Display slideshow on Android from files on PC
Ok, this has me frustrated. The good slideshow/gallery apps are already few and far between. But the wanted feature of having the Android show pictures that are stored on my PC, leaves the number of apps to, zero, it seems. I just can't find anything that works.

What I do is I run ushare on my Linux box. A couple of upnp browser apps confirm that they're seeing the ushare, and I can see the files being advertised. Then next, is any gallery app, that can actually access that available content and put on a slideshow.

My Android box is an Android TV box in the living hooked up to the large TV.

If I get fed up, I'll have to slap something together myself. I might concoct a network protocol myself, to give me good control over being able to only transfer what's need to show content...
Any thoughts?

Bluetooth audio connection flutters
I have a rooted phone and I recently updated to Android 5.1.1.

I have a bluetooth headset device, and since the upgrade, the connection has been distinctly degraded. The device pairs, connects, and plays sounds no problem. But, every 30 seconds or more, the sound flutters, as if the connection is weak. It makes listening to music basically pointless.

The difference before and after the upgrade is clear, so I'm sure it's the upgrade that did it.

The question is, is this fixable or adjustable? Or is it just a bad ROM and I need to find another?

问:
White screen while charging when phone is off
I'm using my phone (Lenovo A660) since more than two years.
Usually, I do not boot the phone to often (approximately once a month).
However, I recently realized when I turned of the phone, that the battery image is not shown when I charge my phone.
Instead the screen is completely white.
When I booted the phone again, the screen remained white all the time until I pressed 3 times the power button.
Then my standard launcher (Hola) gets started normally.
However, the screen remains white when I start into bootloader mode or into recovery mode.
Hence, I cannot select anything in a menu (e.g., to perform factory reset or to wipe cache etc...), as I have only a white screen.
May someone has already seen the same behavior and knows where I can search for a solution.
Many thanks in advance for all tips that get posted

Compact problem description:

White screen under the following circumstances:

Charging while phone is off

normal boot until I press 3 times the power button (has to be done after the phone vibrates shortly)

booting into recovery mode (either with the keys or with adb command)

booting into bootloader mode (either with the keys or with adb command)

Information about the phone:

Brand: Lenovo

List item

Model: A660

Android: 4.0.4 Rom: Stock ROM with build number A660_S025_121122

Recovery image: Stock image or CMW

Kernel version: 3.0.13 #1 Rooted: Yes with SuperSU v2.01 Fastboot: not supported

Approaches tried so far:

flashed recovery rom with CMW and with stock ROM. No improvement

Change /system/media/bootanimation.zip and /system/media/images/boot_logo. No improvement

added and removed again "debug.sf.nobootanimation=1" in the file /system/build.prop. Changes at least that at shutdown an animation is shown or not.

resetted the /system/fonts folder with a copy of the stock rom

physically cleaned display contacts according to https://www.youtube.com/watch?v=bt2kMKLNxVA

performed a complete dd image of /dev/block/mmcblk0 in order to be able to restore all partitons if something goes wrong

so far I spent approximately 2 days googling for related problems. However, may someone can provide a key word that I was missing in my search

What I could further provide, if necessary, are for example the logcat, output if that would help to debug the problem or to point me in the right direction.

Once again many thanks for any comment and suggestion.

Surprising problem to access Wifi Hotspot in Android 4.4 (Rooted)
I have uni proxy using NTLM authentication which I am sharing via hotspot created using this command

```<code>netsh wlan set hostednetwork mode=allow ssid="NAME" key="PASSWORD" keyUsage=persistent
netsh wlan start hostednetwork
</code>```

While my Android 4.4 (rooted) is connecting immediately, I'm unable to browse. I have tried,

giving the proxy in Wifi/proxy settings.

giving localhost:8080 and 3128 in Wifi/proxy settings.

giving WiFi IP in Wifi/proxy settings.

Also, LAN has auto-IP and auto-DNS. Hotspot has fixed IP and DNS is empty.

I thought it will take a minute, but one hour later, I'm still stuck.  What am I missing here ?


问:
Begin learning to root/reflash Android devices from Linux
I want to take an (older) Android device and replace the Android system.

I understand that I will need to a) get root access to it, and b) install a new system image (ROM&kernel). I also suspect that's a simplification.

My problem is that I'm having great difficulty knowing where to start.
I have found lots of disparate bits of information on small aspects of this, but much of it seems to start either with "magic" software on windows, or at some point arbitrarily far downstream, but I don't know how far, and I don't know how to get there. It probably doesn't help that I'm trying to learn this using an old "I don't care if I destroy this" phone (LG Optimus 670)

I am a long-time programmer and Linux user, so I'm comfortable with technical instructions provided they're accurate and don't use new terminology without explaining it, and I'm even happier with an explanation of how the parts of a system fit together, and the tools that interact with it, from which I might extrapolate what to do, or why something hasn't worked.

Unfortunately, while I go to the point that I can use adb to get to a shell on my device, it's not a root shell, and anything I try to do (beyond simple "ls" or "ps" anyway) is generally met with a permission problem.

Partly perhaps because I run Linux, not windows, I've totally failed to find a way to root my device (it's an old LG Optimus 670 with a ZDJ "baseband"--what's that, btw, I thought baseband was a term referring to a way of using a medium to carry a single signal, as distinct from broadband, meaning you can encode multiple signals onto it! Perhaps this relates to the software controlling this behavior?)

I've also read that the ZDJ must be downgraded to ZDM before rooting, but I don't know where to begin doing that either.

So, can anyone suggest a good resource that might explain the fundamental structure of an Android system, so I can begin to get a better grip on it? And, can anyone tell me if there are resources that will help me hack this system using Linux as my host, rather than windows? (Or, if I just have to have windows, I suppose that's worth knowing, I could probably bring up a virtual machine if I must!)

Many thanks!

Redo one-time setup?
Due to a flaw in the way that Android does decryption*, I setup my devices by skipping through all the first boot setup stuff provided by CyanogenMod and Android.

I then immediately go into the settings and encrypt the device. This makes it so that there's no accounts ever stored on the device in plain-text.

Is there a way, after I encrypt the device, to go through the one-time initialization again? Are there applications for which I can simply wipe the data which will trigger the next boot to run through first time setup again?

How do I stop Play Store connecting to a specific WiFi SSID?
The WiFi network at an office I frequently visit has firewalled the Play Store, or some port that the Play Store uses. In any case, it is impossible to connect to the Play Store over that network, and this has been confirmed with IT. The error message I get if I try, is "background data must be enabled" -- which it is.

This would be much less irritating if the error message weren't persistent. That's to say that if I once try to update anything while in that office, the error message comes up -- and I then can't connect to the Play Store at all from anywhere until I scrub the cache and data from the app, even though background data most certainly is enabled. Obviously this is a bug in the Play Store software: a flag is getting set and then not tested again and unset. But my question is how do I work around it.

Is there a way to tell the Play Store -- and only the Play Store, not other apps -- not to connect to a specific WiFi network?

How to install Android Package manually (without Google Play, adb install, or "Install" click)

Backstory

Before we get into question, I will explain what happened in my android.

Earlier, I got random bug in my Android that causing my OS got "Half-restored factory settings."

By the means Half-restored, some of my basic configurations are reverted to default (wallpaper, Settings, LINE, Facebook, Browsers, even Google Accounts) while some apps are not reverted. I wonder why.

Then I found that all apps that I installed on SDCard are considered uninstalled by my Android, though the ASEC files are still there.

And when I looked up into /data/data/, all data are still there as well.

Then, I tried to manually mount .asec files (tutorial here) and successfully mount the .asec into /mnt/asec//. APK, data, library and configs are there as well, too.

But unfortunately, even after I mounted the asec manually, it still considered not installed yet by OS.

Question

So those events and conditions raise me questions:

Is there any command, or configuration/text that I can edit to make those mounted ASEC apps considered installed?

How to reinstall those apps without losing orphaned data? (because if I reinstall the app, the app will go to /data/app partition and the /data/data will be overwritten)

Thanks for reading, I'll look forward for the answer.

Additional Info

For additional info, I use ZTE N986 on 4.2.1 Android Jellybean OS (official stockrom), rooted (obviously) + Xposed.

This accident occurs whenever the android has battery collapsed (0% and turned off by itself), though it's not always (even rarely). It's just I experienced this bug numerous times and this always happens when I have 0% battery.

Options for Stolen Phone
With an iPhone, you tie your phone to an iCloud account - it happens at the bootloader level. If your phone gets stolen, the thief can't do anything until the previous owner releases the phone from his/her iCloud account.

I have a co-worker who had his iPhone stolen. "Later" he got contacted by the new owner who wanted to use the phone. Obviously, co worker wouldn't do this - that's what you get for buying a stolen phone. The new owner can't do anything with the phone except send it back or break it (he took option two, unfortunately).

I see plenty of options that allow you to track, remote wipe, lock, activate alarm, etc... You can encrypt the device and/or sd...

But what is stopping the next person from flashing or factory resetting the phone, formatting the encrypted SD and using both of those anyways?

So my question is...Are there any standard options that will stop the phone from being reformatted or is that something that's up to the phone manufacturer? I don't want to remotely brick my phone if it gets stolen - I want to stop it from being used by anyone but me - full stop.

Small plastic ring obstructing the front facing camera on Samsung Galaxy s5
there.
I am hoping to take apart a Samsung Galaxy s5.
The trouble is that there is small black ring that has displaced and it is partially covering the front facing camera.
I am not completely sure what caused this.

If it were my phone I would not be too worried about taking it apart.
I want to make sure I understand what I need to do.

Here is a video I found that disassembles the phone. I believe that up until about 2:40 in that video is all I really need to do to get access to the front-facing camera and the displaced ring.
Hopefully that will provide enough space to move the ring back in to place.

What I am looking for is an answer to the following question.
In order to remove the screen I need to heat the phone up so as to loosen the glue.

When I go to put the screen back on, will re-heating the phone be sufficient to make the original glue set again? Or will I need to buy some replacement glue in order for the screen to sit securely again?

Perhaps someone out there has some experience with this. Cheers!

Android Chrome HTML5 playhead glitches every minute or so?
Whenever I play either an embedded HTML5 video or just watch it from the direct link on my Android device, the video plays for about 1 minute then stops as if it's trying to buffer. I tap the screen to bring up the GUI (so I can drag the playhead back a little) but nothing happens for a few seconds. Then it comes up but all the buffered video has disappeared and the time that the playhead is at will be about a few seconds ahead in time from when you pressed the play button initially. Sometimes it flicks between seconds. I then have to guess how far through my video I am and reposition the playhead for it to continue playing until I have to do it again. It's extremely tedious and annoying. Another thing is that when the video stops and the playhead glitches, sometimes the sound will keep playing as if the video had just been buffering but the video stays frozen.

Example: I start playing from 0:00 and watch til about 1:30 (I don't see that I am at 1:30). The video freezes and I look at the playhead which flickers between 0:05 and 0:06. I reposition the play head at about where I think I got up to and the video plays as normal for about another minute until it happens again.

I am running Cyanogen 12S on a OnePlus One.

Motorola Moto G 2014 (lollipop 5.0.2): `pm set-install-location 2' does not work
I have rooted my Motorola Moto G 2014 (lollipop 5.0.2), using TWRP to load SuperSU.

I wanted to have all applications that could store some of their data on an external SD to do so automatically, when they are installed or updated (i.e. for the MOVE TO SD action to be automated).

After reading several guides, and answers on to questions on this forum, I thought this could be achieved by executing the following commands:

```<code>su
pm set-install-location 2
</code>```

However, the behaviour after the above setting change was undesirable.

When apps that I knew had the ability to MOVE TO SD were installed or updated, they were still being stored on the device's memory, not on the external SD card.

Also, entries appeared for more apps than are usually displayed in the ON SD CARD tab, within Apps settings.

If the MOVE TO SD action was performed on these new entries, the device's behaviour became erratic. App links disappeared from the launcher, and Unfortunately, app_name has stopped. messages were encountered.

I just want for applications that can be moved partially to the SD card to do so automatically.

Android phones that don't require a battery to run properly
My Android phone apparently requires a battery in order to function.  If I take out the battery before boot, it shows an empty battery with a question mark on it and refuses to boot no matter how I press the power button.  If I pull the battery during the boot process it boots up just fine, but as soon as it finishes booting I get a dialog box telling me the battery isn't present and it automatically starts the shutdown process.  If I pull the battery after boot is completely finished, it instantly reboots as if I pressed shift+alt+del on my slide-out keyboard.

Is this standard Android behavior, or is this something unique to my phone?  If I ever replace my phone in the future I have a list of required features, and being able to run without a battery is one of them.  So, I need to know if this is going to restrict my options.

Can't make or receive voice calls anymore
I have a Moto G 2013 (XT1033) with latest Lollipop.

Suddenly I'm unable to make any voice calls. I open the dialer, input the number, press dial and... nothing happens.

Either I'm thrown back to the dialer or I get a "call ended" message instantly after pressing dial.

I also can't receive voice calls, either: they go straight to voicemail. SMS are OK, then I know it's not the SIM card problem.

By adb shell and dmesg I saw those error messages which make it look like the internal memory is corrupted.

What to do?

Nexus 4 red light of death. Unable to fix it (tried two possible solutions)
Using a 3-year Nexus 4, I started yesterday to suffer the red light of death issue.

Firtsly, I open the unit, disconected and conected the battery, following the directions of:

It did not work, so I tried to power off the device through the bootloader menu:

Is there any way to control my android phone remotely from another android?
I have an Android Galaxy S4 Mini (SGH-I257) that is not rooted and running stock software Android 4.4.2 and an Samsung Galaxy Admire (SGH-R830C) rooted running stock Android 4.1.2. Both devices are fully updated.

I am trying to use my S4 Mini to control my Admire, is this possible? I have tried using TeamViewer and but that does not seem to be working. I tried droid VNC which worked but the interface was very clunky and it seemed to be made for computers.

I basically want to open an app on my Mini and have my Admire appear, like remote desktop connection. I don't need sound, but I would like to be able to click the home button remotely and be able to swipe the lock screen to unlock.

VNC works, but it will not work outside my home network which defeats the purpose. Could I host this via my modem I have? I have an At&T Uverse Motorola NVG589 modem running software version 9.1.0h12d34.

How can you sync multiple outlook calendars including delegated calendars
So I need to sync a user's calendar to their Galaxy S6's Calendar/Planner they are on the latest OS (Lollipop 5.1), I can't seem to find a way that will allow me to sync their outlook calendar and their boss's calendar to which they have full delegate access.

Is anyone aware of any solution to this? This is in a corporate environment so if the solution is long-winded or very complicated it won't be viable as the user's setup their emails on their phones.

The user can see their calendar fine it's just the delegated calendar that I can't seem to find/sync.

I've tried downloading the Outlook App, multiple calendar apps etc.

Cyanogenmod works with ext4 filesystems on sdcard?
Basic reference: How can I mount an ext4-formatted SD card with correct permissions (with root)?

I succeeded to make a partition with ext4 filesystem on the SD card, and I mounted successfully following the reference above. However, I still found that the permission issue is there if I want to copy some files from Linux systems to SD card.

I found that the gid of media_rw is 1023, therefore I created a group on Linux system as such:

```<code># groupadd -g 1023 media_rw
# gpasswd -a USER media_rw
</code>```

After that, I can modify data on sdcard. However, if I create some new files, the owner & group will be that of USER and the mode is 755 or 644, not 775 or 664. Everytime I need to run a root shell and

```<code>$ find . -type f -exec chmod 664 {} \;
# chown -R 1023:media_rw .
</code>```

It's very annoying. I wonder what's the correct way to exchange data for cyanogenmod.

Any help? Thanks!

EDIT:
I found a method to set permissions except the owner:

```<code>$ rsync -r -p --chmod=D775,F664 -g --chown=:media_rw SOURCE DEST
</code>```

Automatically download Dropbox Favorites to the external SD card
When a file is marked as favorite on the Dropbox app it is downloaded to the phone's internal memory for offline viewing. Dropbox also "attempts to keep the file as up-to-date as possible and gives you the option to update the file manually". [source]

My question is - Is there a way to have Dropbox download the favorite files to an external SD card? I am aware of the "export" option, which allows you to save files to the external SD card, but it is cumbersome and does not keep the downloaded files up to date.

Any ideas?

Boot looping Galaxy Ace GT-S5830i
I sent my broken phone to repairs, and they lost it. So I'm awaiting a replacement and in the meantime, I have a bog-standard non-smart phone. My mum very kindly said I could borrow her Samsung Galaxy Ace while I await the new phone. I don't know if the change in SIM cards has triggered boot looping issue.

So, I'm busy using the phone, deleting data from Facebook/whatsapp periodically because the storage on the Ace is low, then suddenly it starts boot looping. Not sure if I inadvertently cleared data from somewhere I shouldn't.

I have tried clearing the partition cache and factory restoring with no luck.

I followed some instructions to download Odin (not the latest version but 1.7 or something such), set it up as instructed in the particular video I was watching, but when I connected the phone to the computer it didn't connect to the program.

I tried to download a newer version of Odin, but got a virus on my computer.

GT-N5100: Random apps crashing suddenly
So, I got this problem with my Android GT-N5100 (running Android 4.4.2). It keeps crashing apps suddenly and randomly. I flashed it with Samsung's official firmware and since then it keeps like that. I know that if I factory reset it, it's gonna be happening the same way.

I was thinking about flashing Cyanogenmod but my device is currently unsupported. That is.. There are only nightly builds available for it at this moment, and it takes too many hacks to do so, then I'm not risking it. I thought also that it could be a memory overflow problem... Maybe.. But every time I open the window manager it seems to have plenty of memory left. I use to kill apps to avoid that, but no matter what... You got it.

Would someone PLEASE link me to a stable firmware free of bugs like that or tell me what the hell is going on and how can I fix this problem??

I'm tired of it... Believe me.

Moto G 2014 XT1068 is bricked. Keeps looping and won't boot. What to do?
Ok so here's a couple things about my phone:
Its bootloader is unlocked, it is rooted, and it has a custom recovery (TWRP).

The problem is, my phone got stuck in the "WARNING, BOOTLOADER IS UNLOCKED" screen. I was using it normally, when Chrome froze then the phone turned off. It won't do anything else, it just keeps looping: it shows the warning, then the screen goes blank. When I try going into recovery mode, it just shows the TEAMWIN splash screen and won't do anything else, even though I tried every possible button combination I could find on the internet (volume up, down, power, 15 secs, 1 minute, etc).

It gets worse. When I'm on fastboot mode, I can plug the phone on my PC via USB but it won't be recognized. It appears on the device manager as "fastboot titan s" but the phone itself just keeps saying "Connect USB data cable" as if it's not connected.

It won't be recognized by RDSLite nor mfastboot applications, even though it shows up on device manager.

What can I do?

问:
Why does the Kernel and Android System/Android OS drain my battery?
3 hours since unplugging my phone, and at light usage it's at 61%. It is the kind of problem I've had with my previous phone, and I have with my current phone, often starting a few months in and intermittently.

GSam indicates that app usage is 88% of it, with Kernel (Android OS) being 38% and Android System being 21%.

I know it is probable that "some apps" are using some OS functions and that would be the culprit.

Seeing it's a problem that hasn't been solved in more than a year, (even in Lollipop) I'm submitting it here so there's a definitive place to show the solution when it's found, instead of checking endless forum threads on XDA. (Hence note the answer must offer some kind of solution instead of "it's impossible")

I am not willing to take stabs in the dark such as disabling Google Now or Location tracking without a definitive proof. I have Wakelock Detector and it does not show anything unusual.

How do I definitely find out which app is responsible for the drain?

Will an LG G3 Beat work on Verizon in the US?
I asked on Travel a week ago about getting a temporary phone for a trip to Europe but my requirements have changed. Now I need a phone that works in Europe and the USA.

I got to looking at the LG G3 Beat, which is listed as a world phone, using the wireless bands GSM 850/900/1800/1900 MHz. But while I was shopping, I noticed that many retailers do not include Verizon on the list of carriers that the phone will work with, even though Verizon has 850 and 1900 MHz GSM spectrum. Some even explicitly say that the phone will not work with Verizon, because -- according to them -- Verizon is a CDMA network.

My attempt at researching has turned up a lot of posts from 4-8 years ago saying that Verizon was, at the time, in the process of switching from CDMA to GSM. I didn't find any definitive "the transition is complete" announcement, but the best I can tell, it seemed like GSM was fully rolled out as of 2014 1, with CDMA still being kept around purely for legacy support until 2021. (Please correct me if I'm wrong about any of this.)

Are the retailers mistaken about the phone not working with Verizon, or am I not understanding something about how networks work, or is the phone incompatible for a different reason?

Can't install Cyanogenmod on Galaxy S3
I can't seem to get Cyanogenmod installed onto my Galaxy S3. I've followed the steps on their website, and I've gotten the custom recovery installed just fine. But actually installing the Cyanogenmod Nightly isn't working, both for the sideload and push and install.

I am admittedly new to Cyanogenmod so I'm not sure what's going on with it, or if I'm getting a simple step wrong.

When I try installing from zip in the recovery nothing actually happens and nothing changes when I reboot the phone.

Then when I try to install it via push and install, I use the command:

```<code>adb push cm-11-20150426-NIGHTLY-d2lte.zip /sdcard/0/
</code>```

It tells me:

```<code>3426 KB/s (227230178 bytes in 64.765s)
</code>```

And again when I try booting the phone up nothing has changed.

I got something different when I took the /0/ out of the code
So I put in:

```<code>adb push cm-11-20150426-NIGHTLY-d2lte.zip /sdcard/
</code>```

And I get:

```<code>* daemon not running. starting it now on port 5037 *
* daemon start successfully *

</code>```

Nexus 7 (2013) Boot Failure
I have a Nexus 7 (2013), 32GB, WiFi-only, that won't boot.  I had been using it daily, until it failed.

I had left it running, but on the 1st day after the warranty expired it would not wake up when I pressed the power button.  In fact, there were no signs of life.

Thinking it had just hung up on something, I attempted to force it to power-down by holding the power button for 15 seconds... can't tell if that did anything or not.  Again held the power button in for a few seconds and "Google" appeared, like it was starting up.  It did not change state for the next several hours, so I repeated the process a few times.

Eventually, I checked online and found references to Power+Vol-Down, which I tried and it brought me to the bootloader screen.  I have attempted all of the options there, but they all bring me to the same place... "Google".

I contacted ASUS support and they had me try a few things, including "Recovery Mode", which also failed.  The actions directed by "support" took me to an Android laying down, cover open, with a red triangle on it.  The end result of that conversation is that I should send it to Puerto Rico for repair at a cost of $240 (plus shipping), which is more than I paid for it.  He said they would replace a system board and return it to me.

In further research, I found the Skipsoft Toolkit (v3.1.0) (02-Jul-2015).  I installed it on Windows 7 and successfully attached the Nexus to it via USB and it recognized the device in fastboot mode, but not in ADB mode.

I've tried the function to back up the device, but it just hangs there, even after a couple days.

I've tried the function to unlock the device and I get a screen on the device asking for permission to proceed, but then it hangs.

I'm looking for advice or direction to move forward... or is my device really "done"?

Contents of the bootloader screen:
FASTBOOT MODE,
PRODUCT NAME - flo,
VARIANT - flo 32G,
HW VERSION - rev_e,
BOOTLOADER VERSION - FLO-04.05,
CARRIER INFO - None,
SERIAL NUMBER - 07b04e4b,

Android Music Player - Does the default "Music Player" program store the timestamp of when a song was last played?
I have a question about the recently played items in the Android (specifically v4.2.2) media library.

Does the default "Music Player" program store the timestamp of when a song was last played? Or does it simply increment a play counter or even just append the song's index to a table? Any explanatory information about the two dynamic playlists: "recently played" and "most played" will be most appreciated.

For background: I am trying to determine the last time an MP3 was played on an Android phone (Samsung Beam2 Android v4.2.2) and any help is very much appreciated. I have rooted the phone and pulled what I think are the media SQL lite databases from here:

```<code>/data/data/com.android.providers.media/databases/internal.db
/data/data/com.android.providers.media/databases/external.db
</code>```

Browsing these with an SQL Lite browser I can see all the MP3 files and the "files" table holds columns for "recently_played" and "most_played". However, these columns are empty, so I may have pulled the wrong database. If I found the correct database, what kind of values can I expect to find here? Flags? Indices? Or timestamps?

Any help is very much appreciated, I am an experienced developer but have little experience with Android.

How to store Dropbox files locally on my mobile device?
We all know how Dropbox works on a regular workstation. It stores the files on the disk and whenever the file is modified (or created), the software synchronizes the entire folder with the last committed folder (updating the previous files and adding the newly created files).

However this is not the case with Dropbox application for mobile devices (at least for android). The official app gives us just the interface of the folder stored on the cloud (Dropbox server). To access the files, they have to be downloaded. Changes are detected, if made; and then the files are updated.

My problem is I have to access my Dropbox files too frequently but I don't have a decent internet connection all the time. I am barely using 20-25MB of my dropbox space. The files I need to access frequently are merely some txt files of 100-200kB. I want to access them without an internet connection but whenever I update them and afterwards whenever my device finds a decent internet connectivity the files should be updated on the server.

Is there a third party application for it? Or is there any existing Dropbox feature for it, I am not aware of?

Recovering deleted call logs in Android 5.1.1 - to root or not to root?
I accidentally deleted my call logs/histories and badly need them now. I would like to recover the call logs and tried few softwares. Most of them were not successful in recovering the deleted call logs. Some are asking permission for rooting or superuser access.

Is rooting a right thing to do for recovering my call logs? Will it affect my android phone in any unexpected ways?

Are there any other ways or softwares where I could recover my deleted call logs?

Any help would be appreciated.

Android Device manager
I just recently know about Android Device Manager. So i tested it on my own phone (moto g2). Then i thought, lets have some fun. So, i ask for gmail account and password from my friend. After getting that, i went to google in her account and then to Android Device Manager. But her phone (Mi4i) had just two option into it "ring  | enable lock and erase". So i just click on option "enable lock and erase" hoping that before doing anything it will ask yes or no. But instead it said done or something. Just tell how can i undo it and what exactly happened when i clicked that button?? i would really appreciate.  </p>

Galaxy S3 running CM11 - SystemUpdateService keeps getting disabled
SystemUpdateService is currently destroying my battery (phone awake 98% of the time) because it's not running (The update services acquires a wakelock to check for updates, but since SystemUpdateService is disabled, it never finishes the check and the device stays awake.)

The service is under both of the following apps:

Google Play Services

Google Play Services Framework

If I use the DisableService app I can kick them back into action again... but whenever I restart my phone, they're disabled again. Also, sometimes they randomly switch off again at random.

Any idea how to keep these services running please?

Many thanks

Does Something wrong with the SD card in use refer to an issue with the android software or its an issue realted with the Sd card itself
I recently updated the OS from Jelly bean to Kitkat Android v4.4 and after this update I am not able to download any file from the browser. Every time I try it gives this pop up and the download fails.

I tried even using the Internal memory but still the issue persists.

Screenshot 1 - Something wrong with the SD card in use.Please check if your SD card is available for downloading

Later when I select the default path then it gives me the below popup.This pop's up  even when I am setting the internal/Primary storage as default

Controlling Android device from Android phone
Kind of related to this question.

I want to control my android tablet (galaxy A 9.7 SM-T550, Android 5.0.2) with my Nexus 5 (Android 5.1.1) . Both are rooted and I want to be able to control the whole screen of the tablet using WiFi (wifi hotspot from Nexus 5, to use in the car). I have tried Webkey, but the service wont start. Remote Tablet is able to cast the screen, but no input events is registered.

App nationality in Play Store while updating from different location

Why are ringtone-songs I buy from Google Play impossible to make into ringtones?
This is not a duplicate question --- at least not a duplicate of many questions that the search-engine gave me that seem similar up-front -- but as soon as I read them, I realized that they do not even address my question.

My situation is fairly simple --- I purchased a ringtone-song on Google Play -- and was hoping to set it as my ringtone.

When I went to settings and tried to select a ringtone -- the one I had bought and downloaded wasn't available. But that's not when my frustration hit the roof.

Next, I hit the '+' sign in the upper left-hand corner -- and it asked me what app I wanted to use. I tried this three times - one for each of the three apps they offered to carry out this option with.

Here's what really irritated me ---- each of those apps (including Google Play) I got the same-old same-old pre-installed songs available ---- no way at all to got to the track that I paid good money for!!!

What am I to do? Is there a bloody way that the song I paid for in order to set as a ringtone can possibly be set as my ringtone?

Apps have become lost on main phone memory
Many of apps have disappeared from the main screens. On investigation I find they were all on the phone memory - the ones still working are all on the SD card. In app manager they are in the list of downloaded apps but are greyed out, and most of them start with an odd name such as com.android.... or just com... eg com.prey which I don't recognise.
Even more odd, the browser has disappeared too. That' was pre-installed and I can't see anything relating to it in that greyed list. Similarly play store has gone.

How to check if flashlight is activated?
I've got a brandnew OnePlus One with Cyanogenmod 12 on it, and the device is rooted.

I like the offscreen gestures very much. But sometimes they are triggered accidentally. This is very costy when the flashlight is turning on and you don't get it.

So my thought was, to write a task with Tasker, which let the phone vibrate, when the flashlight has been enabled.

But unfortunately I have no clue how. I looked for a solution in the web, but I didn't find anything. So maybe you have an idea how I could achieve this. Thanks in advance.

OTA upgrade after flashing with stock Lollipop ROM
I flashed my HTC One M8 with a stock Lollipop ROM from here.

And now there's an OTA upgrade available called Android L-MR1 that I cannot install because when the phone reboots it boots into TeamWin recovery mode and requires a password.

The password is most likely because the phone is encrypted, but typing in my lock screen code is invalid.

I ask TeamWin to reboot into system and the story begins from square 1 with the upgrade being ready to install.

So how do I proceed to get this upgrade installed? Should I remove TeamWin recovery?


问:
Samsung keyboard security bug - was patch released?
Last month, a security flaw affecting the bundled (and unremovable) keyboard app used in many Samsung devices (S4, S5, S6) was announced:

New exploit turns Samsung Galaxy phones into remote bugging devices

Samsung Mobiles Vulnerable To Keyboard Cracking Attack

CVE-2015-4640 - SwiftKey language-pack update vulnerability

Samsung promised that a fix would roll out within a few days of June 18th

However,  I haven't seen any announcements that the fix was actually pushed -- how do I confirm that my device received the update?

Samsung initially reported that they provided a patch to the cell phone carriers, but since carriers are known to be slow to patch phones, especially older models, as far as I know, that patch has not made it out to phones, and it's not clear that it ever well. So Samsung said that they'd push it out directly to users.

HTC Desire 816 CM12 Nightly SMS not working
I just flashed and updated everything on my HTC Desire 816 and everything went just fine. But I followed this APN fix and it doesn't seem to have worked as it should, and I haven't found anything on the thread.
It says I have LTE, it says my network is Virgin Mobile and that I'm in service on the Status page but I can't send any texts and when I scroll the status bar down it says "No Service".

I've never had to mess with APN settings before so I don't know what to do about any of this. The only thing I can do is connect to the internet without WiFi.

Sorry if this is a bit rambling. Like I said I've never had to mess with any APN settings before so I don't know what info is needed.

All browsers are failing to open any web pages
I have a Galaxy S5 with Android 5.1.1. My phone is rooted, and has been working fine since I updated about a month ago. Within the last few days, I have been having this issue, and I don't know what change might have brought it about.

My preferred browser is Firefox, but I also have the default browser and Chrome installed. Regardless of which of them I use, when I open them, they just give me a white screen. Eventually I just get the message that says I can make the app stop, or wait for a response.

All other internet connecting apps work fine. Twitter, Instagram, Facebook messenger... it is strictly only browsers that are not working.

What is strange to me is that it is more than one browser that is failing. If just Firefox, or just Chrome, was failing, then I would assume the apps themselves were broken. But it's all three browsers failing the exact same way.

This happens whether I'm on wifi or mobile service. I've tried restarting the phone, and I've tried uninstalling and reinstalling the apps, as well as clearing cache and data.

Is there some system resource common to all of them? Is there some plausible explanation for why all browsers would fail? And, of course, if there's a solution that can get them all working again, that would be great.

"Incompatible with other applications(s) using the same shared user ID” while installing Google Play service?
I know similar question is floating on the same site, but no solution works for me.

I have been using Karbonn A26 Smart phone for the last two years, and I was not able to install run YouTube and Google+ since 2 years. Its hardware is quite ok. It runs Android 4.1.1.

Let me be clear what I am doing:

When I install and open YouTube, it says YouTube cannot work without Google Play Services. When I click on Get Play Services, it gives me error: "Incompatible with other applications(s) using the same shared user ID".

So I factory reset the phone. Then I try it out, same. I can download and install YouTube, but when open it, it keeps saying same "Cannot play without Play Services".

Same thing happens when I install and run Google+.

Installing YouTube on clean OS itself does not work.

I just switched to my first Android phone (been an iPhone user until now), running Lollipop 5.0 on a Sony Xperia Z3 Compact, and I am having a strange issue.

If I receive messages on Facebook Messenger or emails on Outlook.com and view them on my PC, while my phone is not connected to the internet, these emails and messages should be marked as "read".  When I next connect my phone to the internet (even if it is hours after I would have read these emails and Facebook messages), I get notifications of the emails on my phone, and a notification for each message in the Facebook Messenger conversation.  The phone keeps sending notifications for literally each email and each message which would have been received and seen on the PC.

Does anyone know what is causing this? I did not have this issue on my iPhone and it is really annoying me.

Nexus 5 WiFi problems
I believe it's somewhat well-known that the Nexus 5 has had more than a few hiccups with certain wifi networks.  However, I'm not sure that the main reasons for wifi connectivity issues is as well known (as it should be).  It seems that every other time I update the OS (Cyanogenmod 12/ 5.1.1) I find myself frantically searching for a solution to some wifi-related problem on the Nexus 5.

This week, after upgrading the OS I was confronted by the same issue once again--or at least I thought, as I hadn't exactly documented every previous case.  My search for a solution led me to the numerous troubleshooting procedures and potential causes of the problem:

IPv6 automatically connecting

Nex5 failed to delete AP properly

outdated radio/modem image

After gaining access to adb shell and executing logcat network:V I noticed that the network interface Associated with the Access Point and

```<code> wlan0: CTRL-EVENT-EAP-SUCCESS EAP authentication completed successfully (based on lower layer success)
</code>```

Then, immediately after that something failed, even though I thought the connection was successfully made!

```<code>wlan0: WPA: Failed to configure IGTK to the driver
I/wpa_supplicant( 5891): wlan0: RSN: Failed to configure IGTK
</code>```

It turns out that IGTK meant something with Protected Management Frames (802.11w).  I should note that the router's configuration had the option set as "Capable", as opposed to "Required".  After disabling that feature on my router the connection succeeded.  Now, given that fact that ALL of my other devices had no problems with this, why did the Nexus 5 persistently fail to attain a connection to the Network with Protected Management Frames enabled? Is there a security risk with this issue, especially if the Network Admin compromises it for the sake of one device's flaw? How would one mitigate this problem on the android side?

Is multi encryption a good way to wipe all traces of personal data before selling the phone?
I am going to sell my phone.

It's a Samsung Galaxy S4 i9505 from Germany running Android 5.0.1 "Lollipop". What I have done so far is to encrypt, reset, run camera until memory was full to override empty memory with random data and then reset again. But I think I have forgot to disable "fast encryption" which encrypts only the used memory (I have manually deleted some files before ). I am not sure if I have disabled it or not.

Is it a good idea to perform the encryption again (with "full encryption"), or is multiple encryption a bad idea in case of security?

Samsung Galaxy S4 - no adb devices
I wanted to install a custom ROM on my old Galaxy S4 I9500. I installed CWM recovery at first with Odin, and it worked really well.

Thereafter, I tried side-loading or pushing the custom ROM using ADB, but it could not find the device.

I tried to install Samsung drivers and reinstalling them but it didn't work.

Any solution to detect the device?

Songs appearing twice in many mp3 apps, though there is only one file per song
I have reordered my mp3 collection with the excellent easyTag tool.

Now on my LG-430 and on my Xperia Z1 compact, in the native music players of the smartphones as well as in the external apps Equalizer+ and Poweramp, in many albums every song appears twice.

An example is Mick Jagger's "Goddess In The Doorway". I have checked with a file explorer that there is really only one mp3 file for every song. I have checked with easyTag that all tags are set correctly.

Another strange tagging error happens with the Stones' famous "Exile On Main Street" album (OK, I admit, I am a Stones junkie, forgive me). Here the very first song of this early 70ies double LP, "Rocks Off", is put into an album called "Exile On Main St. CD1". All other songs of the double LP are put into an album with exactly the same name.

What am I doing wrong or what is wrong with the mp3 collection apps?

Greetings from Germany!

Prevent phone unlock by secondary google account

What I have done:

I have added multiple google accounts to my device.
Also did set screen pattern lock and pin as fallback.
Tried to give wrong pattern and selected unlocking by google account, I could use any active google account and it will remove both pattern and pin.

How I want it to behave:

I am lookin for some way to restrict unlocking/pin reset to individual selected google account while retaining keep/drive/mail/contacts/calendar etc, synchronization, is that even possible?

Most recent root and flash rom for Verizon Note 3
I know this is a super specific question, but I am trying to root and then flash cyanogenmod onto my Verizon Note 3. It seems like security features change constantly for Samsung phones and I have not been able to keep up. Can someone point me in a direction (maybe to a tutorial) that is up to date for flashing roms and rooting.

Ive looked but one says one thing while the other says the opposite.

No Service Error
I am having trouble with my device (galaxy s4 ,model number SPH-L710, running android 4.4.2). In particular I cannot send or receive text messages or send or receive calls. I noticed that if I dial in the code *#0011# to go to Service Mode, the screen displays the message No Service at the top. Could this be related to the previous issue? And how might I fix this?

My apologies if this is an inappropriate question for this stack exchange.

How does encrypting a bootloader prevent it from being unlocked
As I'm waiting patiently (sigh) for the at&t note 4 root, I have been trying to understand the process of rooting.

This website does a good job of describing what a locked/unlocked bootloader is, but it doesn't explain why encrypting a bootloader makes it impossible to directly unlock it like an unencrypted one.  It mentions that some bootloaders are not "unlockable" but it doesn't go into detail.  So what about encrypting a bootloader makes it difficult to unlock, and what does encrypting it make it difficult to root (if it does)

Disable “Allow USB debugging?” message
I have a tablet with a cracked screen, but I can use it with usb mouse connected via OTG. One problem is that I cannot connect it in debug mode because whenever I connect my tablet to PC, the message "Allow USB debugging?" appears. So it's a problem: while tablet connected to PC message appears, but in order to accept it I need my mouse connected, but USB port is busy. I have no root, but I have recovery. So is there a way to deal with this message? I know that I can use bluetooth mouse, but I wont have it as soon as I want to debug my apps.</p>

Calendar adds one hour to whatever time I set
When I create a new event and set the time to 12:00, it turns into 13:00 right before my eyes, on the new event creation screen. How do I fix this madness?

I've googled this issue for a while and I don't think it's just the daylight saving time thing everyone else is having. My time zone is Moscow and we recently stopped saving time, so there's no option to select between +3 and +4 time zones.

My device is HTC 626g+ and I'm having this problem with the default calendar app.

Multiple Outlook.com calendars to Lollipop stock calendar
My phone went ballistic yesterday and auto-erased everything and after that I upgraded from 4.4.2. to 5.0.

Now that I should be a happy Lollipop user I've got a huge problem with Outlook.com calendars.

I've got total of five calendars set up to my @outlook.com -account. All those calenders synced without a problem with 4.4.2.

Case 1)
Now with 5.0 when I add new Exchange-account (meaning my Outlook.com) events from all the calendars are synced into ONE CALENDAR - not to five separate ones. Also I can only create events to the "Main" calendar.

Case 2)
If I install the official Outlook.com app - all the calendars are visible in the Outlook.com app, but are not synced to the stock calendar.

It's like pre 4.4 again! This issue was fixed for 4.4.2 only and now it's gone again...

Is there any way to get all the Outlook.com calendars working with the stock calendar?!

My corporate Exchange calendar is visible via stock calendar and that is why I want to see our personal Outlook.com calendars in the same calendar... OR if yu can point me an app that does what I want I'd be thrilled!


问:
creating mount point in root mode
When trying to expand tablet memory (from 500 Mb to 1G) I made a mistake when I was applying Gparted. I reset my device to the fabrication settings and now I can't mount sd card (no the real sd card), so I can't transfer files between device and computer. Also, the date of some folders are too old(1969!) and some permission are weird:

How can I create a mount point? (I think this is the central problem to connect my device with PC).
I read somewhere that I must be root to change stuff in the tablet system, so I entered as root into the tablet with it:

```<code>adb shell
</code>```

and I was prompted to

```<code>root@android:/ #
</code>```

(now, am I in root mode, right?) and I can explore all the folders of my device. From this point, how can I create a mount point? what commands are required?. My tablet data are: SpreadwinPuppis model, Androdid 4.0.4, Core version 3.0.8+ spreadwin 2.4.10 (S101_SS_A), help :-/
