How can I get old Android updates again after a hard reset?
I have an AT&T HTC that was running Marshmallow 6.0.1 and Sense 7. That's the last update my phone will ever get since it's an older model. I factory reset it to wipe it clean, which returned the software to Lollipop 5.0.2 and Sense 6. I've checked for updates in the settings and it tells me it's up to date even though it's not. Do I just need to wait a few days to get the update notifications? Or do I have to take it to AT&T and have them update it? Or do I have to flash marshmallow myself?

Does no mention of GPS (on selling site) mean there is no GPS?
I'm looking at the AT&T LG Phoenix 2. It does not mention GPS on either Best Buy nor AT&T, and only mentions a cryptic "GPS Service for location accuracy" on LG's site. (Though phonearena.com does mention GPS.)

Can it be that a phone with a GPS antenna would not be mentioned as having one (why?), or is this a sign that it actually doesn't?

Gmail app only partially syncing
I've just bought a Lenovo B phone with Android.

I've added my Gmail account and have enabled the Gmail sync in the phone's settings. It has downloaded all my emails, however it won't properly sync which emails have been read or not.

I read a couple emails on my MacBook using Thunderbird... however on my new phone, the Gmail app says that these emails are unread.

I know it's not a problem with Thunderbird, because I also have a Samsung A3... and my mail on that phone is all up-to-date in terms of what emails are read / unread.

Also the sync settings in my Lenovo say that it has sync'd within the last few minutes (I originally set it up about 30 mins) and this was way after I read those couple emails. So it should have updated them by now.

Does anyone know what might be wrong?

Edit:

I tried sending myself an email using Thunderbird... it showed up on my phone where I then read it. Thunderbird then showed the email as read... however on my device those earlier emails that I read using Thunderbird are still showing as unread... very strange

Android Wear causing battery to quickly drain
I'm currently using a Zenwatch first generation alongside a Samsung Galaxy S6 Edge on Android 6.0.1. Both devices are always fully updated.

The problem is that when my smartphone is connected to the Wear, the battery of the phone drains a lot faster than when it isn't connected. Since my phone is rooted, I'm using the BetterBatteryStats app in order to keep track of my device, and I noticed that when the smartphone is connected to the SmartWatch, the device almost never goes to the DeepSleep state, with the "Awake (Screen Off)" consuming almost all of the device processing time (this doesn't happen when the smartphone is disconnected to the SmartWatch).

My thinking is that the Notification Listener it's keeping the device from going into the DeepSleep mode, so the smartphone can send the received notifications to the SmartWatch. There's something I can do in order to get a better battery life when my device is connected to my SmartWatch?


问:
How can I make Android M stay connected to a weak wireless network?
I recently switched from an older device running CyanogenMod 11 (Android 4.4 / Kitkat) to a newer device running CyanogenMod 13.1 (Android 6.0 / Marshmallow).

Both with this device and with others, I've found that the newer versions of Android are much less willing to connect, or to stay connected, to WiFi networks with a weak signal strength.

I assume that this is due to Android 6.0's renewed focus on reducing power consumption… but it is a problem for me because my device often has a weak WiFi in many parts of my workplace. This was not much of a problem under Android 4.4, but causes me to lose my connection frequently under Android 6.

I remember that stock Android 4.4 had an option to "Avoid wireless connections with poor signal strength" or something to that effect, but there seems to be no such option in Android 6.0.

Any good way to convince newer versions of Android to connect to weak WiFi signals?

UPDATE: Seemingly-related bug report, wherein many other people complain about the removal of the "Avoid poor connections" option. https://code.google.com/p/android/issues/detail?id=81843

Music players don't see my music
I loaded a bunch of music onto my Samsung Galaxy 6.  The songs are there because I can find them using MyFiles and can click on them to play them individuals.  However, every music player app I have tried does not see these files so I have no control over them to do things like create playlists.  In the MyFiles app they are in a folder called Audio and all mixed together.  DeviceStorage/Music contains the actual CD names but when those folders are opened in music apps, it says no files. I can actually play them from the Samsung MUSIC app but bizarrely this is accomplished by selecting "Verizon Cloud" from the menu and it is always going on about "waiting for backup".  I have tried 4 different music apps and none of them seem to be able to locate my Audio folder which I see in MyFiles.</p>

No network connection when hanging up a call
Whenever I end a call the system becomes sluggish and non interactive for a brief moment, then I get the message "No network connection", and the call ends.

This happens every time.

Software: Android 7.1.1, Resurrection Remix Nougat, RR-N-v5.8.2-20170218-n7100-Milestone, kernel: 3.0.101-lineage-gf497f6e

Hardware: Samsung Galaxy Note 2, n7100.

I've just moved from Cyanogenmod, I did not have this problem before. I've had the problem ever since installing RR.

Perhaps unrelated, but every time the power button is pressed there is a few seconds delay before the screen actually turns on. This also was not a problem before, not with Cyanogenmod, not with the stock Android that came with the device.

What is the cause of this/these issues?

Battery drains on airplane mode when there is no cellular reception
I always turn on the airplane mode on my phone running Android 5.0.2 before I go to bed. It's working great as there is at most 10% drop in battery percentage(usually around 6%). I have noticed a problem with my phone and I think it shouldn't happen(this is my first phone). When there is no cellular reception, my phone will try hard to find one and the battery starts draining(which is normal), but it still tries to search for reception even I enable airplane mode, which is the odd part. It is okay since my phone is able to receive reception after a few minutes.

Few weeks ago, my phone completely died overnight with airplane mode enabled. I am sure I have closed all running apps, and I didn't have GPS and Bluetooth on. I tried to search online but I found no clue.

This happened again today. I could feel that my phone was warmer than usual and I knew something must have went wrong.

Is there a way to prevent my phone from searching for cellular reception on airplane mode? Or is my phone faulty? I already have Always allow scanning - Let Google Location Service and other applications scan for Wi-Fi networks, even when Wi-Fi is off disabled long time ago but I don't think it has anything to do with my problem.

Cannot use all cores on Honor5C (Android 6.0)
I am working on a rooted Honor5C phone in order to benchmark some computer vision algorithms. The basic idea is to see the phone as a all-in-one well optimized embedded board giving you all you might need in an IoT context (wifi, lte, camera, storage, performance...).

For those who might not know, the Honor5C has two ARM Cortex-A53 quad cores running at different speed. When reading the net, it seems one group is used for performance and the other one for battery saving.

During the different benchmarks I tried to do on the phone, it seems I couldn't get all the cores running for my application, basically a C++ binary. So I've tried running a simple script and check with top the core usage. Here is the script:

```<code>#!/system/bin/sh
i=0
while : ; do
  i=$(($i + 1))
done
</code>```

When executing 8 of this script, only 50% of the CPU maximum usage is used letting me think only 4 out of the 8 cores of the phone are used for this.  Does the OS limit their use ? Is there any solution to force the use of the available cores ? Has anyone encountered this issue ?

Rampant Google Play Services and Location problems since Nougat 7.0 Update on LG Stylo 2
I have an LG Stylo 2 running android on Virgin Mobile.

Since the Nougat OTA has been rolled out a week or two ago, I have had numerous and far-reaching problems with the device, and troubleshooting each of these problems individually has been unsuccessful.

The worst/most annoying are:

Constant "google play services has stopped" or even "google play services keeps stopping" messages.

Frequent messages "authentication is required" messages in the play store asking me to log into my google account, though I am logged in (this also happens in other apps, and it won't take me to a login screen)

Huge issues with location and GPS. Location is on, and when I try to toggle the mode to "high accuracy", it automatically toggles back to "GPS only".

Same with the Qualcomme IZat performance improvement service:

When I turn it on, it just turns back off. GPS occasionally works with google maps if I boot up the GPS status app, but will not work at all with location-based apps like "Pokemon Go".

I am also unable to use the LG backup service.

Things I have tried:

Rebooting phone/taking out the battery multiple times (this actually makes the "google play has stopped" messages more frequent after reboot for a while).

Clearing data and cache for google play services and google play store, as well as all cache on the phone, multiple times.

Uninstalling and reinstalling all of the apps with issues, including google play services and google play store.

Disconnecting and reconnecting my google account (this gave me numerous errors trying to reconnect the account

It took me many tries. and I was worried I would never be able to reconnect the account initially.

"Force Stop" Google Play Services and Google Play Store

Toggling Airplane mode and location on and off.

Checking for updates to Firmware/Phone etc. Daily!

Any help would be greatly appreciated.

问:
Emulator startup issue
I am trying to run a standard AVD (ARM, empty layout, other settings as proposed by Android Studio) on the emulator. Enabled -verbose, -debug all and -show-kernel modes.

The emulator boots, but ends up in complaining that it cannot connect to a certain socket (127.0.0.1:1970). I tried to open a TCP socket at this port, and got a message from SDKCtl multi-touch - it is trying to establish an handshake.

Does anybody know a workaround, or may at least explain what SDKCtl exactly is, and what it is trying to connect to?

I am on a Mac with El Capitan.

UPDATE

I found a workaround. Just use, when starting the emulator, the option:

```<code>-screen no-touch
</code>```

At this point Android boots (very slowly), the device screen is not empty anymore, but a "process system isn't responding" message appears, and the system stays there.

SECOND UPDATE

In the log from the emulator, I noticed this error:

```<code>goldfish_fb 9010000.goldfish_fb: coherent DMA mask 0xffffffff is smaller than system GFP_DMA mask 0xffffffffffffffff
</code>```

THIRD UPDATE

If one does not issue the -screen no-touch option, and waits a lot, in the end the virtual device boots, with the "process system isn't responding" message. At this point one may click on "wait" on the device message. And then the device seems to work. But the errors in the log are still there.

delete operation are extremely slow
For some reason, moving files from my Nexus 5X to my PC takes huge amounts of time.

The copy "part" of the move operation is pretty much as fast as on any other Android device I've used (I can see the files actually being successfully created at the destination folder on my PC), but then, when the deletion "part" takes place (my indication is that all the files have been successfully copied and the progress bar reaches almost the end) -- the Windows File Explorer instance which handles the source folder just hangs, for a really long time.

For instance, when performing a move operation of 50 images, with an average size of 4MB each -- the copy "part" takes a few seconds, while the deletion "part" takes more than 5 minutes.

My question is: are there any specific tools, using which I can pinpoint the problem, or see a detailed log/real-time statistics regarding the deletion operation?

I'd appreciate any suggestions regarding the situation, which is obviously really problematic.

I've tried this on multiple laptops.

An important detail regarding my Android OS -- I have more than 29,000 images on my device (my entire WhatsApp history, since 2011). Maybe it has such impact on the file system?

I've attached a screenshot of the status bar and the "not responding" File Explorer window, during the deletion "part" of the move operation.

Unbrick a non responsive micromax aq4501
So here's the situation. I had a micromax aq4501 which constantly gave me errors like apps have stopped working. So I tried to factory reset it. As soon as it rebooted into recovery mode a screen appeared saying - 'Erasing'. It would reboot again and again on itself and say the same - 'Erasing'. Whatever i tried to do, pressing power button, volume down/up plus power, the same 'erasing' screen greeted me and then it would reboot again in a loop. So I decided to use SP flash tool to flash stock rom. Flashed it. Nothing happened. Same screen. So I tried formatting my phone using sp flash tool. I selected Format whole flash except bootloader option. But now my phone has become unresponsive. Hardware buttons dont do anything. Phone still gets detected in sp flash tool so I tried flashing rom again but nothing happens. Phone is like dead, only my PC still detects it in sp flash tools. What should I do now.</p>

问:
Android phone won't connect to WiFi when Laptop off
A customer has a weird problem:

After he switches on his router/DSL-modem, his Android phone won't connect to WiFi. When he turns on his laptop (connected by LAN to the router), the phone suddenly is able to connect to WiFi.

When the laptop is subsequently turned off again, the phone stays connected to WiFi.

So, once the router is switched off and on again, WiFi only becomes available to the phone when the laptop is turned on (and then off).

Apparently this started to happen a week ago, without any changes in settings. I checked all his router settings remotely and all seems to be in order. He doesn't have TeamViewer on his phone, so I couldn't really check all its settings, but nothing is supposed to have changed.

Hence, all suggestions welcome.


问:
Bluetooth scanner app don't yield results
I have a OnePlus One with Cyanogen based on Android 6.0.1 as well as an old Samsung Galaxy Tab 3 with stock Android 4.x.

In addition, there is a TV with Bluetooth, and one of this modern Bluetooth speakers.

Both of my Android devices list the three other devices in its Bluetooth menu.

Now, I've tried out several bluetooth scanner apps like

BLE Scanner

Bluetooth LE Scanner

Bluetooth Scanner

Bluetooth 4.0 Scanner

but none of them lists any bluetooth devices. The last one crashes my phone...
May be, the first two scan for BLE devices only, but the last two seem to scan for both.

Does anyone know what the problem is?

(I'd like to get the RSSI to evaluate if it is suitable for a special problem at work, and naively thought each scanner could simply provide it.)

EDIT:
The phone is running Cyanogen 13.1.2.

GPS is on, and the apps have granted permission to access bluetooth and GPS.

I also thought there may be a problem with my phone, but it's exactly the same with my tablet.

And as said, the phone as well as the tablet do list the TV and the speaker in their menu, can connect to them, and play music etc. It's just that the BT scanner apps just list nothing.

(By the way: Many scanners want GPS to link bluetooth devices to position, but why is GPS needed to detect bluetooth devices?)

EDIT 2:

Because my problem drives me nuts, I just wrote my own Android Bluetooth scanner. Before giving it GPS access, it doesn't list anything, but after, it just works.
It's quite interesting, from the apps listed above only two want GPS access...

Oh, and no idea yet why exactly GPS is needed, but the API just requests it.

问:
Import Contacts from .vcf file (NO google. Ever)
I've looked around... (stack exchange) and no former Q? seems to apply.

I would like to import the contacts so that the NUMBER (and email, if it exists) is listed beneath the contacts name? Instead of a jumbled mess?

The problem could be related to a difference between how android v4.4.2 (old phone, where the .vcf file was generated) and v4.1.2 (new phone) handle contacts. The (stock) app behaves differently.

I do NOT use google for anything, for security reasons. Instead, I use Fdroid apps or apps I've downloaded to PC then transferred and then side loaded. In other words, there is NO google account in my phone (ever)

My Old Phone got stolen, but fortunately I'd backed up the contacts from the phone using

[Frdoid, Export Contacts][1][1]: https://f-droid.org/repository/browse/?fdfilter=contacts&fdid=am.ed.exportcontacts

These save to "contacts.vcf" in a directory of your choosing, I exported mine and saved externally on PC hard drive.

Trouble is, using

[Import Contacts, Fdroid][2][2]: https://f-droid.org/repository/browse/?fdfilter=contacts&fdid=am.ed.importcontacts

The import does happen, however the contacts are scrambled. There is a contact for each NUMBER, and a contact for each NAME, but these have become disconnected.

I've checked the *.vcf file, which appears to be a variant of a comma or semicolon delimited *.cvs file... I can't figure out what's going wrong.


问:
Is my Galaxy 10.1 Tablet dead forever, or can I bring it back to life?
I have a Samsung Galaxy Tab 10.1, 16GB, wifi only version, GT-7510. Bought in the US.

It was running a rooted version of Lollipop for a long time with no problems, and then in the last couple weeks, I started to constantly get pop errors at random times saying, "Unfortunately, Google Play services have stopped." Also, Google Play wouldn't load.

I tried a factory reset, and wiping cache, and that sort of thing, but none of it helped. So, I thought I'd try a new ROM. I saw there was a version of Android 6.0.1 available, so I thought I'd give that a whirl. Here's where everything went wrong. I tried installing the ROM, and it failed. Then I noticed that my version of TWRP might be too old. I had version 2.3 or so, and maybe the ROM I was trying to flash needed a higher version. So, I got the latest TWRP, which version 3, and tried flashing that using Odin from my Windows 10 computer.

And that's when everything died. In the Odin interface, it said "FAIL". Then, after that, I couldn't boot into recovery mode. I tried reflashing, I tried finding stock ROMs, and, after following some advice on the web, I tried flashing a PIT file. Nothing worked.

Currently, the situation is that even though I have it turned off, the screen comes on intermittently and says "Firmware upgrade encountered an issue - Please select recovery mode in Kies & try again".

I can hold down the volume down and power button and get into download mode (but not recovery). If I go into download mode and try to flash from Odin, I get the following error.

I've attached screenshots of the ODIN output and the error on my Tablet.

I've tried different versions of Odin, I've double checked every file to make sure I've got the right file for my device, I feel like I've done everything I can do.

Is my Galaxy 10.1 permanently bricked? Or is there any way I can pull it back from the brink?

The red text in the bottom error screen says:

Fail to download [51505][Date:8970.0] > Part 2560(/2560)]
  (2KB unit)

Tegra_nand_Write: Error to DownloadPartition_odin![err:0xffffffff]

Update: It seems I can't turn on the device anymore. No matter how long I hold down the power button, or if I combine it with holding down either volume button, the screen does not respond. There's no charging indicator on screen if I plug the USB cable in, so I can't tell if it can take a charge or not, but I have tried leaving it charging over night.

Anyway, whatever the cause, the device now seems completely unresponsive. So, unless someone has one last thing I can do to try and resurrect this device, it looks like it is bricked and I'll be giving it away.

Gboard: select current word, and compound words in German language
I'm using gboard from Google and I absolutely love it. I just have two questions about it because I come from using Swype which has a lot of nice and useful features to quickly  which i miss heavily:

Is it somehow possible to easily create compound words like it is in swipe? In the German language we often concanate words together. Right now, I have to insert two Words, and afterwards remove the space in between and change capitalisation. It's cumbersome

Is it possible to select a whole word using some shortcut on the keyboard? Currently, to change the capitalisation of a word or to remove some word, I need to select the whole word before pressing backspace or shift keys. But when I click into the word only the cursor is placed in between. So i always need to long press it and to select the whole word from the os context menu... it's cumbersome especially for the case of deleting a wrongly written word afterward.

Thanks a lot guys

问:
Device shows up in fastboot and recovery, but not in Android?
I have a Motorola Moto G 2014 device. The USB connection behaves very strangely.

If I boot into fastboot, the device shows up correctly via fastboot devices

If I boot into recovery, the device shows up correctly via adb devices

If I boot into the OS (I've tried a whole bunch of different ROMs), the device doesn't appear at all via adb devices. It doesn't even appear as a valid USB device.

To debug it, I've run lsusb -v and checked the output.

In fastboot the device shows up like this:

```<code>Fastboot titan S:

Product ID: 0x2e80
Vendor ID: 0x22b8  (Motorola MDS)
Version: 1.00
Serial Number: [removed]
Speed: Up to 480 Mb/sec
Manufacturer: Motorola Inc.
Location ID: 0x14100000 / 21
Current Available (mA): 500
Current Required (mA): 500
Extra Operating Current (mA): 0
</code>```

In recovery the device shows up like this:

```<code>Moto G 2014:

Product ID: 0x2e76
Vendor ID: 0x22b8  (Motorola MDS)
Version: 2.28
Serial Number: [removed]
Speed: Up to 480 Mb/sec
Manufacturer: Motorola
Location ID: 0x14100000 / 29
Current Available (mA): 500
Current Required (mA): 500
Extra Operating Current (mA): 0
</code>```

But once I boot into the OS... nothing! adb devices shows nothing.

I've enabled USB Debugging, I've tried switching the USB mode from/to MTP and so on. In my mind, though, none of that's relevant if the device doesn't even appear over USB!

What's frustrating to me is that I can't determine whether it's a software or a hardware error. If it's a software error, why don't any of the ROMs I've tried work?

I'm assuming it's a hardware error (I bought the device used and it has a cracked screen), but how could it be that the device works properly in fastboot and recovery mode if there's a hardware issue with the USB?


问:
Did kingoroot install bloatware on my phone? Or is this a legitimate android locksreen?
Long story short, I have rooted my phone in order to resolve 'low on internal storage' issues (turned out the cache folder grew to almost 2GB). I have used kingoroot as suggested in this answer and it worked nicely.

However, shortly after the rooting, I noticed I had a new lockscreen I've never seen before:

Before the rooting I had what I believe is the official Android lockscreen, where you slide your finger from the center of the screen to a lock icon, camera, or unread messages if you have any.

I certainly don't remember installing a lockscreen app, but after rooting and cleaning the internal storage I finally was able to install updates in Google Play, and there were quite a few of these.

How can I find out where did this lockscreen came from? Is this how Android lockscreen looks now on Android 4.4.2? If not, is it expected to get unwanted software when I root my phone? And finally, how do I uninstall it?

Edit: the method for replacing KingoRoot with SuperSU didn't work. I've got error messages about non-existing files, and SuperSU started but couldn't update the binary.

GMail "couldn't sync", though I can watch long videos in YouTube
I have run out of space in my smartphone (got the message Storage space running out: Some system functions may not work). I know this is defined as a threshold of 10% of internal disk space (8 GB). So, I have ~ 800 MB of free space. I can watch YouTube videos in YouTube app (I'm watching Persepolis right now, which has more than one and a half hour). But GMail says it just "Couldn't sync", so I cannot see nor send any new emails.

If there's an emergency and I need to communicate by email, I just cannot, because Google has no option besides "sync" the GMail app. It could obviously show new emails as plain text, without saving anything to disk.

Is there any reasoning behind this absurd (emails are much smaller than a 1:35h video), or is it just another planned obsolescence behavior?

Reading an ICS Calendar file in Android 7
When I book a travel, the company sends me a reminder with one or more ics files that work fine with Microsoft Outlook.

I buy almost only from computer, because official Android app does not offer the same discounts: I mean, this specific rail company almost sells regular-price tickets via app, but if you browse their website from desktop computer you may be able to find discounted prices for the very same journey. Plus, there is no ticket synchronization with this specific vendor even if I use the same account on the website and application.

I can't use anymore Local Sync for Android (R.I.P.), so I end up with a reminder email message into my Outlook/Gmail app with those ics files attached.

When I open the ics file with Android Calendar it won't import it. Also worth to note I don't use Gmail address. The Gmail app is configured with my IMAP mailbox to get the rail tickets.

Question: with vanilla Android 7, is there a trick to import an ics calendar file into Android Calendar? Didn't Google add support for standard ics files into their app? Is it possible not to install yet another app?

Wifi Hotspot/Tethering Unstable (Android 7, Xperia Z5 Compact)
I have a Sony Xperia Z5 Compact running Android 7.  The Wifi hotspot/tethering functionality has never been perfectly stable, but in recent weeks/months (I think since Android 7) it has become awful.  What happens is I unlock the photo, pull down the notification screen and tap the hotspot icon to turn it on.  The hotspot icon then shows in the top notification for about 2-3 seconds before vanishing again (I presume: crashing silently).  If I turn it on again sometimes it also vanishes within a few seconds, but it may then stay on for a while.  However, it stops relatively frequently (several times an hour).

It does not appear related to what devices are attached (it crashes before any other device has connected, after all) nor to the mobile data connection (which is usually working fine with good signal at the point it crashes).  My provider does allow tethering, and anyway it's the hotspot wifi functionality on the phone itself which is cutting out and dropping the wifi to the tethered laptop, not the onward connection.

Obviously I'd love to know the solution directly, but even if not: is there any way I can debug what's happening by viewing system logs or similar?  Phone is not rooted and I'd prefer not to root it.

Phone disconnects from USB after 5 seconds on Windows
My phone recently underwent continued exposure to water (in my pocket during a heavy storm), and after drying it out, I have a problem with its USB port:

When connecting the phone to a Windows computer, it indicates charging, is detected as a device by the system, but it is not possible to browse its files. But after approximately 5 seconds, it is completely ejected and stops charging.

When connecting to a Linux or Mac computer, it works flawlessly, charging and able to transfer files.

I suspected it could be some sort of short causing an overload and the motherboard shutting down the port, but does not seem to be the case, since when monitoring the current (with an app in the phone, and an USB volt+amp-meter it looks to be well within range of the expected values.

After ruling out overload, I thought that maybe the data bus could be damaged, but upon testing on a Linux, a Mac and another Windows, it worked perfectly, even transmitting big files to check if it would fail at some point succeeded. Seems this is an exclusively Windows-related problem.

It could be the cable, but after testing with a different one, the same behaviour was observed (works on Mac/Linux,  disconnects on Windows).

Any ideas how to fix this? It's a bit annoying since I usually use my Windows machine to charge the phone.

I tried shutting the phone off after flashing and booting directly into recovery mode as some people suggested, but it makes no difference. Yes, I've turned off the option in developer options to update cyanogen recovery, but 12.1 ignores that setting anyways and rewrites any custom recoveries anyways.

Android internal storage sd card clone
My wife has a Moto G 3rd Generation which had the SD card set to internal. The phone has had problems reading the card, and unfortunately she hasn't had everything set to back up so there are some things on the card we would really like to recover.

I have put the card in a card reader and ubuntu is able to read it but unfortunately can make no sense out of it due to the android encryption.

The phone isn't rooted, and as far as I can tell Dirty Cow exploit will not work to get temporary root so I have no way to get the encryption key off the phone (I think?).

I wondered if cloning the card might work so have purchased an identical card and tried to use dd to copy it. Weirdly dd is reporting this:

dd: error writing '/dev/sdd': No space left on device 7818241+0 records in 7818240+0 records out

I have tried to allow truncate at the end (lose the last byte) or skipping the first byte and neither of these has resulted in a card that is readable.

I have also tried another make of card (same size 32GB) and have the exact same problem.

Do I have any options left? Is there any way to work out given the encryption where one byte could be safely removed, perhaps only corrupting a file.

Any ideas greatly appreciated.

Many thanks in advance.

Help me identify this tablet and whether there are custom ROMs for it
I was gifted this one device that I can't find any information online on, despite exhaustive searching.
Internally, the tablet claims the following:

Model number: S7Q

Android version: 4.2.2

Kernel version: 3.0.36+ twp@server71 #525

Build number: S7Q_ZTE_PAD_EN.V2014.4

Naturally from this I would assume it is some ZTE device that would be called S7Q , but my searching of the internet only turned up that term a couple of times, both cases of a lone person on the XDA forum asking "what is this?" and getting no real answer. More searching seemed to suggest it was a Blade S7, but Ask Mr Pigfish, a software meant to identify a ZTE Blade model, reports that I have an "unknown model".

I'd really like to figure this one out so I could root it and setup a custom ROM, and I'd appreciate any help!


问:
Can a phone support lte band 41 but not support band 38?
The only difference in Google Pixel's versions for North America and for the rest of the world is their support for different lte bands and carrier aggregation.

E.g., in tech specs (https://madeby.google.com/phone/specs/) it is stated that the US version only supports B41 for TDD LTE, while RoW version supports B38/39/40/41

However, I found in Wikipedia (https://en.wikipedia.org/wiki/LTE_frequency_bands) that band 38 is actually a subset of band 41.

Does this mean that the US version of Pixel supports b38?
Will LTE work on US version of Pixel if the carrier provides only band 38?


问:
Skype sent messages I didn't send
On my laptop, I played a video on YouTube. In the morning I looked on my Android phone and discovered that the video had been sent, in Skype, to about six of my contacts.

I'm not sure if the sending occurred from my phone or the laptop, but it's more likely from the phone for two reasons: I'm pretty sure the laptop was off, and my phone has been acting a little erratically. On the other hand, I didn't play the video while on my phone.

1) Is there a way to confirm which device sent the video?

2) How can I recall, unsend, or delete the video from the chats? If (on the phone) I select and hold the message, the pop-up menu does not include "edit" or "delete".

3) Does this sound like malware behavior? I'm scanning with "Lookout" but is that the best type for this type of thing?

How do I stop Google Now from opening multiple chrome windows?
I have an S5, android version 6.0.1.

Whenever I search from Google now, it starts to pull up the results and then immediately appears to be opening another window with the results and then another--all with the same results. It's extremely annoying. If I have used voice to do the search, the google assistant starts to tell me the answer and then is cut off mid-sentence by the second opening of the results.

I haven't been able to get a screen capture of this happening. But I have noticed that when it first starts to happen, I see new text in the search text box. It is something like: "http://www.google.com/?search="search text""

I might not have that exactly right but you get the idea. It's almost like another query happens automatically.

My wife has the same phone and OS and has never had this happen. I have tried reinstalling Google Now. This has no effect. My tablet also has Google Now and this never happens there either.

Please help!

I am not sure if this is the correct place for this post. If not kindly refer me.

A Samsung galaxy S2 device randomly launches apps (any kind). these apps immediately relaunch after forcing stop. when media player launches repeatedly the battery drains very fast and the cellular is practically unusable.

Is it possibly a touch screen issue?

I have tried factory reset to no avail.

This problem just started with no special update, root or installation as a cause.

How can I run a consistency check on my removable MicroSD card?
I own an Android device with a removable MicroSD card. The card uses either FAT32 or ExFAT technology. These are "non-journaling filesystem" technologies, so the data on the cards can become corrupted in certain cases.

Perhaps I should run a consistency check (e.g. fsck / Chkdsk / ScanDisk) every so often.

问:
Can a micro-SD card contain some encrypted and some unencrypted files?
I recently upgraded from Samsung GS5 to GS7 edge.  I was encrypting the SD card in the old phone.  I believe that it was decrpyted when I removed it, because it was on and running, and I unmounted it from the settings menu.

However, several times I have restarted the GS7, entered my decryption pin, and then gotten a message that it cannot decrypt the storage because it was encrypted on another device.  Strange, but then I have been able to open folders and files (photos) stored on the card, right away, and without taking any further action or seeing any further message about decryption.

Is it possible that there could be a partitioned space on the SD card that is still encrypted, hiding files from me?  Or is this just a weird bug?  I would like to know before I return or sell the old phone, in case I still need to do anything with it.

How can I migrate my Palm OS memos over to Simplenote?
There's an old PDA/smartphone operating system named "Palm OS". It's included with PalmPilot, Palm, Visor, Tungsten, Zire, Treo, and Centro devices.

One of the apps which comes with a Palm OS device is called "Memo Pad" or "Memos". It synchronizes with desktop PIM software such as Palm Desktop or J-Pilot.

On my Palm Treo, in my Memos app, there are about 2200 memos. They're all plain text. Some of the memos hold dozens of kilobytes of text. In total, my MemosDB-PMem file is 6.5 megabytes. I still use the Memos app regularly.

I think I'd eventually like to migrate all memos over to Android.

Evernote is nice, but as Wikipedia writes: "The service has experienced several cases of losing customer data."

Also, the free version of Evernote for Android doesn't work so well during times when you're offline. It works better if you pay for a monthly Evernote Plus subscription.

Finally, I know that Evernote supports file attachments, voice memos, photos, and other bells and whistles. But I don't need these features.

I think I'd rather use Simplenote, which I hear works well for plain-text memos.

How to block websites on Android (for free) without root?

I'm trying to identify and locate the /dev/ pseudo-file that corresponds to the onboard, hardware GPS devices; installed in most modern Android smartphones, and tablets. I know that it probably varies sometimes, but the vast majority more than likely use a standard, logical name.

If you have no idea what I'm talking about; some examples of common, logical names for other kinds of hardware that you might recognize, are:

tty0, mouse0, event0, eth0, wlan0, sr0, video0, media0, bus0, usb0 gps0, disk0, sda1, sdb2, sdc3, and so on.

Most of these live inside /dev/, and it's subdirectories; such as /dev/input/.

OnePlus One bootloop, not related to flashing
My phone entered bootloop during charging, restarting doesn't solve the issue and I can't boot to bootloader, only "fastboot mode" text is stuck on screen. TWRP recovery can be accessed and I've tried clearing cache & Dalvik cache. I haven't flashed nor installed anything in months (CyanogenMod 14 installed), the phone has only been used for calling and messaging since late 2016. I've also had a similar issue before, happened during charging as well.

I found a potential fix by Ricardo Cerqueira of Cyanogen Inc., shared by Android Police:

While your phone is booted to TWRP, run these commands on your
  computer:

```<code>adb shell
make_ext4fs /dev/block/mmcblk0p15
</code>```

Here's the output of the command:

```<code>make_ext4fs /dev/block/mmcblk0p15
Creating filesystem with parameters:
    Size: 33554432
    Block size: 4096
    Blocks per group: 32768

    Blocks: 8192
    Block groups: 1
    Reserved block group size: 7
Created filesystem with 11/2048 inodes and 1166/8192 blocks
</code>```

Once everything is over, the OnePlus One should be restored without
  any data loss.

I get identical output when running the commands, but the phone is still persistently in bootloop.

When reflashing my ROM the installation fails. The installation processes finishes far faster than normally (around 10 seconds) and this error is displayed twice in TWRP log (in red):

```<code>E:unknown command [log]
E:unknown command [log]
</code>```

What should I try and is the cause of this issue now known?

Very low battery-life in specific WiFi
Hello fellow Android Enthusiasts.

I have a problem that has been bugging me for a very long time:
Whenever I leave devices at my workplace overnight, the battery is completely drained the next day.

This occurs on any Android device and any of those devices' batteries last completely normal in any other location. This is exceptionally strange with tablets which batteries last for weeks in standby mode.

The devices are not connected to anything over night via cables.

The only thing I can think of that is different between work and anywhere else is the WiFi.

Those are my devices that I could observe the behavior on:

Sony Xperia Compact Z5

Samsung Galaxy Tab S2

Google Pixel C

LGE Nexus 4

Google Nexus

The range of Android Versions goes from 5.1 to 7.1.1.

Can such a behavior be caused by the WiFi? I was thinking of connection loss and reconnection iterations. But I think I would have noticed such problems while being at work. Any other ideas out here?

Minimum required apps for Android AOSP?
I am building AOSP Android 5.1 to run on custom hardware that should run a single APK application (as a launcher). The hardware has a camera, speakers, microphone, wifi and LCD screen. There is no cellular or phone functionality. The device is similar to a tablet.

My goal is to create the minimum viable build of Android with no extra apps, (such as Browser, Google Apps etc.) except the bare essentials. This build of Android will launch a single Launcher application. This can be thought of as a kiosk type device.

Note: I would like to keep a few apps for debugging purposes such as Settings, Camera and Sound Recorder, but these will be removed eventually also.

Huawei Ascend G7 Stuck in Fastboot & Recovery
A few days ago, I must have been pressing some buttons by accident and my phone entered fastboot & recovery. Restarting does nothing, it doesn't matter what combination of buttons I hold down. Every time, it starts up with the standard Huawei boot logo then a black screen comes up saying boot image verify failed and then it goes to another screen that says:

```<code><br/><br/>
"FASTBOOT&RESCUE MODE<br/>
 Please Connect USB Cable to your Computer and Open Hisuite<br/>
PHONE locked"<br/><br/>
</code>```

I've tried connecting to Hisuite, but my PC doesn't register that my phone is connected. It does charge the phone, though, so not a problem with the cable/USB port. I suppose I didn't have USB debugging enabled? Can you enable it from PC?

My phone isn't rooted, by the way. Also, you can't remove the battery from this phone without messing around with hot air guns, etc.

I've tried letting the battery run dead and then charging it again and restarting the phone, but nothing different happens.

I don't know much about phones, really, any help would be appreciated!

Galaxy Edge 7 edge lighting reminders
How would I go about setting a repeating reminder that just lights up the Edge on my S7 Edge?

I have a need for a reminder that just lights up the edge in the same way as it does when the phone is face down and you receive a call (Edge Lighting in Settings).

I have to do something every hour but I don't want the phone to vibrate or make a sound whilst I am in the office do as not to distract my colleagues.

Ideal situation:

I set a reminder for 9am to repeat every hour

At 9am, 10am, 11am, etc. the edge lighting comes on with no sound or vibration

Unable to get past odin mode
I have a Galaxy S5 that had Cyanogenmod + CWM for about a year. The other day it started randomly shutting down and getting stuck in the bootloader screen ("SELINUX ENFORCING" + Samsung logo). No matter what I did it kept getting stuck in the loop of rebooting and then going back into this mode.
I couldn't even get it to load Philz Touch in order to try and flash it.

In the end I did a factory reset but this didn't help. I tried to install TWRP via Odin and Odin says "PASS" but when I start the phone all I get is the same bootloader screen and no TWRP.

When I try to run fastboot all I get is a message saying "waiting for device" even though it does show up in Odin 3.

I am trying to install the latest version of Lineage but need to get TWRP installed first.

Currently the phone is in a crash loop on the Samsung logo screen with "RECOVERY BOOTING" "Set Warranty Bit: recovery" printed in the corner

Any tips?

Problem in usb debugging
I wanted to move all inbuilt apps on my Samsung Galaxy On7 to the sd card to free up space. To do this, I followed this site.

However, even after enabling USB debugging, the desktop is not being able to show the device in adb devices list. I had previously uninstalked all android emulators (like BlueStacks) and have the full android sdk tools and Android versions 5.0 to 7.0 installed on my computer.

Anyone can suggest why this happens?

Any other way to move inbuilt apps to sd card without rooting the device?

What are the problems of rooting device?
I want to root my android device (Samsung Galaxy On7, 6.0 Marshmallow) to move my inbuilt apps to sd card to free up space.

I'm doing this as per this site:

What are the potential problems I might face?

Will I lose data?

Is this process reversible?


问:
Nexus 6P (7.1.2) thinks car line-in is headset
My Nexus 6P thinks my car line-in is a headset. It shows some notification about using a headset when I plug it in. The standard double ended 3.5mm jack cable doesn't have a microphone ring so I'm not sure what's causing this behaviour. The car also doesn't support using a mic over this connection.

This behaviour stops the microphone on the phone being used because it is expecting the mic on the non-existent headset to be used. Wifi and Bluetooth turned off and not connected to USB. It doesn't do this with any other 3.5mm connection, such as to normal headphones or into a stereo.

Is there a way around this? What is causing this?

WhatsApp storage problem
My problem is that the WhatsApp stores all the data in the phone memory, which is almost used up.

If I move the WhatsApp folder to sd card, then I'll not be able to access anything from the app.

Is there any way in which I can move the files to sd card but still keep it linked with the app?

问:
Pandora app fails to open after being used
New phone, LG V20 from T-mobile. Android Nougat (7.0 right now). Latest Pandora app.

The problem first manifested when I expected Pandora to wake me the next morning. It didn't. Checking my phone the Snooze/Stop circle buttons were there on the lock screen as if Pandora was running, but there was no music or even the tone Pandora plays when it can't access Internet.

Later, using Pandora during the day I found that if I'd used Pandora closed it (either by pressing the X in the notification or just by leaving it alone and paused long enough the OS closed it) and then opened it several hours later or the next day, the app would begin loading but would not progress beyond the splash screen.

I have removed the app and reinstalled. I have cleared cache/data.

I have not reset the phone.

Silent hours are set up but not for alarms and they stop before the alarm goes off.

Update 1

I set the phone Clock app alarm for the same time as the Pandora alarm. The phone alarm will go off briefly, then Pandora will start playing music, then once the first song is done on Pandora the phone's alarm cuts over Pandora and starts sounding again.

Odd.

I also changed Quiet Hours so they end 5 minutes before the alarm goes off (Alarms are allowed to sound through Quiet Hours already).

Yesterday I completed a full remove/reinstall of Pandora but forgot to re-enable the Pandora alarm. I'll do more testing today.

Future steps involve a full wipe/reset of the phone (don't really want to do this for another month though, after I've got the full unlock from TMobile completed).

Update 2

I contacted Pandora support. The steps they took me through were:

Update Pandora App to latest version.

Disable any battery saver or task manager. Android Nougat has a built-in Battery Optimzations function, and the ability to allow specific apps to ignore the optimizations. I enabled ignoring optimizations for the Pandora App.

Clear data.

Verify app is installed in local memory (not external/storage card).

Switch between normal and HQ audio (this is a data network-specific setting, and I'm using home wireless, but still switched it).

Uninstall and reinstall.

After completing all these without improvement or resolution, Pandora support asked for details of my phone and software and forwarded this to the engineering team.

Two days later (Monday this week) the Pandora alarm worked perfectly, and again Tuesday. The phone had been running for perhaps 5-7 days this point without a restart.

Wednesday morning the issues reoccurred. The Alarm interface loaded on the lock screen but no sounds playing. Thursday was the same, and battery usage was very high that morning with Android Operating System using the lion's share. I restarted the phone Thursday, and this morning there was also no alarm.

I would advise you to report your own issues to Pandora support so they'll be more aware of the breadth of the issue.


问:
Nougat - Disable settings on lock screen
I currently have my phone set up to automatically unlock when it's connected to my car's Bluetooth, which is super convenient. However, my car's Bluetooth stays active while my car is off, and my phone is capable of connecting to it from almost anywhere in my office building.

So, when I leave my car, I turn off Bluetooth on my phone since I want my phone to lock. But right now, anyone can pick up my phone, enable Bluetooth from the lock screen, and it's instantly unlocked.

Is there any way to select which connectivity options can be changed while the phone is locked, or disable these options altogether?

Alternatively, is there a way to tell Smart Lock to not automatically unlock when connected to the Bluetooth device, but remain unlocked once I've unlocked the phone myself?
