Hidden Root Browser on MIUI?
I have just installed MIUI on my phone and when I was about to select a picture to attach to a message, I was prompted with the following:

The thing is, I don't have Root Browser installed. I also can't see it on the list of apps on the MIUI launcher. But it's being offered as an option when I choose files and it works. Can anyone explain how this is the case?

2G vs 3G Talktime
When I was going through  specs for my Xperia SP, I found the 3G talk time to be more than the 2G talk time.

```<code>Talk time:  Up to 10 h 25 min (2G) / Up to 19 h (3G)
</code>```

More over I went through the specs of a few more new mobiles and in all specs 3G talk time was more than 2G talktime.

As per the specs of my old mobile the 2G talktime is more than 3G talktime.

How is it that the new mobile are able to save battery by using 3G?

And when data is turned off will there be any difference?

Why can't the Sprint HTC One use GSM ROMs?
Everywhere I've looked, I've found that the HTC One physical hardware (USA) is the same regardless of the carrier--all models of the USA phone containing both CDMA and GSM radios.

If this is the case, why can't the Sprint variant of the HTC One be hacked to work properly (see issues with Sprint-variant SIM unlocking here) with USA GSM networks like AT&T? Or use GSM  ROMs for that matter if all the USA hardware has both radios.

I ask because I made the mistake of buying a Sprint HTC One on eBay with the intent of unlocking to use with my existing AT&T account. NOTE: I am not talking about 4G/LTE data, only 2G and 3G.

How do I delete a calendar/swipe lock-screen that appeared after Android 4.3 update?
Recently, an Android 4.3 update appears to have created a strange and unwanted calendar/swipe lock-screen on my Galaxy S III which is pictured here.

The calendar provides an inaccurate date with a visible calendar event, and the X... ...zZ has to be swiped before I can get to my regular unlock pattern.  I am unable to get rid of this screen which pops up irregularly and is really annoying. Any ideas? Thanks.

Tasker (switch off mobile data automatically) causing trouble under CyanogenMod
I used to use this Tasker profile for nearly a year now already and it used to work fine, until I recently switched from the Samsung default UI TouchWiz to CyanogenMod on my Galaxy Note.

What the profile should do is switching the mobile data connection if it's turned on-off 11 seconds after the display turned black. Seems not too tricky.

But running CyanogenMod, it doesn't work anymore; what now happens is: after I booted my smartphone, everything works like a charm (connection via mobile data is stable and accessible immediately after you turn it on). But after the first time you switch off the screen (that's when Tasker kicks in), nothing works anymore. The mobile data is switched off, yes - or at least, there's no connection anymore. But the system itself seems not to realize this properly as both, in the settings as well as in the notification bar, it's still displayed as "on". You can switch it off there too, but either way, there's no way to turn it back on (yes the switches still work, but they don't have any effect).

Description:

```<code>Profil: mobile data [off] (16)

Possible Virus; Eratic Behavior on Galaxy Pocket Neo
Some time ago(a few months) I've bought a Galaxy Pocket Neo from a local internet store, which isn't really famous (actually everyone I asked knew nothing about it). It turned out to be a branch of mobileshop.eu, which was also unheard of by me or anyone I know. I'm saying this because I cannot be sure whether the OS itself was bought infected or with a backdoor or something like that.

After several weeks of using, I've noticed rapid battery drain overnight, from 70% to emptying(the phone was turned off when I woke up). Not sure whether it's important, but sometimes, when I turned it on again, I got report that battery is on 252% or similar numbers - I assumed wrong calibration. The weird part is, when my phone 'survived' the night (happened a few times), and I tried to use it in the morning, it felt like I was fighting with someone to control the phone, like someone was tapping on my screen - except no one was near me. I solved that problem once by turning it off (took me a couple of minutes, the other one was fast), and when I figured out I could just remove the battery I used that 'technique' (duh, mornings). Then I'd just turn it back on and it'd be normal, for the rest of the day. After a few days I've started turning off wi-fi&sync (mobile data was always off), and my battery only have lost a couple of percent. When I turn them back on in the morning, it's normal.

The thing that persisted is the silencing of the phone and/or putting it on vibration. I'm sure that didn't press the button accidentally or something, that can happen even when the phone is just sitting on the desk. From what I've noticed, the screen doesn't turn on, but I hear the vibration. Cannot tell whether that happens overnight, since my phone is usually on vibration/silenced during that period of the day. I've checked the app permissions, didn't notice anything weird (if you could instruct me for what to look, I'd be grateful). Only non-play app I've installed is the Youtube Downloader from github.

So, does anyone have any idea what I'm dealing with? I'm quite new smartphone and Android user, but I know my way around desktop PCs/Linux/Java/some C and experimenting with them, so any help is welcome. If it is a virus, what is the best way to remove it? From what I've read, the Android antiviruses aren't really effective (and if there are any that could help me, please list them), and custom ROMs should erase everything (I'm ready to take that step if needed), but are there any more options? Rooting the phone and uninstalling everything? If it's a bug or something I'm missing in settings, please notice me, preferably with instructions how to fix it.

Thanks.

How can I revoke an app's permission to access USB after granting it permanently?
I have an app that requested USB access, and when prompted I selected "Yes, allow this app to use USB" and checked the "permanently" checkbox.

Now I would like to revoke this permission so that the app would always have to ask every time it wants to use USB.

Is to possible to do that by changing something in system settings? Where? Is there a permission manager built-in to the system? If not, then is it available as an external app?

问:
Android / S3 (i9300/i9305) - Disable default keyboard pop-up at lock screen
After the 4.3 update, there is a default keyboard popping up at lock screen.

Let me describe what I mean.

When you opened up your phone pre-4.3, it displayed the lock screen. With no keyboard or anything, just the information. Like the clock, your missed calls and such. When you tapped into the password field, the keyboard popped up. It was all buttery smooth, looked good, worked good.

Here comes 4.3, ala Samsung. Now if you lock your phone, it will pop up the keyboard every time.

This saves one tap, that's a pro.

But:

It tears apart your wallpaper, as the keyboard - which won't get loaded in time - got your wallpaper, not the lock screen wallpaper.

As I said, the keyboard just can't load in time. This is not a bug, it's just not possible to wake it up from deep sleep and throw so much work at it.

So overall it looks glitchy, cheap, awful. Like some copycat Chinese fake smartphone. Which I believe the S3 is not. It's just untasteful. Ugly.

I understand that this was most likely a design decision, to speed up the unlock.

Is there a way to disable this behavior?

Rooting is OK. I mean, this thing looks so ugly, I'm fine with losing my warranty.

Just let me fix it somehow.

Custom keyboards: I'm using AI Type keyboard (free) as for now, but the glitch and the auto-pop up happens with any keyboard I tried. It's like there is an event defined, so it's like you would "tap" into the field.

Custom lock screens: I looked around as much as I could, but I only found "press to lock" apps. Basically little widgets and buttons to lock your phone. But they were no custom lock screens, just shortcuts.

Wake-up apps: Tried "Auto Wakeup", but it only wakes the phone up the very same way. With the keyboard, lag and all. :/

Android USB Debugging on Mac OS X 10.9.1

Softbrick after Phone hanging. Rooted but Stock ROM on Nexus 5
I have a really big problem... I have my Nexus 5 for 2 months now and not it doesn't restart anymore.

My phone is rooted and on Stock Android 4.4.2 and enabled developer mode (tapping that 15 times on the build number in settings menu) but I haven't changed that much. And it worked for over a month now. Since the last change in software or settings, the phone was rebooted at least twice.

The last thing I have done was using the app OpenSignal to check my Signal coverage while playing some music over Bluetooth. Because I had enabled that visual feedback for touch, i saw, that my touch on some diagram in OpenSignal was recognized. The Music stopped immideately and the device freezed. Then I tried to reboot it by holding the power key long. The screen went blank.

Then I tried to restart it by holding down the power key long. "Google" appears on screen; screen went blank. Nothing. This is repeatable.

Connecting to a computer shows the "Charging" screen. This is repeatable.

The tried to put the phone into recovery mode. By holding down Vol Down and Power for a quite long time i got that in that mode. than double Vol Down and Power. The screen showed a strange glitch. Like a gameboy that runs out of battery, the lines shifted inside each other. Screen went blank again.

I still can reboot to the Google screen and get the charging screen. I hope it is only a Softbrick and not a Hardbrick. How can I get it working again?

I just have recognized that sometimes after the Google-Logo the system goes to these balls but freeze before the first ball (Red one from left) could be seen completely.

Screen size off after porting ROM to my phone. How can I fix X and Y values of the screen?
I am trying to port JB 4.1.2 to my phone using a kernel from another phone of the same spec as mine. I have 98% of things working but the screen is probably the most troublesome.

CPU MT6577
Android version 4.0.4 ICS
Phones Display is an LG 720x1280 but not sure exactly which one.

The Screen driver is contained in the kernel and I wondered if there is anyway to make adjustments to center the screen either during the boot process with added commands in the init.rc or via adb and even after boot as completed with any kind of apk.

I have tried adjusting the screen with am and wm commands via adb which work but it is all contained within the frame. If that makes sense.
What I think I need to do is adjust the x & y values to shift the entire frame. Please see the image and all will be clear lol.

Please bear in mind my level is Noob so if this requires kernel decompile and rebuild then its a none starter and there are no sources for my phone anyhow :(

Better way to deal with "Only part of the message has been downloaded" mail warning?
I'm using the stock e-mail app on Android 4.3.  This morning, when I tried to forward an e-mail to another person, I got a warning that popped up which read:

```<code>Only part of the message has been downloaded.
If you continue, the rest of the original message may be lost.
</code>```

I get the same warning if I try to reply to the message.  I tried pressing the "sync" icon above the message.  I tried waiting a while for the message to finish downloading.  I still got the warning.

I finally resolved the issue by scrolling all the way to the bottom of the message, but this is a rather bothersome solution, requiring time and lots of finger flicks. I don't see anything else that seems relevant to the problem at hand, but surely there must be some way better to resolve the problem?


问:
Why did the app name "Android OS" suddenly spike in data usage?
I have a couple of questions here.  I am using the 2nd generation Nexus 7 tablet (wifi only) that was connected to my personal mobile hot spot.
Yesterday, I saw a spike in my data usage that was lumped under a process called "Android OS" that I had not seen before, in the few months that I have owned this device and started tracking its data usage.

In the course of 1 hour, it devoured about a gigabyte of (background) data according to the "data usage" under the settings.

I also have the Onavo app.  In that same time, it reports the data usage under the process "Streaming Media".

I presume "Streaming Media" and "Android OS" are the same underlying process.   Am I correct?  If so, why are they reported differently in these apps?

I have just discovered "Mobile Hot Spot" spot setting so I'm hoping that will help.  As I had not seen this process usage this much database before, I had not thought to look into tweaking this setting until I started Googling around.

Can someone fill me in a little more here, or why I might have seen this sudden spike in data usage which I hadn't seen before?  The only big streaming app I used yesterday was Spotify.

I made the mistake of buying a cheap Chinese phone on Ebay to use on Three or Orange in the UK, a 4" Malata I60 Android 4.1 Dual Core MT6577 1GHz. It's okay for what little I need, except the internal storage shows as a total of 179MB.

I've moved whatever apps I can to my 30GB SD card and using App Cache Cleaner, but I am still only left with 36.8MB of free space.

This is causing warnings whenever updates are found and even causing updates to fail for lack of space if I am actively using the phone.

Does anyone know where I could find reliable step-by-step guides to rooting Android 4.1 and using the SD card for internal storage?

youtube app - is there a way to resume play back
I have an android set top box call Pivos Xios. It is running android 4.0.4. This is plugin my 1080p TV. This device is great because for 100$ you get to have a browser on your TV and all the play store app you already purchased are available.

So I have installed the youtube app which works great. I logged in my account and get to have my history and my watch later videos, that is just awesome. I was just wondering if there was a way to resume playback of a video that I stop/paused for a later view.

I know I can do that with the XBMC app and the youtube plugin installed, but the interface is much less intuitive an user friendly that I prefer to use the youtube app directly.

On my PC, sometimes (I haven't found what triggers it), when I reload a page of a youtube video I've already been watching, it is sometimes cropped from where I stopped it. There is a bracket added to the timeline.

I'm looking to have a similar functionnality over my youtube app on android.

Any advices are welcomed.

Sometimes the screen is on when in lock mode
I have a Samsung Pocket GT-S5310L and sometimes, when the lock mode is on the screen never turns off (until I turn it off manually). This started to happen after I made a factory reset

When charging is ok but when I leave the phone and I receive a notification the screen stays ON. Stopping notifications is not an option and I couldn't figure out what the problem is.

Any idea what could be happening? If I can't find a way to solve the problem, I think I will do another factory reset (which I didn't want to do but I am running out of ideas).

Port not open when using portable wifi hotspot
I just bought a Samsung S4 and am using its portable wifi hotspot feature for internet connectivity on my laptop when I go out the house.
Works just fine when browsing the web(actually quite fast) but when I use uTorrent, it has an orange exclamation point icon near the bottom right. Downloads are slow even if I have 20-30+ seeders(around 6-10kbps max). Did a quick google search and found out(using canyouseeme.org and port forwarder port checker tool) that the port used by uTorrent is not open.

Checked my windows firewall exception and there's already an exception for uTorrent. I've even added new inbound and outbound rule to specify the port used by uTorrent but no luck.

I believe I've covered everything on my laptop (win 7 64bit).
BTW, when using the same laptop but using my parent's dsl connection, DL speeds jump to a couple of mbps of the same torrent(facepalm).

Sorry if post is long. I just wanted to explain it thoroughly and to show the things I did to try and resolve the problem. I'm just new to android. Be gentle (but not too much.... harhar!)

Is there anything I need to do on my S4? Hopefully without rooting it. Or to my laptop?
Thanks a bunch guys. :D

PHone rebooting when screen turns off
My phone started rebooting all by itself all the time after I did 2 things with it. Installed Snapdragon BatteryGuru and put it on learning mode (for an estimated 3 days I guess) so that I could start saving battery by the app learning my behavior, and cleaned RAM with CleanMaster. These were the only changes I've done, I don't remember which was first but soon my phone started rebooting whether I was handling it or not at random intervals. I've also noticed the phone was hot all the time, the Note 3 runs into some hot period with some frequency but not with that frequency.
I've uninstalled both apps and it didn't work, wiped cache and it didn't work. The phone was still rebooting even on safe mode. After I wiped Dalvik with the help of TWRP, I thought the problem went away but when I hit the power button to turn the screen off, the phone rebooted and it will now always reboot when the screen turns off, even if it's just from the phone being inactive.

YouTube Acting Up?
My phone is a Samsung Galaxy S Blaze 4G running Android Gingerbread 2.3.6. My YouTube application is version 5.3.32. Lately (for a while actually), YouTube acts strange. Nowadays, a normal startup results in the app taking several seconds to start and locking up my home screen in doing so. A "messed-up" startup results in the app freezing and not even opening, and my home screen locking up. When this happens, I usually have to press (more like spam) the Home key until the phone finally responds and the app closes. Sometimes, when a "messed-up" startup occurs, I can go into my application settings, force-stop YouTube, and it works fine. Other times, I have to play around with app startups and force stopping before, eventually, it'll let me in. Then, the problems aren't limited to startup - On random occasions, the application will freeze up and crash, whether I'm refocusing on it from something else or randomly during the video. Can anyone please provide help or feedback on these issues?

APN doesn't save in Tablet AOC Breeze
I have a tablet AOC Breeze model MW0712 with Android 4.1.1.

When I want to save an APN I do: Settings -> Mobile networks -> Access Point Names -> New APN

But after editing the APN settings, there are no button to save the changes.

The only proven way I have to save an APN is typing in the fields:

Name

APN

Username

Password

and leaving blank the MCC, MNC, Authentification Type and APN Type fields. With this way the APN is saved but doesn't work. If I edit the APN I've saved and I put the values for these fields, the APN disappears.

With Root Explorer I open the apns-conf.xml file (readonly) and I see full of different APNs, but APN selection screen (Settings -> Mobile networks -> Access Point Names) is empty.

问:
Wallpaper doesn't rotate or stretch to match the screen when in landscape mode
I have a Samsung Stratosphere, running Android 2.3.6. My problem is that when I'm on the home screen and I slide the keyboard out (putting the device into landscape mode), the wallpaper does not change with the rest of screen. For the purposes of illustration, I've made a home screen less cluttered than my real one, and used a wallpaper whose orientation can be more easily discerned (see here for the full image). Click on the screenshots below for larger versions.

As you can see, the wallpaper doesn't rotate to match the orientation of the screen, nor does it stretch; there are just some (very silly looking) black bars.

I owned a Stratosphere for a few years, during which I never had this problem with the wallpaper; however, the wallpaper I used during this time was just an image consisting of just a solid color, so I can't say for sure whether the wallpaper was being rotated or stretched. All I know is that I never had any black bars. But I recently dropped it and had to get a replacement via my Asurion insurance policy, and now an ostensibly identical device has this problem. Any help would be appreciated.

S4 in safe mode, Odin on restart
Last night my phone was running slow so I restarted it, when it went to turn back on however it came to a screen with a warning about loading a custom OS and I had the option to either continue by pressing volume up and to decline by doing to opposite. It took several times of me doing this to turn it back on. At that point when I turned it on it was not in safe mode so I went to restart it again to see if I would run into the same issue and I did repeating the same steps as before. Finally it cam back on but in safe mode so I turned it off again after doing a factory reset hoping that would work. Now I am in safe mode and unable to use any downloaded apps or pictures and I cannot delete any files.

I was looking into rooting my phone a while ago but as I have no compute at the moment I decided to not do it after all and because it looked too complicated. I had not turned my device off since then until last night. I don't believe I downloaded anything but I'm not sure because it was more than a month ago. If there is a way I can fix this without bringing it to Verizon or even if I can root it and then unroot it to bring it back to normal. Or just keep it rooted if uprooting it is too risky.

I got my Nexus 5 two days ago.

So far everything was fine until one moment and without any apps I installed (until the day before) device hangs on connecting Orange (in NC).

What actually the problem:

The phone is not connecting in any way to Google Service, not through cellular and wifi   (Please note the connection of the wifi is used to a multitude of devices that serve me  and is completely works every time without any problems).

Things I've tried so far:

1. enter/exit flight mode.

2. turn off/turn on the device.

3. turn off/turn on the device in safe mode.

4. Stop the processes: "google play service", "google play store" and delete all of their cache memory.

5. Change the position of the clock time (I read somewhere that it might help).

6. Delete updates from google play (back to what came with the stock).

7. Delete the APN and restore it from 0.

Please note the device has rooted, If needed I will list exactly which applications got installed with root privilege.

CPU getting hot. GPS can't lock on
I know this was probably asked several times, but here's the deal: A couple of months ago I was charging the phone (Alcatel Onetouch Star) at my friends house, when I got a warning that the phone was getting too hot. After that, every time I use anything that's at least a little resource hungry (Facebook, note apps, video player, browsers, and obviously Youtube and games) the area below the battery gets warm, and almost burns my hand in some cases.

The battery itself doesn't get warm. The area below it, where the capacitive buttons are does. I'm guessing that's where the CPU is, and its getting hot. It didn't get hot before that night, it'd get only slightly warm when using YT or larger games (even in summer), but lately it's getting too hot, even though its winter and ambient temp is much lower than it was in summer.

Any ideas whats causing this? Oh, and also the phone can't get a GPS lock anymore. Not even after 5-10 mins under 7-12 satellites. I'm holding off on rooting it until I get everything sorted out, as I still have the warranty.

How can I edit a video to correct an incorrect orientation?
I recorded a video clip on my Samsung Galaxy S4 in the horizontal orientation. If I download it to a computer it plays correctly in a wide aspect ratio and is not rotated.

When I play it on the phone, the phone always rotates it incorrectly.  If I hold the phone in the vertical orientation, the video fills the screen, but is rotated 90 degrees. The bottom of the frame is on the left.

If I rotate the phone 90 degrees CCW to view the video in the correct orientation, the phone rotates the video another 90 degrees.  Now the video is a tiny thumbnail in the middle of the screen - a vertical video showing on a horizontal screen. The bottom of the video is still on the left.

Why is the phone rotating the video incorrectly? Isn't the phone supposed to note the orientation and tag the file when the video is recorded so this problem won't happen? Given that it has it wrong, how do I edit the video to correct the orientation setting?

In Outlook on Windows, I can read this email just fine.

However, clicking the 'Decode message' button which my the standard Android email client shows me (on Android 4.1.2, through the Exchange connection) results in a message 'Cannot show encoded messages.  Certificate not installed.'  (Label and message actually show up in Dutch on my phone, I've guess-translated them back to English.)

My question: How can I make the Android email client trust this CA certificate, so that it allows me to read these mails?

Update: I'm not asking for how to add a certificate with a private key (as can be used for authenticating to a wi-fi network), but a certificate with just a public key (which can be use to verify signatures).

how to get control-/ or control-_ to work
I'm using the Hacker's Keyboard, which provides extra keys such as control, alt, and so forth which are necessary when doing things like shell commands.

I'm having an issue where I can't undo in emacs using a single keystroke.  Using ctrl-x,u works, but it very clumsy on a tablet, due to the fact that the there is no tactile feedback  - so to undo accurately I have to type very slowly, which is the opposite of what I want to do when undoing, which is to quickly jump back several states.  I could add something to my .emacs file to choose a different keystroke, but now I have several machines that I have to create or update an .emacs file on, so I would like to use the default if possible.  And there is also the question of what key I would use: for instance, control-z is one possibility but that is already taken by suspend process.  control-u is another, but it is already taken too.

The two default single keystrokes that emacs uses to undo are control-/ and control-_.  However, when I try both of these keystrokes in Android, the control part seems to get lost.  I have also tried cat | hexdump or cat directly from a shell prompt (ssh or terminal) and the control seems to get lost in those two, instead of seeing something like ^_ as expected.  Other control characters work just fine, so I can't see how it's a general issue with either app not recognizing control characters.

From reading various pieces of documentation it seems like Android 3.0 Honeycomb added support for all the various control characters, although looking directly at the Android documentation I don't see a code for everything, so I'm not sure if this is something that just isn't supported or if the application is at fault, or if there is just something else that I have missed that is needed for this to work.

Browsers are using default application, not themselves, to open links -- how do I fix this?
Yesterday on my phone (Android 4.3.2, Galaxy 4S) Chrome started opening the stock browser (just called "Internet") when I clicked on links.  That's not what I want -- a browser should use itself to open links unless I tell it otherwise -- so I cleared the default settings first for the other browser and then, when I saw the reverse happen, also for Chrome.  So currently I have no default browser and each one asks me what application to use -- every single time.

Before this problem arose, links originating from outside of browsers (like email) opened in the default browser but links from within any browser opened in the originating browser just like you'd expect, with no "what do you want to open with?" dialogue required.  What do I need to do to get back to that state?

I intentionally use two different browsers to keep different web-site credentials from bumping into each other.  I don't want to always use exactly one.

How to set a better encryption password
How would I go about setting a stronger password for disk encryption on my android device?

I had set a PIN already before enabling full disk encryption, and it proceeded to use that PIN as the decryption string when the device boots.

I understand that switching my PIN / Password will update the decryption string as well, but entering a password every time I unlock the phone is a serious inconvenience. Similarly using a short integer to encrypt the disk leaves it much easier to decrypt.

How do I go about setting a better decryption password, while keeping my PIN? I have no interest in solutions that require rooting the device.

Choose Which Albums Show in Play Music?
Not sure if this is a common or simple solution, but I can't find a way to fix this.

I've got a couple albums I've purchased through the Google Music store - namely the Lés Mis soundtrack, is it's a great musical and all that.

However, it's showing up on my phone, and I don't particularly want it on my phone.

If I shuffle my music, it keeps turning up.

If I make an instant playlist, it likes to show up. (Because apparently Lés Mis is very similar to Rust in Peace...)

I could set it to only steam via Wi-Fi, but then I need to keep the rest of my music on the device. And besides, as soon as I get on the Wi-Fi, it'll start streaming again..

How do I stop this album from showing up? I'd rather not delete it from Google Music Manager as that'll delete it from my account (I think). I just don't want it to ever show up on my phone.

Replacing the flash chip on a Galaxy Nexus
A little background

I have two Galaxy Nexus phones: one reported lost(was lost) 32GB and a current 16GB version.

Current Issue

I'm trying to put the 32GB flash chip into the current phone. Which means moving the SIM tray/flash card from the old phone to the new one. Shouldn't be too hard, just replace the circuit board and use the correct SIM card.

When I turn the phone on however, it says there is 0-1 bars of unusable signal(no data). I use the old tray and it works perfectly. Is there some chip in this board I don't know about?

问:
How to prevent widget resize on unlock swipe?
After upgrading to 4.3, there is only a small portion of the lower screen that can be used to unlock the phone.  The upper part of the screen engages what looks like some sort of draw or resize box with a pencil in the lower right corner.  I think it is trying to resize the clock widget for some reason.

This is very annoying since I never want to resize the widgets after they are set, but obviously, I swipe the phone a lot.  Is there a way to disable this box and return the swipe area to the visible window?

How can I store my Google maps (and maybe directions) offline when previewing directions?
I want to ask directions when I have a Wifi connections, then preview the route and store the maps offline for the entire route - so that when I'm underway I can just let GPS pick up my location and show me a map (and preferably the directions).

I can store single maps if I'm not in directions preview, but can I do it while I'm previewing directions?

I found these posts with many alternatives but first I'm looking for a solution in the Google Maps app itself.

Weird internet connection problem
My friend just had an internet connection problem. Her handphone (Acer Liquid C1, Android OS maybe 4.0) have a problem in the connection. It could connect to Line application and chat normally, then it could read and reply some mail in Gmail. Also she can refresh feed on Instagram.

But, it's BBM (blackberry messenger) couldn't chat normally (in this case, my BBM message just sent to her's [appeared as a tick], but not delivered [not appeared in D] to her BBM).

The other problem in this case is:

when the handphone connect to a mobile hotspot from apple / blackberry device and wireless router from apple, sometimes the device (my friend's handphone) is disconnect from the wifi after exit the setting menu. But when she open the wifi setting menu, the handphone is connected.

But, when her handphone connect to a mobile hotspot from android device (in this case, the mobile hotspot is asus tab and samsung smartphone), the device is always connected.

Another clue in this case is, when her android access play store and trying to download an app like Twitter with mobile data or hotspot from apple device, it always give an error code like 4xx or 9xx (I forgot this, but the first number is correct). But when it connect to wifi (from android mobile hotspot), it can download the application.

If someone can solve this, my friend will be glad :D

Sorry for my bad English :(

Samsung Galaxy Note 10.1 - 2014 Edition (Chinese version)
I live in China. Just purchased a Samsung Galaxy Note 10.1 - 2014 Edition (SM-P600) tablet. Since I have other devices that came with Google Play Store, I had no idea that Samsung's wouldn't.

I was wondering, is there a way to get Google Play installed and working on this device? Is it possible to purchase the Samsung/Google version and replace the Samsung/Baidu one that it came with? Or, is there some other workaround for this specific issue? I live in China, and so I don't have many options to buy products designed for Westerners.  Hope someone can offer some assistance.

问:
If I upgrade from Android 2.x to Android 4.x should I re-partition to make use of MTP?
Original article: Please explain the android partition structure to me?

This partitioning scheme as become somewhat less common since Android migrated to Media Transfer Protocol for providing access to the storage from a PC. The reason the separate partitions were originally necessary is because Android used UMS in the earlier versions (anything <3.0), which requires block-level access to the storage space, meaning Android had to unmount the storage space that it provided to the PC. A consequence of this was that the entire partition could not be given to the PC because Android would basically cease to function until you unplugged your phone if it did.

If I now upgrade my ROM from Android v2.x to Android 4.x should I do something to take advantage of Media Transfer Protocol? (I'm talking about custom ROMs and rooted phones).

Post-rooting: updating Android and modifying system files?
So at last I rooted my tablet (without a custom ROM). Then when I checked for new updates I received the message "Your device has been modified" so I don't get any new updates. So my first question is:

1-Can I update the operating system (and not the firmware) myself?   My kernel version is 3.4.0.

Now since Android is a Linux-like OS, I expected to be able to tweak the system by editing the files in the /etc folder. For example I hoped I could manage app permissions this way.  But when I open the files on /etc/permissions or /system/etc/permissions I don't understand much. So:

2-Is it a good idea to modify system setting files and if yes, is there any (official) reference manual?

Can the Mobile Management facility of Google Apps For Business be used to control which apps are installed from Google Play?
Am considering buying Google Apps For Business to improve management of a large number of Android devices.

We will provide an app that we have created to our users through our private channel. We do not want users to install any other apps unless we have authorised them.

For example, we may wish users to have WhatsApp but not Flappy Bird 2.

Android virtual keyboard pop-up issue on focus
We are using a web app (built for desktop) in Android tablet (Motorola ET1). Issue is that android soft keyboard is popping up whenever focus goes to a text box.

On page load, focus is set to the text box but keyboard is not popping on page load. Users scan input data using tablet's scanner into this text box, we take scanned input and submit to the server. If the transaction is successful, text box gets cleared and focus is set in this text box to scan next input. when focus is set this time, android keyboard is popping up.

I tried using blur to prevent keyboard popup, it prevents keyboard from popping up but focus is not in that text box so user cannot scan the input data.

As an option, I installed null keyboard on Android tablet and provided jquery keyboard (https://github.com/Mottie/Keyboard/wiki) to enter input data if they want to enter data manually. This option seems to work technically but this shuts off the keyboard for entire tablet and users have other apps on the tablet so they are not happy with this solution.

We are using dolphin browser in this tablet. Dolphin has cordova plugin to get an access to device's native functions. But I don't see anything related to keyboard. Also I am not finding any reference in HTML5 documentation also.

Can you please suggest if there is any solution to this ? Please note that our application is a standard webapp and not built as Android app. Thanks.

Motor disability – In Android Home or “All Apps”, tapping on right edge = swipe to the left – Tap bottom in Chrome = swipe up/page down?
Microsoft has the Sticky Keys accessibility option so that you don’t have to hold down a modifier. Too much holding down, like in mouse dragging, and swiping on a touchscreen can be bothersome for people who suffer from a repetitive strain injury, or other people with motor disabilities.

On the Android Home screen or “All Apps”, tapping on the right edge = swipe to the left, which moves you to the next screen on the right.

When browsing Chrome, or YouTube, is there a way that you can similarly touch somewhere near the bottom edge of the screen to execute a swipe up (page down)? Perhaps an accessibility option can be turned on to add a page down button in the Navigation Bar?

It would be like browsing a webpage on the desktop, and instead of just tapping the space bar, or page down buttons, you have to keep swiping upwards on the screen.

Thanks.

ZTE Nubia Z5 Problem?
I have a Zte Nubia Z5 ("2nd Hand") with a software camera problem (I think is a software problem because the camera works sometimes)

The phone has Android 4.1.2. I tried to hard reset the phone but I just got a white screen. And I tried to enter into Recovery Mode and get the same white screen. The phone in adb devices is recognized as "NX501 Recovery". Normally is in "NX501 Device". That means something in the Recovery NAND or something I do not know is bad.

The phone was normally working fine, since my brother installed Chainfire 3D and is stuck in the boot logo, a normal tune is heard as normal like its entering in the OS. But still stuck on the boot logo. I read that is a Chainfire 3D problem in some devices.

So I start to try To install some custom recovery CWM, TWRP etc. It was difficult to find a Recovery because all the information you can find on the internet about this phone is in Chinese and Russian.

I did find a TWRP Recovery (Also a CWM too), but both in Chinese. I tried to enter in boot-loader mode to install the custom Recovery. The phone does go into the the boot-loader and gets recognized as a "Sooner ADB Device", but in ADB does not get recognized. With ANY of the ADB Drivers, ADB Composite, ADB Interface etc.!

Disable GIFs system-wide or by app
I was wondering if there is some way to:

Disable GIFs from loading, and/or

Disable GIFs from playing on an Android device.

The first would be mostly to conserve data, especially if I'm on Tumblr or a similar site where GIFs feature prominently. The second would be for accessibility (for example, a friend who is epileptic).

Maybe it could be done through editing the app, or through an Xposed module?

If it helps, I have a Galaxy S4 Verizon, rooted.
