able to identify files by examining their header.

@DeathMaskSalesman - Used file with c flag. No patterns found.

@Jones Then we should perform an hexadecimal dump in order to manually analyze the file.

@DeathMaskSalesman - Now I'm able to see the internals of backup, although I couldn't retrieve anything yet.

https://android.stackexchange.com/a/137339

stock android recovery extracted files can be restored with nandroid custom recovery, if you simply repack them into tar archive.
i put this two command lines in a dirty shell script (extract + repack as tar).

Text Bubble and Background S6 Marshmallow Update
Ever since the update, my text background is white and the bubbles are yellow and blue only. I have no settings area like before where I can adjust it. I can change the background but that's it. I can't adjust or change the bubble or its color? It's really hard on my eyes. Is there a way to chsnge them still or do I have to download a theme? Seems silly to chsnge the theme for a text bubble option!

I have an S5, S4, and Note 2, and I also got fed up with the Stock Messaging app.
I highly recommend using Textra SMS. It has about 250,000 good reviews, many of them from Samsung users.
It's not one of those apps that use data and give you a separate phone number, Textra is a replacement stock SMS app with major customization.
Here's a screenshot of the feature you seek:

I have mine set to AMOLED-friendly black since I use Samsung, and I also enjoy the "Send Delay" feature for all the times I need to fix typos after hitting send.
Hope this helps!
Affiliation: App User

This is because the update now has "enhanced messaging" (you can turn on under message settings). This is just like the iMessage that the iphone has. When other android users turn this on the text colors will change and you'll be able to see if they've read your texts or not and vice versa.

Are you serious?! How did you find out about this? Post a link?

ADB Debugging over wifi not connecting
So I am trying to connect my device to adb over wifi. I have been following this tutorial
http://codetheory.in/android-debug-bridge-adb-wireless-debugging-over-wi-fi/
I have been doing this
adb tcpip 5556
adb connect <ip address>:5556

what i get back is
cannot connect to <ip address>:5556:5556

if i do not include the port
adb connect <ip address>

then i get this
cannot connect to <ip address>:5555

Does anyone have any  ideas?

Maybe adb tcpip 5555 if that's the default.

Does the device have to be rooted to do this?

No, not at all.

Is the device reachable in the network? Can you ping it? Is the IP address correct? That error shows up when I can't reach the device due to its Wi-Fi being disabled/ a firewall in Android is blocking the connection / IP address is not of device.

So I think the problem had to do with the network I was on. When I moved to a different network I was able to connect.

Please help

Booting into recovery and doing a factory reset is pretty much your only option.
To get into recovery:
Press and hold “Volume UP + Power + Home” button together and as soon as you see Galaxy S7 Boot logo, release all three buttons.
When you see an exclamation mark on screen, press and hold Power button and hit the Volume Up button once.
Then select factory reset and go thru all the setup again..

Which one to install- 32 bit or 64 bit kernel?
Although I'd flashed my phone with new ROMs several times, I've never tried flashing the kernel before. When I searched for a custom kernel, saw 32bit and 64bit  version. So how am I supposed to choose this?
My phone is YU Yuphoria running on Ressurection Remix v5.6.5 (Marshmallow official build). Please tell me the best kernel for it.

Do you have a command line app installed?

Nope. I don't have any of them

In this case, I'll recommend you to install a terminal emulator. Once you do it, you'll be able to use the uname -a command, which will theoretically output a bunch of info about your device, thereby included the processor type. Once we have such info, I think we'll be able to help you discern the correct kernel for your architecture.

it shows CyanogenMod (mine is resurrection remix ROM) -dates etc-  arm81

Well, then: ARM v8.1 is a 64 bit architecture.

By the way, remember to make a Nandroid backup. Should the flashing go bad, you'll lose nothing.

How to fix broken images in gallery?
I am using Celkon Q54+ running Android 4.4. When I copy some JPEG images from my computer to my phone via USB Storage mode, those images are displayed as broken images in the Gallery app.
I have tried clearing the data for the Gallery app. I have also tried installing third party Gallery Apps like QuickPic from the Play Store. No app seems to detect my photos. But the photos are looking fine when opened from my computer.
How to fix this?
Edit: Only HD images shot with DSLR cameras are not showing up in gallery. They have resolutions of the order of 5000 pixels. Images of resolution less than or equal to 1600x1200 are perfectly displayed in Gallery.

Are Cyanogenmod nightlies compatible with latest vendor images?
I am about to install Cyanogenmod 13 nightlies on my Nexus5x and was wondering how I can find out which vendor.img is required for which nightly?
thanks!

Can you just use this guide to install CM13? https://wiki.cyanogenmod.org/w/Install_CM_for_bullhead.

@SuperThomasLab: if i follow this guide, then i get an unrecoverable error message at the first boot saying that there is a mismatch in vendor image.

Why not just download the latest vendor.img then from here: https://developers.google.com/android/nexus/images#bullhead and flash it with ‘fastboot flash vendor vendor.img

thats exactly what i did and this leads to the error. thats why i am asking which vendor.img exactly i need. cause it seems its not the latest.

You generally need the latest vendor image but since we (CM), unlike Google, support all CM13 devices using the same code branch the build number you see in Settings -> About doesn't always match up with the build number you see for the stock images.
Solution: Run 'getprop | grep fingerprint' on a terminal on the device or via adb shell. From the output, compare "ro.build.fingerprint" and "ro.vendor.build.fingerprint" values. Those must match for the message to disappear.

Will Google Play Services work on Yun OS phone?
I have this Chinese Phone which is a Yun OS, I've tried all different types (Architecture, Android Version, Screen DPI) of Google Play Services from APKmirror site but all goes "Unfortunately, Google Play Services has stopped".
My phone is also not rooted. Tried many root apps (kingroot, kingo, etc.) mobile/pc but no luck.

TL;DR answer: It won't work.
Google Play Services relies on several apps and libraries to reside in a few different system directories, you can't just "install" Google Play Services, you need to flash them into your system with a 3rd party recovery like TWRP or CWM Recovery. The gapps are available from OpenGapps and other sources.
Although a little research tells me that Yun OS is NOT Android, although it is based on AOSP.

According to Google, Aliyun (YuOS) is a forked but incompatible version of its open-source Android operating system.
Yun OS incorporates its own virtual machine, which is different from Android's Dalvik virtual machine.

Source

And some searching also show very few, if any, people who have gotten the Google Play services to work, probably the biggest reason is YunOS uses a unique VM that is not Dalvik or ART, therefore it will not work.

How can a rooted Android phone generally get bricked?
I've rooted my phone but now I'm scared that it would be bricked. I've seen a page on "Tips to prevent from bricking" and it said to install custom ROM recovery or something like that. I think there were two things; ClockWorkMod and Team Win.
I tried to install one and downloaded ROM manager but didn't work (didn't find my device model name).
Doing what kind of things increases the probability of bricking my device?

Why did you root in the first place ?

Curiosity, Internet pressure and someone saying "OMFG, ROOTING IS THE BEST THING I'VE EVER KNOWN". It's pretty cool actually.

It's good but in most cases you don't even need root.

Doing exactly what you are doing is probably the biggest chance of bricking your phone - experimenting without proper knowledge and understanding of how things work. Go into xda-developers and find your phone's forum. Then start reading - how to install a ROM and a Recovery, change kernels etc. Read the threads and follow the steps exactly as they are shown and you won't be having any problems. All it takes is for you to mess up a single step, to brick your phone - may it be you download wrong file, not for your model or you type in wrong command etc. Still Android these days (not like back in 2010 for example) are quite resilient. It's not too difficult to recover from almost all kinds of bricks.
TLDR Read how other people did it before you on accredited sites like XDA-Developers and be careful.
Story time: I've been doing this (rooting, installing roms etc. - being power user)  for 5-6 years now so I know my stuff. I started unlocking my LG G4, then rooting, then installing recovery. What I did here was really stupid. Instead of installing a recovery I booted into it - so I had access to it only once. But I didn't notice right away. I installed my files, and the installer required a restart, and to boot back into recovery. But since I didn't install recovery the first time, as soon as I restarted my phone I literally messed up. I went into semi-soft brick. No access to fastboot, couldn't hook up my phone to my PC to execute commands, and the phone was in bootloop, only going as far as the logo.
Well I panicked a bit, went into the forum and started reading for solutions. At the end, something written for totally different thing allowed me to push some commands, and salvage my phone.
Also on your comment: And in general, don't root if you don't know what it is. Many people do root exactly for your reasons "people say its cool" I rooted to install xposed and get some modules I need.

Short, straightforward and precise answers, please.

@rjt.rockx I have bolded the TLDR section just for you. OP might be able to benefit from my personal experience story ;)

Excellent example, sir. Although I prefer a more empirical approach (and bricking things is what you should go through in order to learn how to fix them), it's generally better to learn from others' mistakes. Of course, this doesn't stop me from messing with the bootloader, but reading is a must, and something to do -before- playing with something you don't know about.

Things like :

Flashing a recovery/ROM that is built for a different device other than yours
Installing beta/unstable builds of ROMs/recoveries
Messing about with system files without a proper backup
Typing the wrong command while modifying your device

These increase the probability of your device getting bricked.
Always ensure that you have something to fall back onto in case of an error. A NANDroid backup is recommended.
In case you run into any problem, sites like XDA-Developers are a good source of help.
Rooting isn't bad, as long as you know what you're doing.

Actually, I've just downloaded some apps like xposed, system app uninstaller, gravity box, tinted status bar and apk2rom. I've downloaded them to modify the appearance. And I've changed the boot audio and animation, also deleted the camera sound nothing much.

@BenJunior As long as you know what you're doing, nothing much won't happen. But sometimes, conflicting modules might cause soft bricks.

Can downloading some modules from other websites other than Google Play be dangerous?

@BenJunior Nope, nothing like that. There is no guarantee that those modules might be malware-free, though. Google checks the APKs uploaded to the Play Store, so there is a comparatively lesser threat level there.

Is it possible to unbrick without any recovery installed?

Is it also possible to still maintain these appearances like the transparent statusbar even after unrooting? Thanks

Nope, because Xposed requires root to function properly, and unbricking, yes, if you have a specific tool to do so.

Nexus 5 stuck at Google screen after failed(?) rooting
Our How to root Nexus 5 question has no answer, so I followed the most OK-looking Nexus 5 rooting tutorial on the rest of the web, all went well until the step that says:

After booting into recovery mode, tap the ‘Install’ button and then select the SuperSU ZIP file you had transferred

The trap is that on that tutorial, what seems to be a link to the ZIP file is actually a link to a page containing the real link surrounded by advertisement. So when I pressed "Save Link As" I actually downloaded some HTML rather than the real ZIP.
Realizing that, I wanted to reboot to try again with the real ZIP so I pressed "Reboot", it proposed me to install SuperSU so I accepted, happy to get it done quickly. The phone seemed to install something, then started to reboot.
PROBLEM: The following animation has been looping for an hour already and no sign that it will ever end:

QUESTION: How to correctly finish the rooting?
I am afraid that shutting it down now will brick the phone or something.

Shut it down, wipe the cache partition, and try booting it up. Nothing will happen.

@rjt.rockx: I shut down, started TWRP recovery, wiped to factory settings then wiped the cache, then launch system boot. After 5 minutes it is still on the same animation.

If all else fails, flashing a factory image from fastboot will generally solve boot issues. NB: If you do want to re-attempt rooting, that version of SuperSU is super old - it probably won't work. The latest (stable) version looks to be 2.65.

CF Auto-root (https://autoroot.chainfire.eu/) would be a good option to root again after booting up.

This solved the problem:

Download the latest stable SuperSU, it is the ZIP file that can be downloaded at http://download.chainfire.eu/supersu-stable
Restart in TWRP Recovery mode
Press Mount
Delete the faulty ZIP and copy the right one instead (at the root of the filesystem)
Fixed! Now continue with the tutorial normally.

Thanks rjt.rockx and eldarerathis for the tips!

Internal memory of my Moto E is almost full even after uninstalling and disabling so many apps. Will rooting it out help? If yes, then how?
I feel that in 2-3 months my phone will stop even updating the existing very few apps. So I am thinking about rooting it. But even if I root my phone will I be able to do something to fix this internal memory problem? If I can fix this, then I am in need of the possible ways (After the root).

No... Rooting will not "help" reduce space usage, in fact it will require space for the SuperSU app. Have you checked our insufficient storage tags and wiki?

@acejavelin I have already rooted and flashed my phone with Marshmallow based custom ROM. Now I use adopted storage feature of marshmallow.

Sorry... Just popped up in my feed like a new post. Glad it's working for you

Entering recovery mode when plugging powered off tablet to charger
I installed Philz Touch 6.59.0 (ClockworkMod 6.0.5.1) in my Samsung Galaxy Tab 4 7" Wifi (SM-T230) and modified the /system/bin/lpm (also called playlpm in other devices) to reboot the device as soon as it is plugged.
The modification of the lpm file works great when I don't have Philz Touch 6.59.0 installed on the device. Every time the device is off and I plugged it to the charger, it starts Android just fine.
The problem comes when I install Philz Touch 6.59.0 which works great by it self but when I modify the lpm file, every time I power off the device and then plug it to the charger, it start in recovery mode which is incredibly anoying.
Next is my lpm file:
#!/system/bin/sh
/system/bin/reboot

Does anyone knows what can I do to solve this issue or change this behaviour?
EDIT
I also tried the TWRP and the same thing happens. When powered off and plugged in, the device starts in recovery mode.

I've no clue about this issue, although it makes me think about the jig device, which is a little electric circuit used to force the Download mode in a powered off device. Its mechanism is simple: it limits the voltage to a value which is interpreted as the value which triggers the booting in Download mode. I guess that the CWM modified some parameter in such a way that the voltage value in input triggers the Recovery, instead of the OS, but I've zero proof of it.

It was simply a problem of line endings. Somewhere along the road I modified the lpm file and the line endings of the file were changed to Windows and they were supposed to be to Unix line endings.
When you edit a file in a text editor make sure to the correct line endings. Next is a picture of how to do it in Sublime Text:

How to change locale and make it stay that way?
My friend has a LG V10 and unfortunately, it doesn't have the language he wants (Hebrew) as part of the stock ROM.
I've googled around and found that there are apps that enable you to change locale to more languages than the ones that are included with the ROM.
I've used one (MoreLocale2), and it works.
The issue is that the language is reverted back to default (English)
after the device is rebooted ;/
After seeing that I tried using other apps that work the same way, but they all seem to have the same issue.
Is there any way to change locale and force it to stay that way after a reboot ? ;/
I'm not really interested in changing ROMs, this isn't my device and I'm looking for a simple solution as I'm doing this as a favor.
Thanks!
