Network SIM unlock code not working
I paid to get an unlock code for my Samsung Galaxy S4 Active SGH-I537 locked to AT&T. I have tried to enter the unlock code given when the phone boots with my other carrier SIM card inserted, but get "Network unlock unsuccessful" error message.
I wrote to the company and they responded with the following instructions:

```<code>(Samsung Galaxy S4 Only)
Follow these step carefully, as long as you have the correct code it will work 100% (Your phone must be updated to the latest firmware!)
1. Make sure that the phone PROMPTS for the code with a NON accepted sim card and that your IMEI is correct by dialing *#06#

a. Go to the Dial pad and dial *#0011#
b. Please click your MENU button (Bottom LEFT button) and click BACK on the menu that appears, Nothing will happen do not worry please move to the next step
c. Please click your MENU button AGAIN and this time click KEY INPUT
d. When the Key input box appears please input the number "1" and hit OK
e. You will see a number 1 for a while, please wait until it changes into the SERVICE MENU
f. Please click [1] UMTS > [1] DEBUGGING SCREEN > [6] Phone Control > [6] Network LOCK
g. You will see 3 OPTIONS within Network LOCK
h. Please click on number [1] Perso Sha256 INFO, the screen will change slightly
i. Please hit the MENU button then when the menu pops up please carefully hit BACK to return to the previous screen
j. Next Please click on number [2] Perso Sha256 ON, the screen will change again to a one line message
NOTE: If you see ENABLE_FLAG[1], refer to the notes below. If you see ENABLE_FLAG[0], proceed with step k.
k. Restart the phone on the screen by holding the power button and click RESTART
l. When the phone prompts for the unlock code simply enter the unlock code provided to you
m. Your phone is now permanently unlocked!
*If this is not working, go to Solution #2
*NOTE - If it shows ENABLE_FLAG[1]:
Press menu, select back to go back to the Network Lock menu.
Select [3] Perso Sha256 OFF, then select the first item after.
It will say "Menu not exist".
Press menu, select back, press menu, select back to go back to the network lock menu again.
Select [2] Perso Sha256 ON again, it should now show Enable_Flag[0]
You may continue to step k in the previous instructions.
</code>```

I cannot get pass step e. The Service Menu is inaccessible.

I write to them again and they send me the NCK Network unlock code along with the MCK Defreeze code and the following new set of instructions:

```<code>Try Solution #2
Follow these step carefully, as long as you have the correct code it will work 100%
1. Power off and on your phone with different network sim card. "SIM network unlock PIN" or "Enter Network Lock Control Key" screen will appear.
2. Type your Unfreeze code (MCK code) and hit Unlock button. You will get "unsuccessful message" again but don't worry.
3. Now type the Unlock code (Network or NCK code) and hit Unlock button.
*If phone say "Network Lock Succesful" it worked, but if not, proceed to step 4.
4. If you get "unsuccessful" again then hit Dismiss button and type *2767*3855# on phone keypad. (CAUTION! This will reformat all your data!)
5. After phone restarts, type the Unfreeze code (MCK code) when prompted to enter "SIM network unlock PIN" or "Enter Network Lock Control Key" screen and hit unlock button.
It will say "unsuccessful" again, don't worry!
6. Type the Unlock code (Network or NCK code) and hit Unlock button.
7. Your phone should now give you the message "Network Lock Successful"
</code>```

I tried it, but couldn't get past step 4. After I enter the code *2767*3855# , it doesn't do anything.

Ok, so may third time is a charm? No.

Latest set of instructions:

```<code>1.  Make sure that the phone PROMPTS for the code with a NON accepted sim card and that your IMEI is correct by dialing *#06#
a. Go to the Dial pad and dial *#197328640#
b. Please click on number [1] UMTS > [1] Debugging screen > [8] Phone Control > [6] NETWORK LOCK
c. You will see 3 options
d. Please click on number [1] Perso Sha256 INFO, the screen will change slightly
e. Please hit the MENU button then when the menu pops up please carefully hit BACK to return to the previous screen
f. Next Please click on number [2] Perso Sha256 ON, the screen will change again to a one line message
g. Restart the phone on the screen by holding the power button and click RESTART
h. When the phone prompts for the unlock code simply enter the unlock code provided to you
i. Your phone is now permanently unlocked!
</code>```

This time when I enter the code I am presented withe following screen but the options don't match up. I can not get into the UMTS MAIN Menu.

I have been given the Network unlock code, defreeze, provider and sub provider keys and none seem to work.

I am on Android version 4.3 and have never rooted and don't want to just yet. At least until the warranty expires.

Kernel version: 3.4.02-2244695

Recover data on a bricked Nexus 5
I bought a Nexus 5 just a few weeks ago and it died miserably yesterday without any apparent reason at all. I've read quite a few threads around the net about this and I haven't been able to power on the phone with the method suggested.

What I'd like to do now is trying to recover as much data as possible and/or wipe the phone completely [without losing warranty]. Is there a way to do so considering that:

connecting the phone to the computer won't work

I can't power on the phone in any way

I can't reach the boot loader

What I've tried so far:

holding the power button down for 10+ seconds

holding the power and the volume (+ and -, either together or one by one) buttons for 10+ seconds

did the steps above when disconnected from a/c, when connected to a/c and when connected to usb.

phone recharged for a 10+ hours and did again all the steps above

tried at different time of day with different stars configuration, swearing and being nice, swearing and being nice at the same time too.

asked the help of all gods I'm aware of without any luck (does this suggest google is evil?)

I'm looking for a way to update a file (override it if need be) on the SD Card from an email attachment with one click, sort of like a Batch file in windows.

We have 50 tablets at work and every now and then we need to update a price list file. Most of the users are not too bright and can't copy from the attachment and then navigate to the correct folder and then paste the file in.

I would like to know if there is any way to automate this like a batch file in windows, is it even possible.

All tablets are using 4.2.1 and are Asus TF300T and NOT Rooted. I usually email the updated file then have to spend 15 min with EACH person holding their hand to update it. Any help or direction to a thread with something similar would be very appreciative

How to avoid mute when adding new call
I'm on Android 4.2.1.

During a call, tapping 'Add call', automatically mutes the current call. I find it very annoying, mostly because usually when I want to add a call it's because I want to make a conference call.
Further more, sometimes I'm asking someone for a friend's number, when starting to type the number I'm muted, and the first one goes "hey, you're writing?". Very annoying.

Anyway is there a way to disable this annoying behavior?

问:
Android's Daylight Savings Time change messes up recurring events. How can I deal?
I've had this issue for a while now: Whenever the Daylight Savings time change occurs, Android takes it upon itself to adjust all my reminders forward or backwards one hour-- this happens in the stock Calendar app, my to-do list app (Tick Tick), and my alarm app (AlarmPad).

For example, I have a recurring alarm set to go off every morning at 7:00 am (except Saturday.) With the change coming on Sunday, my alarm app shows me that my next alarm (on Sunday) will go off at 8:00am, not 7:00. In Tick Tick, my recurring reminders after Sunday are similarly pushed 1 hour back.

This is something I Do Not Want. I want my alarms to keep going off at 7am every morning, and my recurring reminders to stay put. Is there any way to stop this behavior in Android?

(I'm on a Nexus 5 running stock KitKat, if it matters.)

Can't launch Google Now with swipe up from home key

I googled it and found that this may be what many people were looking for but I don't know why it started to behave like this.

I do find the swiping up from home button gesture useful for me to launch Google search but somehow it stop working. There usually should be a semicircle with 'Google' on top when halfway swiping up but what I get now is a search icon that function as it will launch last used app (if swiping gesture is done in launcher) or will do nothing (when gesture done in any app other than launcher). I did not disable Google Search, reboot didn't help, and clearing cache of Google search didn't help too.

I don't know what I did to get this as a result. Any clue on what's happening? Nexus 7 2013 stock kitkat

Android WIFI grey/blue icon (and performance) depends on AP?
I have a very peculiar issue with my Android Tablet.

Issue:
Tablet has good access to Internet and blue icon whenn connected to AP (access point) "A", poor access and grey icon with AP "B"

Hardware:
Ramos i9 Android 4.2.2.
Router/WIFI AP Zyxel P-2812HNU-F3 ("B" above)
Apple AirPort ("A" above)

Description:
I have the i9 since 2 weeks. After working flawlessy, since two days I notice a degraded internet performance. Tunein radios do not connect, internet page are slow etc and WIFI ICON IS GREY. The connectivty is not completely absent, it is just "slow".

With my surprise, my Huawei Y300 and other HW (iMac, iPod etc) all is working fine with my Zyxel. I did a try and turned my Huawei to WIFI Hotspot and connecting the i9 to this new WIFI, ALSO my i9 works nicely! (BLUE ICON etc etc)

I then connect my (old) AirPort to the LAN of the Zyxel, and configure teh Airport as a new WIFI. Surprise! If I connect the i9 to the AirPort all works! Notice the Airport has NO access to internet! The Airport has to go through the Zyxel!

Give the above I assume is something related to the "radio transmission" area. I then changed transmission channel and lowered transmission standard (from b/g/n to b/g) of my Zyxel, but still no result ...

Any idea? Thanks for helping me!

How to manually change default save location to phone storage
My phone Iocean X7S has opportunity to save apps to either internal storage, phone storage or external SD-card. However, I can't use phone storage as apps saving location. There is Phone storage and SD card opportunities in Settings -> Storage -> 'Default write disk' . However, whichever I choose as primary, there doesn't happen anything. If external SD card is mounted, there is "Move to SD card" button in apps and a tab 'SD card' in Settings -> Apps. If I unmount SD card, there disappears opportunity to choose primary save location, SD card tab and button to move app another location. However, there reads 'Phone storage app 0.00B' and 'Phone storage data 0.00B' in apps instead of 'SD card app and data' when SD card is unmounted. So I think it is some kind of software issue.

I have tried factory reset different ways without any result, there is still only opportunity to keep apps in internal storage or SD-card. In \storage\sdcard0 is external SD-card and \storage\sdcard1 is phone storage.

App for recording lectures
I am a mathematics graduate student looking for ways to improve my note taking. I have been experimenting with recording lectures with my Galaxy S5 (using Coji, which is a great app), but I am now on the market for something a bit more specific.

I want to be able to start the recording at the beginning of lecture, and take pictures of the board throughout class without stopping the recording. Some of the mathematics being taught is pretty hairy, and it takes some time staring at pictures of the board and at your notebook to get it. I would also like to be able to split the hour and a half long recorded file into smaller segments afterwards, say segments going over this or that proof. An app that puts this all into individual sessions (like Coji) would be a plus as well.

Does anyone have any familiarity with an app that has this functionality? I haven't had much luck finding something that hits all the key points.

Why is this happening? Is this a known issue?

What the heck is wrong with my photos?
So ... I got this puppy. And he's cute so I want to post pictures of him on the internet. I realize we could have a very long conversation about whether or not anyone wants to look at photos of my dang puppy, but I just want help uploading them.

I am pretty sure the problem is the photos -- but if I try to upload them via the Tumblr App, it fails silently (no post is made, no error logged). Text posts go up just fine. If I try to go through the browser, I get an error: error uploading photo that doesn't clarify much. If I email myself the photo and edit it in an editor I can post it but that's not a great workflow.

Has anyone else experienced this? Are there workarounds? I have an aging Samsung Galaxy S.

Note: I tried opening a few phone camera photos on my laptop (in ImageMagick) and I'm getting a weird error. It is basically the same for the three photos:

How to prevent android from auto-sync'ing gmail contacts and photos
I just got a Samsung Galaxy Note 3 and when I go into my settings then add an account and add a gmail account, it gives me an option to choose what I want to sync.

Android can't boot -- displays booting splash until battery drains
My Android can't boot.  It displays the booting splash (a sci-fi planet-like image) until the battery drains.

Is this condition what's referred to as a boot loop?  Is there any chance to recover?

The condition came gradually. Each new time booting, it would take longer but it would eventually boot. As of yesterday, it can't get through the boot step and just stays there until the battery is out.

Another thing that was happening in the last couple of weeks is that the phone would randomly (on its own, without user interference) go out (but not power itself off) for like 10-15 min at a time, pressing power wouldn't do anything, then it would wake up and the 4G service would be reinstated.

The hardware is a Motorola Razr Bionic.

I also tried going into the recovery mode but all it did was display an android robot lying down with a ! (exclamation mark) sign above it for a few minutes, then went back to the splash screen hanging again.

I also tried following these instructions (Alternate Method) but I am stuck in part 5:  I press volume up/down but it doesn't change the lying android with an exclamation mark.  Eventually, it goes into the infinite boot splash and I have to take the battery out to get out of it and power it off.


问:
Caller ID for forwarded calls
Let's say I have a fixed line phone, say 2xxxxxxx1. I have set this phone to forward all calls to my Moto G, say 9xxxxxxxx2. Now whenever I receive a call that was forwarded, I see two numbers in the caller Id. Say the original caller was 9xxxxxxxx3, then I see the caller id as 9xxxxxxxx32xxxxxxx1, i.e. the actual caller's number, appended by the number that forwarded the call to me.

I understand this can be a great feature to know the actual caller and the forwarder. But, it does not go well with the contacts and apps like True Caller. Also It becomes a pain to quickly save the received call to contacts.

Is there a way I could completely get rid of the forwarder's details from the caller id? Does it happen on all android phones? Is it specific to Moto G, or the OS it is running? Can it be carrier specific? Does anybody know an app that could override the default phone app and provides what I want?

PS: I am having a Moto G Dual Sim in India, running one SIM on Loop carrier, same issue when I tried a Tata carrier. The fixed land line that forwards to my Moto G is run by MTNL

Exchange Services and Android OS/System draining battery
I'm using Samsung Galaxy S4 with Android 4.4.2, for about 5 months.

I've experiences before some problems with battery, like sudden crashes when using apps intensively using graphics, but today the battery started to be discharged very rapidly, 10% an hour, or even more, without device being used. I've found out, that Android System and Android OS are responsible for that carnage. But after restart and charging the phone I've found out, that Exchange Services has also significant part in it.

After browsing internet I've found topis like that: https://code.google.com/p/android/issues/detail?id=37437 suggesting, that Android OS/System battery drainage is connected with Exchange Services. But that topic is very old, and people are writing about older version of Android.

Can this behavior be connected with the linked issue? If so, why it happened now, and not previously? Can the previous crashes of Android be somehow connected with ExchangeServices behavior?

Can I do anything now to prevent at least memory drainage? It renders my phone unusable as mobile device...

web browser exits after a few hours
I wanted to use an Android tablet for a browser-based info frame, displaying an autorefreshing page. I installed a program that disables screen timeout / blanking, I set the webpage as the homepage, I just need to click "browser" on startup and...

...and about 2 hours I'm back to desktop. Browser quits all by itself. The webpage code is fairly trivial, little chance for any memory leaks (simply reloading the target URL of an image inside a function launched with setInterval() ) and there is no manual intervention of any kind or any other activity performed by the tablet.

Is there any way either to keep the browser from quitting, or to have it restarted in case it does?

The tablet runs Android 2.3.3 (or thereabouts) and can't be upgraded to anything newer - it's a fairly obscure model with no rooting procedures available and the manufacturer doesn't provide any higher upgrades.

Semi-dead Tablet - Is this a touch screen trouble or just a software glich?
My tablet is HKC P077A with 8GB ROM, 512 RAM and a 7'' Touch screen (Android 4.0.3). I am having 2 problems

When I switch on the tab, first "HKC" logo comes to screen and then disappears to show "android". This is standard. But after that the thing wont move forward. Just keeps on showing "andriod" with a flashing like thing implying the loading process. But after long wait there is no start screen and nothing changes. It just hangs there....

But if somehow got it to get into normal working(I donno how, but It sometimes boots ok and gets into normal working mode, with home screen and apps and everything). So once I get it right the other problem I am having is that the touch is giving VERY bad response. I have to click at spots multiple times to select that thing. Also the response is very slow. Its like the tablet is hanged. But when I tried connecting a mouse (through OTG) and everything works fine again. Is my touchscreen gone bad..??

I am already done with, reset (from "settings> backup and reset") [I cant find how to do factory reset on this model from "off" state(read below)]

I have tried to get into reset screen by pushing "Power Button+Vol up" button. Then I know the tab gets turned on (I can hear a small white noise from the loudspeaker) but nothing comes to screen. So the "Robot with heart open" is never shown.
I also tried using "power button + Volume down", this takes me to a screen written in chinese.
Now, I don't know Chinese but from the look and feel, its a troubleshooting window, where I can check weather components of my tablet are working (eg. I click one menu(with difficulty), then the front cam turns on, another menu makes loud sounds from speaker and another flashes many colors in screen etc). I found that most are ok except something called "T" (On the screen, its the last item to the right, is it "touchscreen"??)

So, what can I do to get my tab to work smooth again..?
Is the touchpad having trouble..? Need I do any specific troubleshooting..??
Any Ideas on which key combinations to get on to the "factory reset" menu from off state..??

Now, I seems I have lost the ability to boot into Android. So I am now stuck on "problem 1(above)"

My phone handles RAM utterly wrong
Well I don't mind if there is only very few unused RAM. That's what RAM is for. But please, my Sony Xperia SP has 1GB RAM, which is I think should absolutely be enough for the tasks that my phone needs to handle, but it's intensely abused by factory Android and factory applications.

I only use a few apps on my phone: Gmail, Hangouts, Chrome, Spotify, Calendar and NewsBlur.

Some really annoying things that occur on regular daily usage, and can easily be reproduced:

I open a news page in Chrome, which has a couple high resolution photos - but nothing extremely much, maybe a few tens of megabytes uncompressed image data. (Or a few megabytes compressed). And boom! Chrome disappears instantly!

I'm typing a message on a web service, or fill basically any form on any website, that consist more that a few paragpraphs without images - either the browser or the keyboard application disappears randomly. On some websites, it impossible to type a full sentence. Does not matter if I use the factory keyboard, or SwiftKey.

It's essentially impossible to listen to music and browse the web at the same time. One of the applications gets killed after a short while.

Sometimes can't even text and listen to music at the same time.

Since my old Sony Ericsson cellphone could handle all of these without any problem ever, with one quarter of this memory, or so, I think either something is wrong with my phone, or it's firmware is totally unusable. I lean towards the second one, since my girlfriend's Sony phone has the same issues. And also, I don't think it's a hardware problem, since other applications run totally smoothly and with zero problem. NewsBlur and Calendar works perfectly, and I've tried installing some performance-hungry games, all of them run perfectly fine and smoothly.

I tried many things. Factory reset did not help, disabling 90% of all applications did not help, trying different keyboard software, music player, browser did not help much. I removed all the applications that I don't use on a daily basis, etc.

If I use a lightweight homescreen instead of the factory one, and switch to Dolphin browser or Opera Mini, things get a little better, but each problem happens on a daily basis anyway.

I have up-to-date firmware and applications.

What annoying is that Android seems to keep applications cached like homescreen, Play Store, etc. It's great that homescreen loads instantly, but I don't mind it killed, if that's required to keep keyboard in memory (while I'm typing, at least!)

What am I doing wrong? Is this normal? (It should not be...) Should I send a warranty claim?

I think it should work for so simple tasks out of the box, but I'm open to anything that helps. Unfortunately, on Google and Sony support forums I could not find anything aside clearing application data and using less applications. I already use less applications that I've used on my non-smartphone, and clearing application data did only rarefied the issues very little, and then everything went back to "normal", after a day or so.

So clearing application data does not really solve the problem. Also, I don't want useful information to be lost, so I think clearing application data regularly is not an option. For me, it seems that factory applications are so poorly designed, that they prefer loading huge amount of unimportant information to RAM, and killing really important applications to make space for it. And there is always still at least 150-200 megabytes of RAM left, when applications start to get killed...

offline navigation with public transportation
I can not drive (yet) and I get lost pretty easily.
So, I need a simple navigation app (I like the gmaps look, just roads, no fancy colors and things), which includes ALL bus/tram/metro/train (yeap, all of them) stations of greece, their schedule and navigation through them.
I NEED it to be offline, otherwise, I would use my favorite gmaps. Cellural data here cost A LOT (I have only 60MB/mo).
I've tested nearly each and every navigation app out there.
I don't care about the cost, but being free is a plus, especially open source.
I can extract the points of bus stations (I think) from the maps provided by greece.
I can also extract the schedules, but i don't know in which format.

thank you!
I've searched the whole web and I found no answer...

No Bluetooth option using Lenovo a269i
I'm an android first timer, who bought a Lenovo a269i. Lenovo's site states that it has bluetooth, http://shopap.lenovo.com/in/en/smartphones/a-series/a269i/ and plenty others in Internet do so too.

However I don't know, or can't find, where to turn it on or anything. It's not discoverable (if it exists) as I tried with to find it with my computer. I downloaded some "Bluetooth Shortcut" apps, and they all crash, I think... they try to open but return me to where I originally was. It's using android 2.3.6

What can I do? How do I fix the bluetooth? Or how do I know for sure it doesn't have?

Nexus 5 takes forever and a day to charge
Since I have installed franco Kernel on my device, charging takes longer than normal  (I'd guess 4-5 hours?). But today charging became extremely slow. I plugged it in overnight and this morning it was at 87%.

In the screenshot you can see that it was on for ~ 1d 20h, and ~ 1d 10h it was on battery. That means it needed ~ 10h to get from 4% to 87%. Is this a common problem with the franco Kernel?

How to track links that certain app accesses?
I always get concerned about backing up data that is relatively large, for the sake of bandwidth, which is kind of expensive in my area, really expensive.

For example, when I installed "Google Translate", I manually downloaded the language packs that I need, so I could install them whenever I want. I found the link browsing forums
http://dl.google.com/translate/offline/v3/r1/lang.zip

And now I've installed Google Text-To-Speech, and I wish to download High Quality voice data.
I haven't found any information about this on the internet.

So maybe you guys could help me, and tell me of possible ways to know, what url's or uri's are being accessed by a certain app while downloading cache or even just connecting for something?

Any advises appreciated

Factory reset generic android device
I have a cheap generic Android tablet (a Groupon special) that won't boot. <s>My theory is that the storage is full because this happened to two different tablets after installing apps.</s> update: I learned how to use adb to remove apps and this problem persists.

It gets to a Android logo screen in the boot process and hangs there. The only hardware buttons available are the Power and Volume buttons. I have already tried holding down the Power + Vol Up + Vol Dn buttons, and that does not reset the device.

I tried adb reboot recovery, but that only reboots the device and then continues to hang at the same screen.

I tried adb shell recovery --wipe_data. This causes the screen to flicker a moment, and then I get a Segmentation fault.

I'm stuck. I'm not a big Android guy so all this is from searching online and I don't quite understand what all is happening. Any other tips are GREATLY appreciated!!

Nexus 7: Can I set its WiFi to monitor/promiscous mode? If so, how?
Related question: https://security.stackexchange.com/questions/21057/nexus-7-or-any-other-good-android-tablets-for-pen-testing

I need to turn a Nexus 7 with Android in it into a wireless packet sniffer. I need to keep track not only of my own traffic but also of the traffic my WiFi interface can capture (hence the need to set it in monitor mode)

I've installed the Cyanogen mod to gain root's access so that's not a problem. It also has BusyBox to get some command line tools. Heck, I even compiled wireless-tools (following this thread)

I'm not even certain that even doable with the embedded wireless card in the Nexus 7 allows monitor mode? If it does, would it be possible setting it using regular commands (such as iwconfig, ifconfig) I'm old, and that's what I'm used to :-D (opening a terminal and typing things)

The about tablet says:

```<code>Kenel version: 3.4.0-cyanogenmod-gb7efce1
               build03@cyanogenmod #1
               Mon Feb 3 15:26:37 PST 2014
CPU:           ARMv7 Processor rev 0 (v7)
CyaongenMod version: 10.2.1.-flo
</code>```

I know it only has a WiFi interface (no 3G/4G) and also that it's a 2013 model Since my Wi-Fi's MAC address starts with AC:22:0B, I guess I have some kind of ASUSTek card, but I haven't been able to find the specific model.

Thank you in advance.

PS: If I can't monitor wireless traffic with a Nexus 7, I'm open to buy a new tablet with a network interface that accepts monitoring. I'm open to suggestions about what to get.

Notification Area Icons
Ad Block FAQ

How can I make the icon in the notification area go away?

We hear you, the icon is a bit annoying. But right now, it has to be there - otherwise > the Android system will just stop the app, and it won't be able to block ads anymore. > We have added an option to hide it - this is the best we can do.

This Question on Avast Forums says:

Android stops services that are not "necessary". The icon avoid it.

My question: With AdBlock, Avast and other "services" running, the bar remains "full". Even if you "hide" the icons (like is available in AdBlock), it results in blank spaces that sully the look (First world problem I know). You can Disable the icon with Avast but it warns you of the obviously impending doom that can possibly maybe descend on you (The icon helps Avast! protect your device better. Are you **SURE** you want to turn it off?)

I'd like to be able to disable these without the fear of Android killing said service. With 4.3 and 4.4, are there any new options to remove those icons without fear?

Android Droid 1 only partially recognizes SD
My Motorola Droid began experiencing a weird quirk where when booted it recognizes the SD card, but only once. After that some applications complain that there is no SD card inserted and persist until rebooting again.

For example, I can take a picture, but any attempt to take another picture results in a warning that an SD card must be inserted.

Oddly, music and apps which were installed on the SD card work fine, and I can browse it with a file browser. What causes some apps to not recognize it and others to work just fine?

It's probably worth noting that I'm using a Liquid Smooth ROM with Launcher Pro; though I hadn't had any problems of that type until today.

Root Samsung Galaxy Tab 3
I'm continuing my quest on turning an Android device into a WiFi sniffer (see Nexus 7: Can I set its WiFi to monitor/promiscous mode? If so, how? ) I found an unused Galaxy Tab 3 (model SM-T210R) so I'd like to try that one.

First step, rooting it, right? Well... it turns out to be a was more difficult task than I imagined... Cyanogenmod doesn't have a version for Galaxy Tab 3.

With a bit of apprehension I tried installing this one: http://techbeasts.com/2014/01/19/how-to-root-samsung-galaxy-tab-3-7-0-sm-t210t210r/
but when the Galaxy tries to install the from the .zip, I get:

E:failed to verify whole-file signature
E:failed to verify whole-file signature
E:signature verification failed
Installation aborted.

which, according to the comments of that teachbeasts.com page, seems to be a pretty common issue.

Has anyone successfully rooted a Galaxy Tab 3? If so, could you point me to the web or resource where you found the method?

Making SMS sound and other notifications play in speaker with headphones inserted
I would like to be able to go to sleep with headphones plugged into my S4 so that I can listen to podcasts, but then there is the problem that I don't hear SMS messages or calls during the night, because the notification sounds are played in the headset also.

What I need is that every incoming SMS message and phonecall notification are played through the speaker and not the headphones. It is not a problem if this causes the podcast or music in the headphones to stop while the notification is playing in the speaker.

So is there an app or other method that fixes this?

I have checked Soundabout, but it seems that it is not able to force notifications to speakers, only phonecalls.

Edit:
There is a related question, but that one is limited to phonecalls, and it seems that there is a difference to routing the sound for phonecalls, to other notifications.

Media audio plays through front speaker?
I've got a Nexus 5 running stock 4.4.2, not rooted. Sometimes, seemingly at random, I will go to do something that plays sound (watch a YouTube video, play a podcast, etc) and the audio comes through the front speaker (the earpiece, where you'd normally hold it up to your head) instead of the bottom speaker.

When this happens, the volume buttons always change the "phone" volume (handset icon) instead of the media volume (speaker icon). Stranger still, some applications still use the right output - Amazon MP3 will play through the normal speaker, but Pocket Casts won't, and because of the volume button issue there's no easy way to change the actual loudness of the former.

I'm having trouble finding this issue on forums. Does anybody else get this? Is it special to the N5? Is it caused by a specific app? Can I stop it from happening, or at least recover from it without rebooting?

Installing Google text-to-speech hd voices on sd card
I use the Google text-to-speech engine and it has the option to download high quality voices. Those are about 250 mB per file, and i barely have any internal memory left after i download them. Is there a way to move those to the SD card?

I have link2sd installed, but I would need to convert the engine from system app to user app to link the app files, and I suspect that this would cause all kinds of unforeseeable problems. I think that i would then also have to do the procedure of converting this app to system app and back for every rom update i flash, for the cyanogenmod update script to work -or maybe that step wouldn't be needed since userapps do not get touched anyway?

Well, even if the above would work, i would prefer a simpler solution.

Has anyone successfully moved those files to the SD card?

UPDATE IN CASE ANYONE READS THIS:

Apparently i would be able to move those files with the new paid version of link2sd, but i have by now decided not to use google's hd voices. There are better-sounding alternatives available for free on the market, and google voice search / google now use their own voice (i think it's network-synthesized) anyway.

Confirm my MicroSD is not faulty.

Format MicroSD to FAT32, then image Verizon Stock firmware through Win32 Imager.

Enter into "Download" mode on the phone.

Confirm my Windows 7 system recognizes the phone. To do so, I confirmed the phone enters into "USB Debugging mode". Window7 recognizes the phone as "MSM8960".

What is filling my phone's RAM, if not apps?
My Galaxy S3 has gone from snappy to slow over the past few weeks: When I open or change apps it reacts very slowly. When the app is running that app is working fine.

It resembles having too little RAM in your computer: When the program you are using is swapped in, it works just fine, but when you open a new program or switch to a program that is swapped out, it is dead slow.

So I looked into the memory usage of my phone to see if that might be the case:

It seems my phone is using 750 MB RAM for something it will not tell me.

Others online have suggested the memory is just used for disk cache, but then it would never slow down the phone.

I have rebooted the phone and then the unaccounted usage goes to 500 MB RAM (Is that really the normal RAM usage for a freshly booted phone?), and the phone is much more snappy. That makes me think it is a memory leak.

How can I see what accounts for the memory usage not shown in the "Running Apps" page? How can I release it? If it is a memory leak: Can I add swap so that the leak at least is swapped out?

Android version: 4.3. Baseband version: i9300xxugmk6.

Allwinner A13 tablet stuck on boot screen
Okay, here's the deal- I received a generic Chinese tablet from a friend in early January, and it worked well for about two-and-a-half months. Then, just recently, I discovered rooting and the wonderful things it allowed you to do, and my problem followed shortly after. I decided to download a system-tweak app, which included a CPU control. I was a little wary of overclocking my CPU, having heard it may decrease its life expectancy, but finally I thought "What the heck?" and in a brilliant stroke of genius cranked my 1Ghz processor up to 1.5Ghz, and it promptly froze, forcing me to power it down. When I turned it back on, I discovered that it had been factory reset. I re-installed my apps, including the system-tweak app, and decided not to touch the CPU controls for a while. Soon after, while at my sister's talent show, I discovered I had about 30% battery life, and I was still supposed to record her. So I figured I'd underclock it to save the battery. Unfortunately, as my finger touched the slider, my brother bumped my arm and caused me to lower the CPU frequency to its lowest setting. It became extremely sluggish, almost to the point of being unresponsive, and finally I had to shut it down. When I restarted it, it started to boot but then got stuck on the shimmering Android logo, and now that's all it does. I can't even boot into recovery mode, and unfortunately I had just turned off USB debugging that same day. I would like to know if there's any way to get it working again, and if so, how. Any help would be GREATLY appreciated! </p>

Enable usb debugging mode from adb under clockworkmode "Broken digitizer"
My friend brought me a Xtreamer Q mobile phone with broken screen, clockworkmode is working, but USB debugging mode is disabled, I found some posts about how to enable it from adb i tried them and none of them worked.
here :

https://stackoverflow.com/questions/13326806/enable-usb-debugging-through-clockworkmod-with-adb
and from this tutorial i learnt how to edit build.prop file.

http://www.modaco.com/topic/328943-quick-guide-to-modifying-buildprop-with-adb/
the commands i have used are: adb pull, adb remount, adb push.
While i was under clockworkmode i mounted system and i pulled build.prop then i added this line to it persist.service.adb.enable=1, used remount then pushed the file after that reboot, but i couldn't find the device in adb when it have booted normaly.
Next i tried to set adb_enabled to 1 in /data/data/com.android.providers.settings/databases/settings.db by following some steps from here

ttp://forum.xda-developers.com/showthread.php?t=774507
and it also didn't worked "The device was not listed".
Also i have tried this zip file from clockworkmode it didn't work too...

Install adb enabled setting from zip

My phone do not support USB org cable

Google + cloud autobackup confusion
I installed the Google+ application, I then enabled "Auto Backup" , and checked "Back up local folders"
it says "uploading 173 of 600" and some of the photos in the gallery have a "cloud" icon on them (I assume this means they are uploaded to my account).

When I go to my Google+ account I can't see any photo there. I even tried searching for #AutoBackup and there are no photos. This is an hour or so after I was connected to Wi-Fi, of course.

What am I doing wrong?

问:
Tablet stuck in boot animation
I have this tablet, MSI Primo 91 and just recently I booted into recovery mode in order to wipe the cache. On restart the tablet gets stuck in the manufacturer boot animation and refuses to boot up.

I then tried to reboot into recovery mode when the android laying on its back pops up. The recovery options won't show up.

This guy here.

The device restarted and gets stuck yet again in boot animation.

I visited the website to download the firmware. I followed the ritual described in the pdf instruction file and I couldn't  recover the tablet.

Right now, I just as stuck as the tablet. How can I fix this?

LG G2 music player hooking into bluetooth?
I have a 2012 C250 that I used to hook up to my RAZR MAXX, and was able to control the music (Google Play Music) from the car.

I now have an LG G2, and I noticed in the beginning that the LG player would fire up when I hit my car's commands. If i manually start Play Music, the car will intermittently recognize it, but mostly the control functions are useless. The car will still receive the audio and phone fine however.

I have rooted my phone and frozen the LG player, but no luck. All of my music is on Google Play, so unless there is an app which can play GooglePlay music that plays nicely with my car, I'm kinda stuck.

Anybody have any ideas? Thanks


问:
Nexus 5: Different home screen with lockscreen enabled vs disabled? Huh?
community:

I am a new Android user, and I've spent most of the weekend banging around on my Nexus 5 making it work the way I want. For the most part, I am super happy. But, I'm experiencing something weird that I can't find any documentation for, and I can't tell if it's expected behavior that I think is weird to me because I'm new to Android/Nexus 5, or if it's genuinely weird.

After I got the phone, I disabled the lockscreen. I didn't intend this to be permanent--I just did it so I could get to the home screen faster while I was installing new apps and setting up the home screen. (I think I'm using the right terminology -- "home screen" is the screen displayed after you turn on the phone, and displayed again any time you press the home button, right? Because, home button?)

After I got the home screens looking the way I want, I re-enabled the lock screen with a swipe to open. With the lock screen enabled, after I swipe and then dismiss the Google search screen, I don't get my nicely configured home screen that I spent several hours on -- I see the original home screen that came with the phone, with most of my apps not available. When I click Home, I get my "good" home screen, and I can't get the old weird one to show up again until I turn off the screen. Then, when I turn on the screen and swipe and dismiss the Google search, I'm back to weird unupdated home page.

When I turn the lock screen off entirely, the correct home screen is immediately displayed when I press the power button.

I was willing to shrug my shoulders and say "Android is weird, I'll just set up this weird post-swipe homescreen to look exactly the way I want, and then it won't matter," BUT not all of my apps are in the app list to add to this weird unconfigured home screen that shows up after I swipe away the lock screen.

So, to get to the home screen I want, I have to swipe the lock screen, dismiss the Google voice/search prompt, and then press the Home button, which shows the good home screen, and there's no access to the bad home screen until I press the power button off, then on, then swipe again.

Attached please find screen shots of:
* The first thing I see if the lock screen is disabled---this is the desired home screen
* The first screen I see if the lock screen is enabled (after I swipe away lock screen and dismiss Google prompt)

Can anyone shed some light on this for me? I really appreciate the help and I thank you in advance for assisting a newbie.

Regards,
Elissa M.


问:
Android emulator with snapshot option not working
I create an android device with configuration:

API Level 19 (4.4.2)

CPU : ARM(armeabi-v7a)

Emulator option :Snapshot Enable .

For the first time the device load takes approx 3 mins. After that loading the device with snapshot takes 20 sec. But I found that I cannot access the device through adb or through GUI. I think this is a bug. Any way to resolve this?
I tried loading android device earlier also with snapshot but in windows system presently my emulator is setup on a mac machine.
