DropBear dropping connections
I've got DropBear II installed on my android and my public key uploaded. But when I connect with my key, it closes the connection right away:

```<code>jlaptop:home jim$ ssh 192.168.1.14 -i android.key
Welcome to DropBear SSH Server II!
Connection to 192.168.1.14 closed.
jlaptop:home jim$
</code>```

What could be causing this? I tried SSHDroid before this, and as soon as I would successfully authenticate, it would drop the connection too.

EDIT:

问:
Folder hierarchy messed up after upgrading my phone to Jelly Bean!
my HTC Desire X recently got an update to JB 4.1.1 but after the update, the folders are not getting diaplayed in their original hierarchy in the music player apps like PowerAmp and also the default HTC Music player.

Like lets say I have three folders A, B, C and they each contain three more subfolders A1, A2, A3, B1, B2, B3.....

But in the folder view of PowerAmp, all the folders are listed recursively in a single list e.g. A,A1,A2,A3,B,B1,B2,B3,C,C1.C2,C3!!! Also note that in this case the folders A, B and C are only containing files other than those three subfolders.

I initially thought this was an issue with PowerAmp but since it's happening with the default music as well, I came to a conclusion the issue lies somewhere. Any way to fix this?

How can I easily copy files from an Android device to a computer wirelessly via command line?
I need to copy jpegs from an Android phone's sdcard to a computer, ideally through command line (/storage/sdcard1/*.jpg to a remote location)

I've tried Izzy's solution from this post like so:

```<code>scp -p -P 2222 root@192.168.1.19:/storage/sdcard1/*.jpg ~/Desktop/pull/
</code>```

but got this error:

```<code>sh: scp: not found
</code>```

The scp and ftp commands are missing on the device, so is there a way to get this working ?

I've also looked at busybox and had some success doing so:

```<code>cd /storage/sdcard1 && for jpg in *.jpg; do ftpput -u user -p pass 192.168.1.33 ./Desktop/pull/$jpg $jpg;done
</code>```

Another thing that worked is this ls solution but for single files and I'm not experienced enough with bash scripting for this to work on multiple files.

I'm looking for the simplest solution (with fewest install/setup steps).
What is the easiest way to do this ?

Google Books errors on HTC Sensation on application launch
Google Books Android crashes on loading, and whenever I have auto-sync enabled (which is hence very disruptive)

I always get the error twice:

The application Books (process com.google.android.apps.books) has stopped unexpectedly. Please try again.

The actual stack trace shows the error to be:

java.lang.RuntimeException: Unable to create application com.google.android.app.TabletBooksApplication: java.lang.IllegalStateException: Expected a directory for path: /data/data/com.google.android.apps.books/cache/logs/null_account at android.app.ActivityThread...

I didn't consciously choose to install this application, it just seems to be part of the android application set.  I'm assuming the null_account bit is the problem but have no idea how to go about correcting this.

Can we get a set of Android devices to update/ sync at once?
Within the school where I work there is a mix of Android and Apple Tablets. We use Apple Configurator for the iPads and are wondering if there is a system out there which can do the same for the Android tablets?

We can either connect to them through the charging cabinet or over a wireless connection.

Any suggestions would be appreciated. We would prefer a free option, though prices aren't really a deal-breaker.

Installing a fresh copy of Android on my rooted Galaxy Tab 10.1 2
I've got a Galaxy Tab 2 10.1, which has been rooted, though it's still stock firmware. It has a whole bunch of problems right now with certain apps, e.g. it currently can't play any music (player crashes) and various other apps are pretty flaky. Anyway, I'd like to restore it back to stock, on the latest firmware. I'll probably root it again at a later date, but for now I'm not too fussed.

I've tried using the in-built update functionality (i.e. the "a new update is available" feature) but it reboots into CWM recovery and says that the signature verification failed.

How can I go about resetting the device, clearing out the junk, and updating it to the latest firmware? I'm not particularly fussed about any of the apps or settings that are on there.

How to force my tablet to remember which video files it was playing and make it easy to resume playing these files next time device is powered up?
I am using Samsung Note 10.1 to watch lots of instructional videos; each course is composed of 10-40 video files, stored in folders, subfolders etc

I have tried bunch of video players; most of them can play videos ok, but once the device is rebooted I have to do the whole process again (start video player, point it to certain folder, scroll through the files I have seen already etc)

Here is my question - is it possible to force video player to start playing from the last position the player has been stopped at? (and later been able to jump to the next file from that folder etc)

As an alternative fix - would it be possible to switch my tablet into "deep-sleep" (hibernation?) mode so it could stay in such mode for a long long time without draining the battery and, once waken up, restore last work session)?

Video Player with support for audio channels?
I have recorded a TV show with dual channels (left is dubbed, right is original voice) and then converted into a mp4 file. The movie plays fine in VLC where I can choose the audio channel I want to listen too.

On my Galaxy Tab the movie plays fine too (with several apps: the built in Video app, Rockplayer, Doubletwist and Vplayer), but I haven't found a Video app that lets me choose the audio channel; it's a little difficult to watch the movie with two difficult audio tracks in your left and right ear...

Are there other apps I could try? Or is there some utility that would let me redirect only the left or right channel to both ears?

Acquire and image of that block device with dd: dd if=/dev/<blockdevice> of=/sdcard/image bs=4096

3.Get a data recovery forensics tool and let it search /sdcard/image for the lost file. You can of course try to run multiple tools on the image. Formemost and Scalpel are a good start.


问:
Required to Reboot my Android Device Every Week?
When I got my first Android phone (the rugged HTC Inspire), I was told that I should restart the device every week. The rational, which made sense at the time, was that it's a small computer and every computer needs a soft reset, right? Over time, my phone needed it from continual app crashes but it took forever to do so. Overall, it did help to restart

I've recently upgraded to the HTC One and, from what I can tell, I don't need to restart this thing every week. It's run for a couple weeks on end without problems (one app-hangup what wasn't fixed with a restart) and although my usage isn't intensive, it's getting heavier.

Is it a good idea to restart my Android device after a certain period of time or does it not do anything at all. I'm not so much worried about harming the device but just keeping all of my info current without needing to open up half-dozen apps every time.

EDIT: Sorry if this comes as a duplicate question. I tried looking around for other answers but my particular question related to normal/periodic rebooting not related to a slow-down of the OS or other apps. Most questions regarding rebooting of an Android device revolved around either a slow OS or apps hanging and not necessarily answering my question.

Why is my Xperia U slow?
I have a Sony Xperia U running Android 4.0.4 ICS. The problem is that it runs really slowly. It is particularly bad while multi-tasking. While listening to music, if I get a phone call, it hangs. Vibrator starts but the ringtone doesn't. The "Incoming Call" screen doesn't come up, etc.

Has anyone used this phone with Gingerbread? If so, how was their experience?

I followed the steps in here, but my Battery Monitor says 43% Screen and 23% Android OS, which isn't really helpful! Are there any particular apps that are responsible for this?

Why is ICS slow on this device? I mean, 1.0 GHz dual core and 512 MB of RAM is not less!

edit: The first thing I did after buying it was to upgrade it to ICS via Sony PC Companion. The phone has been like this ever since. I phoned Xperia Support and also did a Firmware Repair (again via PC Companion) and a Factory Reset, but it's no use.

问:
Should I upgrade my Samsung Galaxy 2 II 4G Epic Touch with Kies or the Simple Upgrade tool to JB?
I currently have a Samsung Galaxy 2 II 4G Epic Touch and I want to upgrade it to Jelly Bean. After looking at some support pages on Samsung's website, you have two options to install the new version: Kies or Simple Upgrade Tool.

Which should I use? Kies seems to be easier to use, looks better (not that that matters or anything), doesn't need to be installed (as far as I can tell), has a backup/restore feature, and you don't have to have a full battery or have to mess around with the battery before installing. Is one newer than the other? Does one save more data/settings?

By the way: what will I lose when upgrading? I know it says to back up. How about: favorites, text messages, call history, settings, app data, home screen shortcuts/widget placement, etc. I know I can most likely save notes, photos, voice memos, contacts, emails, etc, but am I starting out with essentially a new phone running Jelly Bean and the basics that I backed up? How will this compare from Kies to Simple Upgrade Tool?

Will it keep everything the same, even if I do have to use a backup Samsung recommended with Kies to have in case something went wrong? Or does the backup have a image of the before that I can revert to and be the same as before if something went wrong so I could start from the beginning again?

Galaxy S I-9000 v2.2 contacts disappeared and home screen blank
Yesterday, I picked up my phone and saw that the screen was black and unresponsive, also the lights on the two soft keys in the bottom were lit up. I tried tapping those keys and also the lock key but nothing changed so I took the battery out and restarted the phone. Then I saw that all my homescreens were blank except the first one which had google search widget(wasn't there before) and some other default widgets.Also the contacts stored on the phone were gone (google contacts and sim contacts are there).

In addition to those, my lock animation (the one that says "slide the glass") is gone. Now the phone opens up directly to home screen when I press the lock button. Also, the home button does open the screen light when the screen goes dark, but it won't get me to my home screen. One more problem, the menu which is displayed when you press and hold the lock button used to have 4 items (power off, data network open/close, silent mode open/close and flight mode open/close) but now it only has 1 item (power off). The last one, my phone seems to be giving the busy tone to anyone that calls me. I can call anyone with no problem but I can't receive calls. Text messages are fine too.

What can be the cause of this? Has anyone had any similar problem. btw I never messed with the roms or root or anything. I've been using it with the stock rom since I bought it.

The most important thing is the contacts that are stored in the phone. Can I recover those? If so how?

Thanks in advance.

Would Non-Open Handset Alliance Android phones have Google Now?
I understand that whilst Android is free and open source, in order to use Google services, an OEM has to be approved to join the Open Handset Alliance (OHA).

One of the biggest additions to Android for Jelly Bean was Google Now. Just wondering, if I buy a non-OHA phone, does that mean it won't come with Google Now? If so, what will be in its place? Will it just be the old Google search app?

The other thing is, can non-OHA phones run Google services that are embedded into apps? For instance, if an app uses Google Maps, would it still run on my non-OHA phone?

I do not want this feature, but it gets unintentionally activated by my cheek (which manages to press the "Yes" button of the popup too!) when I'm on calls. I've missed several calls from friends and relatives due to this.

So, is there a way to disable this feature? I've googled a lot, but there are only posts about how to remove people from blacklist after they get added there, nothing about how to prevent this whole mess. I don't want to be checking the blacklist every day to make sure someone new hasn't gotten added that day, so I hope there's some setting somewhere to disable this function.

How to change Android's primary Google account
During the "in-app purchase" I am unable to switch the Google account I would like to use for "in-app purchase".

Currently, in order to change the primary Google account on Android operating system, we have the following ways:

Perform factory reset on our devices.

Remove other Google accounts, leave only one Google account.

If we perform factory reset, we will lose all data that we have not backed up or unable to do backup. And, we have to re-install the applications that we need to use.

If we choose to remove other Google accounts from our systems and leave only one Google account, if there are applications installed from Google Play Store by using the Google account that we want to remove from our systems, then we will not be able to remove the account from the system unless we remove those applications. However, sometimes we may forgot which account we used to install an application from Google Play Store.

My question is that is there any other way to switch between the accounts?

AFWall+ is not blocking apps
I've used AFWall+ to block Weather Services Pro from using my data plan, but My Data Manager app still shows it in the top 3 of data plan use.  Is there some background process using data that isn't being blocked?  Is there some other way to block it from using mobile data but still work on Wi-Fi?

HTC Vision/G2 with CM7.2.0 Android 2.3.7

Update: I found an FAQ:

How do I know if my phone supports iptables?

Issue the following command in ADB shell or in Terminal Emulator:

```<code>iptables -L -t nat
</code>```

```<code>$ su
# iptables -L -t nat
Chain PREROUTING (policy ACCEPT)
target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

Chain POSTROUTING (policy ACCEPT)
target     prot opt source               destination
</code>```

Is that correct?

Also this might be the issue, though I don't know how to prove it or troubleshoot it:

AFWall+ does not work under CM 7.x, how can i fix this?

CM 7.x uses old version of iptables which has conflict with AFWall+ built-in iptables. As a workaround you can try to update your iptables to the latest version. But it should work without it. Contact developer/raise an issue on github.

Also, I enabled the "Fix Startup Data Leak" option, and after a reboot, nothing could access the internet at all; it could connect to Wi-Fi but the icon was white indicating no internet connection.  Then I went into AFWall and pressed Apply, and stuff started to work.  Now I can block Browser and when I try to load things in the browser it says "Web page not available" as expected.  So maybe it's working now?

Also firewall log is no longer empty:

```<code>AppID : 10080

So I think that fixed it.  Weather app says "request timed out" and Facebook says "Network Error", but Gmail etc still work.  :D  If it works over the next few days I'll move this into an answer.

Music playback stops randomly
I have bought the Xperia ZQ (Xperia ZL's alias in Brazil) C6503. I am experiencing a very annoying problem: from time to time the audio playback in any audio app just stops. If I hit play again it will resume normally but I still need to tap the play button which can be a pain specially while driving. I can't remember when this started but I think it is from the first time I tried to play any audio on it.

I think it is an issue with 'Audio Focus' since the playback pauses and will resume gently from where it stopped if I hit the play (or unpause) button.

I used adb logcat to register the events logged by the OS while listening to music. When it happened I checked the log and found these lines (which I think represent the moment it stopped playing):

```<code>D/PowerManagerService( 581): acquireWakeLock flags=0x1 tag=NetworkStats
D/ConnectivityService( 581): Actual State: DefaultConnectivityState, Current State:DefaultConnectivityState.processMessage what=113

</code>```

I was using n7 player (which I guess is com.n7p.atj@425206b0 in the log) when the playback was interrupted. I think that I/AudioService( 581): AudioFocus requestAudioFocus() from android.media.AudioManager@426dc7a0gu@42659da8 did interrupt the n7 player.

I'll try to get more events like this using other apps. Anyone have any clue on how to solve this? I thought I would find some lousy app requesting audio focus randomly but what I got here is AudioManager messing my playback... (assuming I did interpret this correctly).

Thanks in advance for any help.

Can installing a modem help with the GPS of Samsung Captivate?
Like most Samsung Captivate users, I find the GPS hardware in my phone to be unsatisfactory. I have the impression that the actual GPS signal is pretty much useless and the phone (Samsung Captivate) gets location via wifi signals only.

I heard that you can flash modems to improve the GPS. They are often posted on xda-developers without much information for newbies, like here. Since I've never done it before, I thought I would ask for some information. Can I just choose a modem and install it on top of the custom ROM that I'm using? Or do I have to get a ROM that has the correct modem inside?

This is the rom that I'm currently using which works fine for my device.

How is USB debugging mode related to root detection?
I have a game in my Samsung Galaxy S2 (i9100) that if it detects the phone is rooted, it terminates. My phone is rooted but I still can play this game using OTA RootKeeper to temporarily unroot the phone.

I would like to use some apps that required USB debugging mode enabled when I play the game, however, the game terminates as if it detects the phone is rooted.

I have some friends that they can play the game with USB Debugging mode enabled (although their phones are not rooted). So I bet it's because USB debugging mode enabled would do something affecting root detection.

How does the USB debugging mode enabled affect root detection and how to solve that?

In particular, imagine the following scenario:

A program on the laptop magically moves the e-mail to a spam folder.

Exotic case of Galaxy Nexus not booting
Symptoms :

Put battery into Galaxy Nexus (tried with two different including a brand new one)

Plug cord to USB host or charger

Large battery charge indicator icon appears in the middle of the screen

Six seconds later the screen goes dark and no further user-observable activity happens

During the whole process, device does not react to any button input - including the 'while holding down Volume Up and Volume Down buttons together, hold down the Power button for ten seconds' maneuver that should have taken it to fastboot mode

When plugged to an USB host, no USB activity is detected from the host - whether by adb or other USB observation tools.

Context :

The device having suffered a cracked screen, it has been swapped for a new screen

This problem appeared on first boot attempt after the screen swap

The device worked perfectly before suffering the cracked screen

The appearance of the battery icon proves that the replacement screen works

I may have broken something during swapping the screens... But with disabled hardware I would have expected a frankly non-functional device.

Why do people recommend to flash a ROM or an Odin component (PDA, Phone, CSC) at least two times?
In XDA, I often see people complain that they flashed something, and it doesn't work. Then, somebody tells them to try flashing it again, and it works! What's the reason behind this?

I imagine this to be something related to dependencies, like in SQL. Ideally, a child table should be deleted first before the parent table. If you had a batch SQL statements in this sequence, you'd have to run the script twice. The first run would not delete the parent table (because the dependent child table still exists), but would delete the child table. Then, the second run would eventually delete the parent table. Is this the same analogy that's happening when flashing ROMs twice (or more)?

Yesterday the device just started to turn of the screen without locking the phone and before screen timeout, and it just won't stop !!!

I tried to change the screen timeout duration, didn't work, I stopped the Galaxy S3 feature smart stay and set it back on again and again and it's not working, I googled this problem and I can't find anything related..

I only have one option to do, and I wish I'm wrong, which is to do a factory data reset

I'm afraid that there might be a problem in the power button, again I hope I'm wrong.

Please any help is very much appreciated ..

Samsung Galaxy S GT-i9000 - MicroSD Card not recognized
My Samsung Galaxy S GT-i9000 rebooted unexpectedly and when it came back up all my app symbols showed a grayed out android image with SD written in the bottom right corner.

All my music was gone too. I went to check under "SD Card and Phone Storage" and under "Storage Settings" it said "Mount SD Card". I clicked on "Mount SD Card" and it turned into "Mounting.. Mount in progress" but nothing happens (15min).

I tried powering off the phone and removing the battery and SD card, putting everything back and powering up again, but no success.

I also tried a Factory Reset, the SD Card is not recognized.

I inserted the SD card into my friends Samsung Galaxy S2 and it appeared on his phone and he could copy pictures and music to it, but on my i9000 the card does not appear.

What do you suggest i do?

Meaning of purple blinking on Sony Ericsson Play (R800)?
The phone went off and I cannot turn it on. I tried pulling battery out, but it did not help. Cannot also connect it to SEUS since it does not detect a mobile connected.

Now, when I connect a mobile on USB charger and press the power button, the screen quickly blinks for less than 1s and then then purple light keeps blinking (flashing).

The purple light is coming from the LED on the power button. When I connect the charger the screen first turn to green, I think. And when I try to turn the mobile on, the screen turns to purple blinking light.

what is the meaning of the purple light? I cannot find the meaning on the Internet.

How to disable backlight buttons in MTK 6577 phone?
I want to get in control of the backlight for my phone buttons (It is a Runbo X5, MTK6577 based).

According to some tutorials I found, I should edit the content of this file:

/sys/class/leds/button-backlight

that is actually a link to this one:

/sys/devices/platform/leds-mt65xx/leds/button-backlight/brightness

I "cat"ted the content of the file when the backlight was off and on, and I read values of 0 and 255 respectively.
So far, so good: that file must be involved somehow then.

Now, all the documentation I found (for instance this one) states that I should manually change that file content according to my will (for instance, 0 if you I the lights to be off), then making the file non-writeable; so that the system can't override the settings.

I did, and it did not worked. Now the file content is not overridden; it stays fixed to 0. However, the button keep getting lit as if nothing changed!

I have the feeling that "/sys/devices/platform/leds-mt65xx/leds/button-backlight/brightness" is just where the information about the backlight status is written but not where it is set, at least here on my unit (that is, a Runbo X5 phone).

Any help would be greatly appreciated, I really want to turn those darn lights off at night.

Thank you!

tasker: grace time on events
I use tasker to act on state change on wireless services (WifI on, Bluetooth connected, ...).

There are cases where, for a very short time, the state of a service changes (no matter the reason: a thicker wall, repairing of BT, ...) and the exit actions are triggered.
This is particularly annoying when I rely on continuity (I have, for instance, Waze being killed when the connection to my car's BT is over - but the car sometimes requests a repairing out of the blue and Waze is killed -- which by the way never happens on a 120 km highway section but always right on the middle of complicated turns in a city :)).

What would be the best way to configure a "grace period"?

```<code>when an action is triggered (say, by BT disconnecting)
  wait for *n* seconds
    then if the state is still there (= BT is disconnected)
      go ahead with the actions to perform
    otherwise
      do nothing
</code>```

I know that I can add the logic above to selected actions but this is cumbersome and prone to errors (a short cut may trigger an exit action, then immediately after an entry one, while my timer on the exit one is still running). It would b better if the "state" of a service was aware of the possibility of these short interruptions (and therefore manage correctly the exit and entry actions)

Thank you for any advice

Has anyone heard of a "Coin mode"?
Someone asked me how to get out of "Coin mode" the other day. The user in question may have misunderstood a prompt or been confused as I was unable to reproduce the specific error. However there definitely were errors. I have never heard of it, and would like more information on it if it exists. Connecting with a wifi network seems to have resolve the issues, however if that was the issue, it should have corrected itself using the data connection via mobile without intervention. It is my guess that "coin mode" may have been an error given by an application rather than the OS?

It had stopped working as normal after several months of standard behavior. Supposedly an icon of the Android-guy came up and said device was in "coin mode" or something similar.

The device was a Samsung Nexus phone running 4.2.1 which must have been pushed onto it as the user would not have modified her own phone herself. The time became messed up, and the last system update was listed as in the year 1999. The tool-bar on the top was also messed up. The device had several other glitches, including the backgrounds not properly updating when in applications such as Google play.

问:
is it possible to emulate previous OS in an Android Device?
Well, I see no one else have asked this, may be a dummy question, but is it possible (through a menu setting or an app or something) to emulate a previous version of Android OS?

For example, my device is running ICS 4.0.4 and I want it just for a moment to try an app have it in GB 2.3.6 or GB 2.3.3 or even further?

I know about the AVD (Android Virtual Device Manager) but it's just that is not smooth enough for me, that's why I want it in a physical device.

Any help is appreciated.

UPDATE:

I'm not worried about if an app is supported or not, I'm a developer and what I want to test is the behavior of an app I'm building in different versions of Android. Since I have JB, I want to try my app in ICS and GB to see how it works, minimal details such as action bar that was added in HC. That's why I ask if it's possible to do it with my own device or if I have to get other devices with previous OS

问:
Is there a way to obtain temporary root (until next boot) on a locked HTC device without S-OFF?
Let's say I want to run some app requiring root access on my HTC Droid DNA (2.06 stock firmware, 4.1 Android, NOT broken, meaning it's S-ON).

My (somewhat naive) understanding of S-ON/S-OFF is that it write-protects the ROM, and thus makes writing anything into it impossible (such as whatever changes are needed to install root that persists from boot to boot).

The question is, is there a way to obtain temporary root without breaking S-ON, such that it only persists till next boot? (with the understanding that any changes to filesystem made by the need-root application that would have been saved into protected parts of the filesystem would ALSO be lost after reboot).

P.S. Please note that the question is about technical detail about rooting - asking me to clarify which app I need to run to help me do the same task without rooting is entirely off-topic.

Unlock ASUS Transformer Tablet
My ASUS Transformer TF700 worked fine and I did not put in any unlock code to open it.  One day the initial screen showed a keypad and invited me to put in the unlock code.  I read you can simultaneously push the power and volume buttons and do a "WIPE" that takes it back to Factory Default Settings.  I have tried this repeatedly- holding for 5 -  20 seconds -since some postings indicate that 5 and 10 seconds bring different levels of "wipe."  I have not had any luck with the ASUS Website.

I know this is pretty simple compared to all the "Super Geek" stuff I see on this site.  However I can not even aspire to be a "Mediocre Geek" if I cannot unlock my tablet.

once it goes off because battery didn't have enough charge , when i re start it again it come up with the basic settings just like it's the first time that the Rom is starts and all the customizations i made were gone
it runs a basic wizard that asks for basic settings and then when i check for those apps i had installed before they weren't there. also i check to see how much of the internal memory is occupied , i found it just 32M (or sth) just like there's no app installed on it

I'm wondering whether i could get back to all the customizations I've done on my phone or get all those apps back to my phone ?

it's very upsetting that every thing goes wrong this way... :-(

Huawei u8800 restarts
I am having troubles for weeks and still can't do anything

I can only go into Android recovery, and can wipe data. Then after 2-3 restarts, Huawei X5 boots. If I restart phone, a lot of windows showing stop activities shows. I can't even click restart button.

So, I put 2.3.5 first, then Gingerbread "custom app" to download in external and internal SD. After wiping in Android recovery, I power off. With + - and power, I made it update. This time, updates were successful. Before, it was always failing.

It could make updates. But after updates, it could not start again. After loading Huawei logo, it restarts and can't go to homescreen. So, I had to go to Adnroid recovery again and wipe data.

I can't change recovery because I can't install superuser. Superuser should be restarted, but if it is restarted, phone can't start.

I can only use SD card, after wiping data, until one restart. How can I change without rooting recovery? And I change recovery, does this help? I don't know what the problem is.

In my sd card, there are dload s, aurora 4.0 s, cyangane , partition zip and like that a lot of zips but in android recovery , when i try to install, it fails. Only i can install in update mode (Volume up volume down and power), the one in dload file.After updating that (to 2.3.5.), it restarts 1-2 times maybe, then i can go into desktop and settings. But if i restart again, it breaks. I am bored of this. What is wrong with phone? I downloaded a lot of dload files, maybe i am not using the proper one.

Galaxy S4 Video Recording: File Size Limit & Frequent Blurring
I'm trying to use Galaxy S4 as a video camera for recording offline usergroups. Apart from whether it's a good idea, it's generally succeeding, but there are some critical problems:

Android file system does not support files larger than 4GB. At 1280x720 resolution, this is about 40-something minutes, which is sometimes less than what I typically need (some sessions take 60+ minutes), which causes a sudden video stop, and if I'm conscious enough, I press the recording again, and lose about a minute or less in between.

I'm thinking this problem might be solved by rooting the phone and buying one of the programs that allow mounting NTFS for Android, formatting an SD card as NTFS as well. Would you expect this to work? Any luck with any of this programs and recording to memory card?

Sometimes the phone blurs the text it records and afterwards the text becomes clear again. Sometimes this happens quite often that it becomes annoying to anyone watching the video. I have tried disabling video stabilization but this doesn't seem to improve it much. It still insists on blurring text at random times. It probably is trying to help me with some autofocus thing, but it's only doing harm.

I'm short of ideas for this one. Anyone managed to stop it?

Not sure if this should be split into 2 questions, but would appreciate help on either anyway. Thanks a lot.

Sporadic SMS on Galaxy Nexus after upgrade to 4.3?
I have an unlocked Galaxy Nexus I bought directly from Google and use a T-Mobile plan. Last week, I got the OTA update for 4.3. Since then, I haven't consistently been able to send text messages. The usual scenario is:

Send a text message.

It hangs at sending (Messaging eats up more battery than normal during this.)

It'll sit there indefinitely until I send another text. Tested this by waiting all day on two occasions.

After I send another text, either a.) that one hangs too or b.) that one, and any ones that are stuck at sending, will all simultaneously send. It's like the successive text wakes up all the other ones.

This happens enough to not be coincidence, and as I said I've let the stuck messages sit there for about eight hours without sending any more messages and they would not send until after I did. Anyone have any idea what's going on here?

```<code>mount -o rw,remount -t rootfs rootfs /

Samsung Galaxy S4 here. I found that my phone often switches cell towers through an app called GSM signal monitoring. I don't know if this is the phone's fault or not, but the most annoying thing about it is that when the switching happens any and all data transfer are completely interrupted and stopped, and are unable to resume even after the switching is done. This happens whether I'm mobile in a car or stationary sitting on my desk. I could be downloading 100 KBps and just completely stop and I have to restart the download all over again. Is there a way to stop this from happening? Maybe lower the tolerance on which the decision to switch is made? </p>

Changing (Forcing) Screen Resolution on OUYA
OUYA doesn't provide any built-in (UI-based) way to change or force a resolution. This is a problem for some (like me) who have no HDMI devices, and use HDMI to DVI adapters, or simply have devices which do not correctly display the best resolution. (For clarity, OUYA defaults to 640x480 if it can't display a higher resolution).

To clarify, I'm using a 20-something inch "normal" monitor (no HDMI input), so I see very pixelated writing that's hard to read in the OUYA menu. Some games, like Final Fantasy, appear to display decently though.

This XDA Developers thread found two methods that works for some OUYA users. It's not clear if these actually change the resolution though.

Method 1:

cat modes displays all the possible display modes. (cat mode displays the current mode.)

echo 0 > /sys/class/graphics/fb0/device/enable

echo (videomodefrommodesfile) > /sys/class/graphics/fb0/mode

echo 1 > /sys/class/graphics/fb0/device/enable

Method 2: Run am display-size (resolution). For example, am display-size 1080x720 should change the (virtual?) display size to 1080x720 px. But other users in the same thread report that this causes other display issues, like shrinking the display.

Is there a consistent way to change the display resolution?

How to make notification lights turn off automatically when new email is read from another platform?
I'm using a Samsung S3 and I currently have the notification LED indicator option ON when an email arrives.

Is there a way to make the flashing blue light stops when I read this new email from another platform (Thunderbird for example)?

For example: Unread new email inbox : Flashing
             New email recently read: Stop flashing

Thanks!


问:
What would be a good method to find popular, low rated apps on the google play store?
Apart from just scouring through the charts and clicking on each app individually. I calculate that would take a full week to complete.

I can't find any site that lets you sort the apps by rating, making this tough to achieve... if it's possible at all.

Thanks!

ProxyDroid says it connects, but won't access the internet
I'm trying to get my schools proxy to work through ProxyDroid on my Galaxy S3 4.1.1. I can use the proxy fine through the default settings application, but that only allows me to use my browser, no applications. With ProxyDroid I can't even get my proxy to work on the browser, much less any other app.

To use my dorm's WiFi (and ethernet) I am forced to log in through the proxy. I'm not sure what the problem could be. I've got the correct url (I also have a proxy.pac option, but it ProxyDroid woudln't read it) and correct authentication.

When I enable the proxy in ProxyDroid it says it connects fine, I just can't access the internet.

I am rooted.

USB Tethering Problem
I am using USB Tethering to use my phone as a modem. Whenever I activate USB Tethering, there will be two network present in my PC. One named Network X(X being a number which is incremented every time I connect. Currently it's 13.), another named unidentified network. On basic Network section, it would show multiple network and there is no access to internet.

To use internet, I have to disable Local Area Connection 9 and then enable it which removes the unidentified network. Now I can use internet. I have do it every time I want to use Tethering.

My Handset: Sony Xperia Tipo

Android OS: Ice Cream Sandwich

PC OS: Windows 7

What is the cause of this and how can I solve this problem?

How to restore memos on Samsung S2
I have used the memo app which came with Android (the one with the big "T" logo) successfully for years. Today it suddenly lost all my memos without warning. Is this a known bug? Is there some way to restore the memos? Where are they normally stored?

I haven't synced with Google for a while (it seems authentication changed after upgrading to 4.1.2), so that option is not available.

I haven't installed any new apps since upgrading to 4.1.2 (and the Memo app did work successfully for a while after upgrading). I have disabled some apps which I have never used (at least not directly):

ChatON

Clock (digital, funky and modern)

com.google.android.voicese... (I can't seem to display the rest of the name)

Dual Clock (analogue and digital)

Exchange Services

Face Unlock

Game Hub

Google Play Music

问:
command line mtp android sync with pc
I'd like to be able to sync a directory on my android phone with a directory on my pc from the command line over a usb cable without installing anything on the phone.

This can be done using adb shell ls will give you a list of files on the phone, push will copy files from pc to phone, pull will copy files from phone to pc and rm (or rm -rf) will delete files (or dirs) from the phone.

However, adb push is slow (it takes me 5x to 10x as long to copy files to an android phone using adb as it takes to copy files to an iphone using itunes).

There are pc apps which will sync (e.g., pure sync or, for ebooks, calibre), but that's not command line. Calibre seems to include python source for an mtp driver, but it's overly complex (for me).

Is there anything better?

BTW, there are many similar questions on various stackexchange sites, but I haven't found any which answer this question.

问:
Can I use an old phone as a bluetooth headset and dialer?
I'd like to use one of the new 7" tablets that will have cell service as a phone. I would like to leave it in my backpack and use something smaller to send and receive calls.

I think I should be able to recycle an old Android Phone for this purpose. I figured there is some kind of Bluetooth stack (Bluez?) that just needs to be configured the right way. The hardware should be all there. The best I could find thus far was this question and the links therein.

I saw some dedicated devices on Alibaba that do this; and I have seen people do this in China. But I haven't seen any such devices in the US. I could settle for a dedicated device, but recycling an old smartphone would be more useful.

Rooting nexus 4 failed
I was trying to root my nexus 4 by the following steps:

Download and copy the file UPDATE-SuperSU-v1.43.zip to /sdcard/

Download the file CWM 6.0.3.5

Got into Fastboot/Bootloader Mode on Nexus 4

Execute the command fastboot flash recovery recovery-clockwork-touch-6.0.3.5-mako.img

Choose RECOVERY from the Fastboot menu and enter Recovery Mode

In ClockworkMod recovery “flash zip from SD card”

Then selected “choose zip from sdcard”

Now I should see the copied file UPDATE-SuperSU-v1.43.zip but there was none, and I got the output `Can't mount /sdcard/

Then I tried to use Install zip from sideload

I sent the file with adb sideload UPDATE-SuperSU-v1.43.zip

I get the output:

```<code>Restarting adbd...
E:Can't mount /cache/recovery/last_install`
E:failed to open last_install: Invalid argument

Then I go back and choose reboot system now but when booting only the GOOGLE sign pops up and then the X (I was waiting for about an hour)

SOLVED
I did a full reset by downloading the original factory image from google

And then I followed the steps in this tutorial:

Google Drive App says folder is empty, even though it is not
I've recently started to use Google Drive on my devices (desktop, laptop, smartphone). It works great, but not on my phone. All folders were populated, but now some are suddenly empty (folder still there). I tried re-synchronising but nothing seems to help.

Any clues?


问:
Google Services consumes an excess of data since I moved
You know the part of android that checks your email, syncs your calendar and the such? Google Services has murdered my data cap, taking 605 MB of data in four days, two of which were spent with background data restricted and missed emails as a result.

Is there something wrong with my profile that Android sync keeps trying to fix but cannot? Is it something else? I noticed this started shortly after I moved from Wind in Italy to O2 in Germany.

according to google that means that the radio.img is corrup. I took it from the mirror of http://forum.xda-developers.com/showthread.php?t=687464 I have found an other radio.img which has the same version as the RUU from http://www.generalfiles.me/download/gs61d0834bh32i0/bravo.radio-5.11.05.27-signed.zip.html but that did make the desire shake three times when it was writing the radio and then hang.

XYZ X1 Change band from 900 to 850
I just bought the XYZ X1 Android phone with GSM: 900/1800MHz, WCDMA 2100 MHz
Unfortunately in my country are 850/1900MHz frequences.

Is it possible to change the band on this phone?

I've tried to change the band from terminal:

```<code>$ adb shell
shell@android:/ $ am start -n com.android.settings/.BandMode
</code>```

Starting: Intent { cmp=com.android.settings/.BandMode }

But only limited list was shown:

```<code>Automatic
EURO Band
JAPAN Band
AUS Band
AUS2 Band
</code>```

But there is no my band here, any idea how can I get it? Maybe base-band upgrade? thank you.
