问:
How can I change the Ethernet (IPv4) properties from my Android phone?
So my problem is: I am currently writing an Android application which has to get access on data sent via Ethernet connection. The app is going to replace a Windows tool which is able to receive data from another (automotive) device sent via Ethernet. When using this Windows tool, I have to change my computers Network Settings like shown below, so that the tool is able to set up a connection to the device:

Local Area Connection - Properties - TCP/IPv4 - Properties - change IP adress and subnet mask to the values which fit to the device

Now I want my application to receive the Ethernet signals. I am using a Google Pixel 2 with Android 8.0 and also have an USB-C to Ethernet adapter. I already tried to get an Ethernet connection by connecting to the Internet with an Ethernet cable plugged into my phone (with the adapter of course). So that means, receiving data via Ethernet should be theoretically possible. But I do not know, how I can change my phones Ethernet settings. The phones Ethernet controller also has to apply this certain IP address but there are no options in my phone's menu.

Do you guys know any way how I can change the phone's Ethernet settings/properties?

Night mode: Disable in certain apps
I just got a new OnePlus 5T. (Upgraded from a Nexus 5X.) I like the new Night Mode, as it does natively what I used the Twillight app for in my previous phone. But, I don't know how to make it automatically stop in certain apps. For example, when I'm watching a movie in the evening, I don't want to have its colors be yellow. Is that possible? </p>

AutoHotKey equivalent? (paste timestamp, open app, external keyboard, etc.)
Desktop PCs have AutoHotKey, AutoKey, IronKey, etc. .

But as far as known, nothing compareable for mobile phones.

I would like to be able to do things like:

Instantly pasting timestamp in preferred date format (i.e.20180210115759 or 10.02.2018 11h:59m:19s) using a keyboard shortcut from an external Bluetooth/USB-OTG powered keyboard.

Pasting tinestamp with on-screen keyboard (without any bulky workaround such as copying to the limited clipboard first).

Open/switch to application (e.g. text editor) using keyboaed shortcut.

Ability to launch selected app directly from external keyboard hotkey to take notes using a portable bluetooth keyboard while the phone is still inside the pocket. http://android.stackexchange.com/questions/190819/allow-running-specific-applications-without-unlocking?noredirect=1#comment246822_190819

So I've been trying  to root my Nextbit Robin, but no matter how many drivers I try, it is not recognized by Linux (Ubuntu 16.04) or Windows (10 x64). First time trying to root, so any advice on this would be appreciated. I have tried drivers from Nextbit and Google, with Nextbit's not doing anything, and Google's impossible to install. The drivers that come with Android Studio cant be install through device manager, with the result of either "Best Drivers Already Installed" if i just select the folder, or "Not made for Windows x64 based platforms" if I use the "Has Disk" button. Any and all advice would be great, thanks!</p>


问:
Why a Samsung J3 wont call/text but data works
A friend and I own the Samsung J3 model phone.  Both phones shared this exact problem within a day or two.

The issue was the phone could not call or text.  Neither incoming nor outgoing attempts were successful.  The kicker was the internet still worked without WiFi.  Any outgoing call failed saying there wasn't service.

The problem was resolved by manually switching a setting in 'mobile networks'.  Taking it off the network and putting it back on after a few minutes.

I'm wondering why this would happen to both phones in short time, and why changing that setting solved it.  Maybe the phone had an update that causes a glitch in that area?

Any ideas are welcomed.

Edit: wanted to also add the LTE data was on and operating with no Wi-Fi being used.


问:
Why are notification action buttons laggy?
Let me explain my experience with the Android notification action buttons feature, where notifications from apps (often social media / communication apps) have buttons attached that can be used to like the message, retweet, reply, mark as read, etc.

Inconsistently, but frequently, when I press one of these action buttons, nothing happens for up to 10 seconds. If I don't wait for the notification to react to my pressing of the button, sometimes the button press never has ANY effect. And yet, sometimes the effect is instantaneous.

I have more success with some apps than with others. For instance, Android Messages is pretty responsive, Google Inbox is mediocre, and GroupMe is downright atrocious (I often have to wait more than 5 seconds after pressing "like" for the action to occur, and sending a reply with the action button almost never works).

Does anyone else have this experience? Is it just my phone? Or is it a matter of implementing this feature intelligently?

For context: I have a Nexus 5X running the latest Android 8.1.0.


问:
How can I ensure that files such as photos/videos are stored in the SD card in Android Marshmallow?
I have a Lenovo Vibe K4 Note phone with Android 6.0 Marshmallow. I have formatted my SD card as internal storage. As a result, when I view the file system either through my phone or my PC, both the real internal storage and the SD card appear logically combined under Internal Storage.

I have many apps installed, such as Google apps, that do not allow me to move them to the SD card portion of the logical internal storage, and hence reside in the "real" internal storage only (but that is not my question).

The problem is that when I take pictures or videos, they are also stored in the "real" internal storage. Now, my internal storage gets very quickly filled up, while my SD card is near empty. Moreover, as logically both appear in the file manager as one "Internal Storage" category combined, I am not able to figure out how to move out the images from the real internal storage to the SD Card.

My questions are:

When SD Card is formatted as internal storage in Marshmallow, how can I enforce that certain files are stored in the SD Card? How can I ensure that new photos are stored in the SD Card?

How can I move existing files from the real internal storage to the SD Card?

Pull data from phone that causes BSODS?
Bet you had to read that title twice.

So the title says it all really - I have a Wiley-fox, a poor little thing that has been beaten up within an inch of its life. It cant connect to my Wifi, no idea why, it also fails to recognize SIM cards, but it seems the pins for that are damaged, and I need my old photos. Of course, if you read the title (if you think about it title is an odd word) I've tried plugging it in only to get a BSOD.

While I question why this phone has come from the seven circles of hell, does anyone have any ideas on how i can take my photos and stick them somewhere that doesn't spontaneously combust?

How to make a note using voce command
I would like to make a quick note using voice command.

Something like: "OK Google" ..."make a note" ..followed by the message itself.

Preferably using Google Keep but I am open to suggestions.

What the voice command might be?

I tried several variants of make/take note, or just note, all recognized correctly as far as individual words go, but usually ending in launching Chrome web search or in giving me selection of application to handle note, where "Keep" is one of them. But even after selecting Keep, which is not persisted by the way, it is still not very straightforward to actually dictate the note. There must be a better way.

Android Wear "complication"
I previously had an Asus Zenwatch2. I was able to add a complication (I think that's what the little customize-able data points that can be added to certain watch faces are called) that would display the phone battery. It seemed the source for this was the Asus Zenwatch app installed on my phone.

I have upgraded to a Huawei Watch 2 Classic. I don't see an option to get this or several other useful complications that were available from the Asus app on my new watch.

I obviously don't really understand how these complications work.

Is this something that I could get in a 3rd party watchface or is it not available because it needs to be pushed from an app on the phone (like it was from the Asus app)?

Here is an example of the menu to choose a complication:

some files on SD card show up as 0 byte on Win10
I have a Samsung S7 (Android 7.0), with an encrypted SD card. I copied 3 mkv files via FTP on it. I can play all 3 on the phone without any problem.

When I plugged the phone in my Win10 laptop, only the first file showed the correct size in File Explorer. The other two seem to be 0 bytes, even when I copy them to my HDD.

If I copy these files from the SD to the internal storage of the phone, the file size is shown correctly, and the copied files are usable.

How can this be, how can I correct this behavior?

Write protection of loop device // Read-Only Filesystem
After spending days on that topic I am in need of additional ideas ;)

Facts: MTK6757 / Android 7 / Kernel 4.4.15 / FS EXT4 (No F2FS) / Working Root

I have a fresh and clean 64MB EXT4 .IMG File in /data/adb. e2fsck agrees with that ;)

Problem: Mounting and/or writing to it via Loop Device fails.

What I have checked:

Access rights of the file

Access rights of the block device

Access rights of the destination dir

Manually created the block device

Manually setup via losetup

Played with all options

SElinux Permissive / Enforcing

Behaviour:

It only gets mounted with "mount" because it calls a ioctl BLKROSET (thx  strace)

Mount and /proc/mounts show RW

As soon as I write (mkdir) to it, it switches to RO
(dmesg says Switching to RO cause of Buffer I/O error on dev loop0, logical block 0, lost sync page write)

When I enforce writing it gets written to cache but not to the file

ioctl /dev/block/loop0 0x125d 1 mkdir /sbin/.core/img/test

And now the strange part:

When the img file is on /sdcard it works.

The SE Context is of course different, but i also tried in Permissive.

When the mounting occurs BEFORE Zygote starts or in Recovery, writing fails also on /sdcard (Update: Because during boot /sdcard is not available yet)

Anybody any ideas?

Update:

It gets even more interesting:

Turns out writing to /sdcard only works as long as it is mounted as sdcardfs.

If sdcardfs is deactivated it gets mounted as FUSE properly, but writing doesnt work anymore.

As all the facts hint toward a selinux \ vold \ FS problem, i tried to restage the sdcardfs evironment.

Assign root \ sdcard_rwandu:object_r:sdcardfs:s0` to the file in a different directory.

Doesnt work ;(

Then I compared the selinux policies of 2 devices where it works with the problematic one.
Turns out allow vold block_device : blk_file { ioctl read write create getattr setattr lock append unlink rename open } is completely missing.
But injecting that doesn't help too...

Any experts or suggestions?

Tablet with very long boot time, what can I try?
I apologize if this question is too open-ended, but I wanted to collect different ideas regardless of the specific tablet model.

I've owned an Android 4.1 tablet for quite some time now. When I first got it, the boot time was very quick. Lately, however, it takes much longer to boot. The lengthened time is not spent during the boot-animation, it's spent on the splash screen that appears before the animation.

I have rooted this tablet and am willing to pry deeply into the system files to try and resolve the problem.

Android 7.0 - SD Card formatted as internal storage
My Wileyfox handset recently upgraded to 7.0 and I'm getting nowhere with their support. My SD card is formatted as "internal storage". Despite over 30GB of free space on the card, I'm unable to add new apps or update existing ones and am getting lack of space error messages instead. I've reviewed the list of first aid options and these don't offer any solutions. I'm already using the SD card formatted as internal (i.e. not portable) storage.

WFox maintain that many apps will now not run on SD cards.

However, I thought that this related to "external" / "portable" SD cards and that formatting the card as internal memory would avoid this issue. WFox won't address this question. If my understanding is wrong, so be it, but it would be helpful if someone can answer this query for me.

Using android devices as wired webcams for computers?
I have got myself a new phone, and I wonder - if I could use it as a webcam.
I know there are WiFi apps to stream video, but:
 1. My Wi-Fi network is slow (1-2 MiB/s max)
 2. The resolution, framarate and bitrate of video form these apps is very limited

Since I can access the device through ADB console via USB connection - I wonder if I could stream the video that way into my Linux PC, to then use it as a webcam in OBS Studio for preview and capture?

I wonder if there are apps that expose the phone as a webcam device that can be fully controlled from a PC (exposure, focus, zoom etc.).

If not - do you think creating such an app is even possible?

I guess hardware H.264 encoding is not a problem on the newer phones (mine is OnePlus 5T), and the webcam interface supports that - so it should even manage to push through 4K 30 FPS video if the bitrate is optimized for USB 2.0 transfer - right?

I'm thining about this, becasue the phone I have capures better video than my Logitech C920 webcam, however with the webcam I can do things I cannot do with the phone:

I can store and restore camera settings from PC easily (exposure, focus, zoom, white balance etc.)

I can preview the video in realtime on a big screen

I can capture it with whatever program I want (mostly OBS Studio)

Would it be possible to expose phones in a way that'd make PCs see them just like webcams so we can use them this way? It doens't have to be wireless.

Why "System Update" app of "android 6.0" is draining battery
I am using Yu Yunicorn (5530) android phone. It has android marshmallow update. Recently I noticed when I put the phone on charging it takes long time to charge and never goes to 100%, also during the charging when I looked into the "Settings > battery" it shows "awake" green line throughout the period of charging.

Yesterday when I saw in the battery usage I found that "System Update" app is using 190% of battery and phone battery was draining very fast. When I forced stop the "System Update" it increased the battery life and also lets the charging up to 100%. When I put the phone on charging the "System Update" app starts and that slows down the charging. Also when I remove the phone from the charging it again starts "System Update" app. So every time I have to forced stop this app.

Now I would like your help to solve the problem, why my "System update" is using all of the battery and why it is running all the time, How can I solve the problem without factory reset? I already tried running phone in "safe mode" and "wipe cache partition" which did not help.

Thank you.

How to register/invite a communication partner in Signal on LineageOS?
I used Signal once on CyanogenMod and it didn't make me think during the registration. Now that I want to recreate a secure communication with my previous communication partner on LineageOS (OS reinstallation) I face the following problem after installing Signal from the Google PlayStore:

I can send SMS invitations and receive them. They contain an obfuscated HTTPS link which is opened in the default browser which redirects to https://play.google.com/... from https://signal.org/... and offers to "Open in Play Store App" which redirects to https://play.app.goo.gl/... (a phishing scam? And if not why would anyone choose such a URL?). The problem is that the websites offers to install the app although it already is installed (maybe the web app doesn't have access permissions to that information and always offers to install which would make me think even more).

https://support.signal.org/hc/en-us/articles/219377827 doesn't mention the reception of SMS and doesn't like any information how to proceed with it.

Not matter which unnecessary inacceptable confusion the first two points cause: there's no way to confirm the invitation because everything ends in the request to install an already installed application. Since I was hoping for better support of using the invitation when using Signal as the system-wide SMS application, I cannot deinstall it because I'd loose all my SMS or at least those exchanged after making Signal the system-wide SMS application. This comes very close to malware behaviour (not all criteria is fulfilled, though)...

How to get started using Signal as secure messenger instead of SMS application and how to undo the setup as system-wide SMS application with as few data loss as possible?

I'm using LineageOS 14.1.

APK version downgrade impossible on Rooted Nougat 7.0?
From the title it's weird that i've removed a system app and it's data folder from system and data locations by using this batch :

adb shell rm -r /system/app/apkfolder
adb shell rm -r /data/data/apk.package.name
adb shell rm -r /data/data/apk.package.name

I executed the last command twice to make sure that the folder was deleted entirely, and yes the shell reply was :

C:\Users\User>adb remount
remount succeeded

C:\Users\User>adb shell rm -r /data/data/apk.package.name
rm: /data/data/apk.package.name: No such file or directory
</code>```

Now I've tried to install an older version of the APK V1.0 build 1 (the removed version was 2.0 build 2) by using :

```<code>adb install -r apkfile.apk
</code>```

And this is the response:

```<code>C:\Users\User\Desktop>adb install -r apkfile.apk
adb: failed to install apkfile.apk: Failure [INSTALL_FAILED_VERSION_DOWNGRADE]

Now, I've copied the file to priv-app using :

```<code>adb push apkfile.apk /system/priv-app
adb shell chmod 644 /system/priv-app/apkfile.apk

And this is the response (tried this before with /system/app folder and got the same result) :

And even launching the main activity by calling its launchable activity is not possible:

```<code>adb shell am start -n apk.package.name/apk.package.name.MainActivity

The device SoC is an MTK

The device has an engineer build.

Edditing updater-script
In this thread, #6 post jellopuddingstick said that he could remove the check on updater-script in order to flash a rom which doesnt fit with build.prop .

For example, this is my updater script I found in meta inf/com/google/android:

```<code>assert(getprop("ro.product.device") == "thea" || getprop("ro.build.product") == "thea" ||

Devices without Firmware OTA. Why and how to check?
Sellers often specify on their site if a device support Firmware OTA updates, or not.

Two questions:

If the OS is original android - why wouldn't it support Firmware OTA updates?

After I received a phone - how can I immediately check if it supports Firmware OTA updates, without waiting for the next update?

Thanks!

Examples for phones:

With OTA:

Scroll all the way down and look for this message:

```<code>Pls read me before you make order.

we will open the original box to check the phone and install Multi-language ROM
and Google play store.
Official rom will be prefered.
if custom translation may does not cover all the menus.
Not support OTA update.                    <--<---<------
We may update the ROM, so the OS version may different as the screenshots.

P.S.

In local stores I noticed it mostly about whether the device was bought from an official distributor, or from a parallel distributor.

Use bluetooth call audio as speaker audio with Roger Pen
I have a Roger Pen that is linked to my LG G5 via bluetooth to answer phone calls. I am told that the pen can only answer and end calls via bluetooth, but if I want to play music through my pen, I have to connect it via a audio cable with a micro usb adapter.

This set up to play music is a little daunting, especially with a small cable dangling with my phone. So I was wondering if it is possible to route music through the bluetooth call audio function?

On the profiles for the Roger Pen on bluetooth settings, there is only the Call audio setting enabled. I was wondering if there was an app to override this?

问:
Serial console user belongs to less groups than adb shell
Even though the user is the same uid=2000(shell), still the output of group is very different when run on adb shell (rooted device) than on serial console.
So it seems that through adb shell the user belongs to more groups than when logged in on a serial console.

On other Linux systems it is the opposite - you have more rights when on serial console, since apparently you have direct physical access, but on Android (at least on Oreo) it does not seem logical, since adb can run over Wi-Fi for example.

What is the idea behind such decision?

Can't find where my file is when using adb (it seems to be there)
I will try and keep this brief. I am "working" on trying to get the sidelights on a  custom 10" android display with sidelights (for meeting signage) to work.

I am just starting to try and follow the instructions the manufacturer gave me (pasted all that below). I seem to need a file called  LibledsetJni.so

Anyway! I connect to the panel using adb shell in root. If I am in root and I search like this:

root@rk312x:/ # ls -laR | grep (and either) "libledsetJni.so", or "ledsetJni"

  it comes up with
  -rwxr-xr-x system system   13432 1979-12-31 11:42 libledsetJni.so

WHich makes me think this file is somewhere. However I cant find the path. If I go up from root to system and do the search again, it comes back with nothing. I have been working on this for over a day and I can't find this file anywhere!! Can someone please help?

Thanks

Instructions from manufacturer on getting lights to work.

Controlling LED JNI User Guide There are two ways to import the JNI :
1) Directly use our JNI, copy the Libledset.Jei.so file into libs\armeab, use the below codeand load the lib document. public native void setLedState(int led, int state);static{System.loadLibrary("ledsetJni");} Reminders: In System.loadLibrary(“ledsetJni”) should use ledsetJni and not libledsetJni.so Library document name should be: com.glorystar.ledtest, category name is: MainActivity. The set I/O use setLedState (int led, int state); led is 0 setting red, led = 1 setting green, state= 1 open, state=0close

2) Rewrite the JNI document. Put the reference JNI document copy to the project, note to revise theJava_com_glorystar_ledtest_MainActivity_setLedState in ledset.c . Use your own projectname and category name for exchange, NDK programming should be self- learnt, themethod is on number 1.

No folders showing up when connecting Moto G4 via MTP
I just recently bought a Moto G4 and I'm trying to put files on it, however upon attempting to use the MTP mode, neither my SD card or internal drive show up in the phone's MTP folder.

Moto G4 clearly shows up. However..

There is nothing in that drive. I have switched it between PTP and MTP just to see if it could detect either, but neither showed up at all. Developer settings are enabled, along with adb/root. My phone is using Lineage 14.1's latest nightly.

What do I do?

EDIT: I've discovered that the SD card can show up, so long as it's formatted to be portable. It will not show up if it's formatted for internal.

With the Pixel 2 supporting USB Audio Class 1/2/3, which USB audio devices work? Or *don't* work?
https://productforums.google.com/forum/#!topic/phone-by-google/Yvy0RfOPFfU

Pixel 2 supports audio adapters and headsets that communicate digitally over USB-C as defined by USB Audio Class 1/2/3.  Pixel 2 does not support an analog audio signal over USB-C and subsequently will display an unsupported notification warning when an analog audio device is attached.

Here's the spec documents from USB.org:

http://www.usb.org/developers/docs/devclass_docs/

So it got me thinking, what kinds of USB audio devices are actually supported?

Audio mixers, like this one from Behringer? Or does it only support USB output, not input? I have such a mixer, but I don't have a Pixel 2 to test.

Car stereos, to my knowledge, have never supported any USB Audio Device class. I hope this changes, but all I've seen is support for USB mass storage mode (only old versions of Android), then MTP (only plays formats that the car stereo supports; no FLAC, maybe no AAC), and then AOA v2, which seems to have been abandoned for some reason (Pixel 2 doesn't support it, nor does the Moto X4).

USB headphones: some recommended models are listed on the Google post I linked above. Are there any that you've found not to work?

USB DACs/amps: here's a thread, they seem to be well supported.

Speaker docks: they only support iPhones, don't they? Has any manufacturer chosen to make one for the Pixel 2, or are there any that support a class of USB Audio?


问:
Why won't Android recognize my micro SD card and how can I get it to?
I have an Acer Iconia A1-810 that is running stock Android 4.4.2 and I have a SanDisk Ultra PLUS A1 16 GB microSD card. I am having so much trouble getting the tablet to recognize the card. If I have an SD card that is filled completely with zeroes, then Android should still be able to detect it and have some option to format it, right?

I have tried these things:

Totally wiping the MBR: I slide it into the micro SD slot, it makes the clicking noise for the locking mechanism, and the message I see up in the notification bar is "Removed SD card" (I just inserted it!!!). Going to Settings > Storage, under SD CARD, there is only one item and it is grayed out. The grayed out item says in big letters "Mount SD card" and the smaller text beneath it says "Insert an SD card for mounting". There is no option to format the card.

The micro SD cards's only non-zero bytes are 0x55 and 0xAA at offsets, meaning it has a valid MBR (albeit with no partitions set):  I slide it into the micro SD slot, it makes the clicking noise for the locking mechanism, and this time the message says "Damaged SD card". I pull down the notification panel and see that the smaller text below "Damaged SD card" says "SD card is damaged. Try reformatting it.". I click the notification item. Now in Settings > Storage, there a re four things': a blank bar that would normally show the card's data is divided up into, used space (it says it's calculating), total space (calculating), and finally an item for unmounting the card. Once it is "unmounted", the mount item is white/pressable. I press, but each time the mounting option will fail and the button will go back to being pressable and saying "Mount SD card". Once I leave settings, however, and come back to it,the option looks as it does in #1.

MBR has one unformatted partition set to type 0x0B (FAT32): See #1.

MBR has one partition entry set to 0x0B AND the partition has been formatted with mkfs.vfat: See#1.

What's going on?

Update: Formatting the whole SD card with FAT32 (no MBR) makes the device recognize it, but when I reboot it goes back to the above happening.

How to undo vestiges of themes past
hardware: Samsung Galaxy S8+ (SM-G955U)
software: Android 7.0 (Nougat)

In December, I installed Samsung's "White Winter" theme. Then I installed "For Snowy Porch" in January followed by "winter tree" in February. The problem I'm having is that there are elements of the White Winter theme that remain on the phone even after installing two other themes afterward. Here are the elements that remain and that I now wish to change to something that better matches the theme I currently have installed:

The left and right app shortcuts on the lock screen (the phone and camera). Note that I am not trying to change the apps that are launched by these shortcuts. I am trying to change the appearance. I want to replace the icon.

The background image that appears when the settings menu is pulled up. It is currently set to the background image for the White Winter theme. I would like to change it to something else.

Similarly to #2 , the background image that appears when I bring up the phone app (showing "recents", "contacts", or the number pad). It shows the background image for the White Winter theme, and I would like to change it.

Also on the phone app, when I display contacts and scroll down to contacts just after "frequently contacted", there is a section for contacts that start with symbols. The section is labeled "&". E.g., "#BAL", and "#DATA". The icons that display to the left of those contacts are from the White Winter theme. I'd like to restore them all to the way they were. I could do this one by one, but I was hoping there was a way to just replace the entire icon pack at once.

Thanks!

How to recover lost data after a factory reset in samsung note 3 SM-n900 series?

I was watching this tutorial to recover the data back using testdisk in windows.

How to do a reset my LTE profile? (or fix some type of hardware LTE failure)
My phone, Samsung G920FD aka Galaxy S6 Duo works with band 3 LTE yet lately (two days ago), it sudden stops to work on this band, it simply doesn't connect to it while my other phones connect to band 3 just fine. I tried installing other SIM cards on this phone, and none of them work (yet they work on other phones). The only thing I did was to install a SIM manager on my device to switch between two SIM cards. I don't think this causes a LTE failure. I've tried doing a hard-reset as well as flashing the ROM (to three different versions, my original one, FrankensteinS6, and OFFICIAL LineageOS 14.1). None of which works. Is it possible that my LTE chipset or other hardware broke perminently? Is not, how to fix it?</p>

Prevent Permission Monitor from resetting
The new Permission Monitor keeps resetting the exceptions that I give it.

Often, when I send or receive texts using Next SMS (previously Handcent), the Permission Monitor gives me a notification telling me that Next is using the "Send SMS" permission in the background.

Since this is my chosen SMS app, I'm obviously ok with it sending texts.

The problem is, even though I've told the Permission Monitor repeatedly to add Next to the whitelist, it keeps resetting my preferences and sporadically starts giving me warnings again about the permission usage.

It seems to reset every time Next is updated, but it seems ridiculous to reset the settings associated with an app every time it's updated, even when no new permissions are required.

Is there a way to stop the permission preferences from being reset constantly?

Google contacts background color change
From Dec 2017, I am using my new Android device attached with my old Google id. The contacts got automatically synced. And, works without any issues. But, today I have noticed that, one of the contact's background(default color added automatically) color got changed automatically. I haven't edited contact.(Sometimes editing contact changes color).

For Example: Contact A: contact's background is black previously, now changed to Pink. Contact B: contact's background is green previously, now changed to Dark red.(N.B: Contact A and B have the most number of call logs in my phone)

Why's this happening like this? What's the logic behind it? If it is regular/normal, does this happen in any interval? I haven't noticed this on previous device.

Some apps (SD card ones?) not restored after factory reset of S5. What have I lost? Help!
After a factory reset of my Galaxy S5(same accounts and sim etc), some apps did not restore. I suspect it was the large ones I had moved to the SD card a while back for space reasons (I took my SD card out during the reset and restore process).

Looking in my files>SD card>android>data, there are plenty of apps that did get restored that have files on SD card, but it helped me pinpoint a few that didn't reappear. For example Excel. I then checked the app manager and there aren't there under SD card (though I might be confusing the inbuilt and external SD card).

On Play store>my apps & games, they obviously aren't under 'installed', nor even under 'Library', nor when i search for them individually do the paid versions show as already paid...

I synced my backups on google and Samsung accounts directly before the factory reset

My questions then are:
- Where can i find out what I've lost? ie a list of apps as of yesterday
- Is there any way of restoring apps moved to SD card?
- If not, I might as well wipe the pre-reset data folder on SD-card, right?
- What is likely to have happened?
- Before any future factory resets, should i move everything important back to phone before syncing and resetting

Thank you for your time and expertise!!!

VLC accesses NFS share but cannot play videos
The NFS share (configured as read-only) was added via the 'Local Network' option in the VLC app.

The NFS share's directory and contents are displayed in the VLC app; however, when a video is selected, a "Playback error" results.  Unfortunately, the error message is displayed for a fraction of a second, and is therefore illegible.

The NFS share is accessed via multiple computers, which employ the desktop version of VLC to play videos, so the share is functioning correctly.  When copies of the videos are in local storage, they play without issue.

Why are the videos unplayable?

UPDATE: Audio files contained in the NFS share are able to be played without issue.

Switching between keyboards with Bluetooth keyboard with cmd + space shortcut
I use an Apple Bluetooth Keyboard with External Keyboard Helper Pro as my keyboard of choice on an Android 7.0 Tablet.

I use Gboard when I'm not using the external keyboard.

When the external keyboard is connected, the input method in use can be switched by pressing cmd + space.

But instead of switching between all the installed soft keyboards, it switches between handwriting recognition and External Keyboard Pro.

On the other hand, if I manually switch to Gboard with the keyboard selector icon, the cmd + space shortcut switches between the default Android keyboard and Gboard only.

Is there a way to configure the language switch to choose between External Keyboard Pro and Gboard only?

Or make it switch between all available input methods?

I tried disabling the handwriting recognition input method and now, when External Keyboard Pro is selected, cmd + space does nothing.

I tried disabling the Android Keyboard (AOSP) and it automatically disables Gboard as well.

How do I prevent notifications from certain app from being dismissed?
So, going on the opposite side of the maiority of people: there are apps whose notifications I don't want to be able do dismiss.

For example, I use Samsung Health and Daylio to keep track of my sleeping habits and my moods and activities, and they both give me notifications for when to go open the app to record something.

As a reflex of my body, what happens is, I open the notification bar and click the Clear All on instinct, resulting in me forgetting to open it later to make that record.

Reminder apps are simply not working with me.

Is there any way I can configure notifications for being undismissable? I wanted them to clear only if I clicked them, or if I did the thing it was expecting me to do.

I had to replace the screen on my Lg V20 and broke the front and wide angle camera while doing so. When I ordered replacements and replaced them, the wide angle worked, but now the front camera crashes both the LG camera and Google Camera port. When I scanned it with a Camera2 API scanner, it showed up, but I noticed it said HARDWARE_LEVEL_LIMITED next to hardware level. Is there anything I can do to get this working? </p>

URLs not opening in native app
Samsung Galaxy S7, stock Android 7.0

I have the Meetup app installed.

If I go to App settings → Meetup → Set as default → App links:

Go to supported URLs is set to "Via this app".

Supported web addresses lists meet.meetup.com among others.

In Gmail, I click a link that starts with https://meet.meetup.com/wf/..., and... it opens in Firefox, not in the Meetup app.

How do I get it to open in the correct app?  It's super frustrating that my settings are being ignored.

Then, after it loads in Firefox, I have an Android icon in the address bar, indicating that it can open in a native app:

I click that icon and... it opens a new tab in Firefox.

I tried the Open Link in App app, and the link... still opens in Firefox, without asking me which app I prefer.

I tried the Open Link With... app, and allowed Usage Tracking.  I Share link and send it to that app, and it gives me the option of whether to open in Meetup or Firefox.  I select "Meetup / Always", it says

and then... opens in Firefox.

Tasker - overlay not working
I own a rooted Xiaomi Redmi Note 3 smartphone and  experience phantom touches in a horizontal rectangular zone on my touchscreen.

To fix this, I am trying to create a transparent blocking overlay scene via tasker, but am unable to do it. I can create dialog and activity scenes and they display properly if I create an action to show the scene.

However, if I try to make any overlay scene, nothing happens at all when I click the play button to display the scene. I do see a green dot, but nothing happens even after clicking the play button repeatedly. Could someone help me with this or suggest me another method to block touch input from specific region?

If I click play after the green dot appears, I get a red dot with this message-

```<code>23.30.36/TD data: haveStatic: Passive true
23.30.36/TD getStatic: Passive load true
23.30.36/TD getStatic: Passive load: true
23.30.36/E doShowScene: scene already visible: Nzj
</code>```

As an example, even if I take this simple scene, overlay doesn't work.

```<code>Scene: Nzj

Edit: It's working now. Just add to give tasker the permission to open popup windows. I don't know why it did not request for the permission itself.

All Notification Tray Items Dismissed When Opening App
So on my iPhone the notification tray items disappear when I have viewed the message inside the actual application.  Windows Phone works the same way.  While all notification tray items for that app disappear when I open that application.  I do not like that all my notifications have disappeared.  Is there a setting for this maybe?

Right now I receive maybe 10 gmail or messenger notification emails and it dismisses all of the notifications as if I have read them all when I open the Gmail application from the home screen directly.  If I click on the notifications separately everything is fine.  This seems like very bizarre behavior to me.  I just can't open the app on my phone.

The hilarious thing is if I read one of the Gmail/Messenger notifications on my desktop it updates the notification properly and only dismisses one of the 10 notifications.

Edit: Ideally I am looking for a way to get this to prevent all notifications from dismissing from my mail application for sure.

Boot loop, adoptable storage, did factory reset but screwed up by putting sd card in again
My device is a LG H440n. I did use adoptable storage aka external SD card as internal storage. I had quite a few games on my phone. Yesterday it has gone into boot loop, I can't rember what I did unfornuately.

When I see the graphical UI, it says that the process system has stopped wirking and restarts immediately almost every time. Yesterday I managed to get in the menu and do the factory reset and the device was ok again. Then I got cocky, put in SD card again and now it's in boot loop again. Today It won't let me.

I cant get to the factory reset through pushing buttons on boot, either Im doing it wrong, what I doubt or the buttons are not reacting.

I tried adb then:

```<code>#!/bin/bash
echo " "
echo "Wating for device..."
adb start-server
adb wait-for-device
echo "fu "
adb -d shell stop
adb get-state
adb status-window
</code>```

Tried adb again:

```<code>#!/bin/bash

adb wait-for-device

echo $(adb shell getprop sys.boot_completed)
A=$(adb shell getprop sys.boot_completed | tr -d '\r')

while [ "$A" != "1" ]; do
        sleep 1

        A=$(adb shell getprop sys.boot_completed | tr -d '\r')
        echo $(adb shell getprop sys.boot_completed)
done

echo "something"

I also used watch with adb devices

```<code>watch -n 2 "adb devices >> testt"

Nothing showed up anywhere.

How to reset the touch screen properties, as seen by Android?
I have a Samsung Galaxy Note 4 which was started to be buggy and I decided to install a new ROM (Lineage 14.1). I first checked the version of TWRP and saw that there was a new version (I had 3.0, 3.2 is available). I flashed it through the TWRP app but I could not boot to TWRP.

I had a backup of my previous TWRP (and also of "boot") so I wanted to restore it.

I realized that the "touch" area is a different size that the physical screen and that I need to offset my touch by 1-2 cm up in order to hit the right button.

After the recovery, I had TWRP 3.0 again and managed (after much mis-clicking) to install Lineage 14.1 and Gapps.

My problem is that the touch area is still offset vs. the screen.

While the device booted into Lineage, I cannot realistically use it because of this shift.

I believe that flashing the wrong TWRP set some information about the physical size of the screen and its relationship to the touch functionality. Reflashing 3.0 did not fix it.

I am quite desperate since the phone is formally working but not usable. How can I reset its perception of the screen size?  It now looks like Android thinks I have a screen smaller than in reality (and adapts the touch, see the video I added below)

EDIT: I made a video with the help of the Multitouch app to show how the scaling is off: https://mega.nz/#!84pDnIZI!XZPnP-9YDKON93aPzDZZRPjXR-u7iGn_mnvN3ei8qN4 (sorry for the blur in the middle, I was juggling with two phones)

EDIT 2: The pen of the Note 4 works correctly - the place I touch on the screen is correctly recognized by Android. In the Multitouch application and video above, the tip of the pen is in the center of the green dot everywhere on the screen.

Phone not finding ANY wifi networks
Suddenly my phone is failing to recognise any wifi networks.

It just keeps on searching and searching but nothing appears in the list.

The only thing I have done recently was I had it in airline more on Friday (intentionally) but switched it back.
TBH, I am not sure if the wifi worked after that or not.

The phone is a Nexus 6 with android version 7.1.1.

Obviously, I wish to avoid a factory reset if I can!
I can manage with the mobile network as I have an effectively unlimited plan but that will not help when I travel abroad.

Edit:
It seems that I can't use my phone as a hotpoint either. None of my devices recognise it.
Must have broken something when I dropped it a couple of days ago. :(

I guess factory reset is the next thing to try.

How to rotate touch input on Android?
I've got an ir touch frame which is properly detected on android, but its coordinates are not translated properly on the system - the input is rotated by 90 degrees and the coordinates are interpolated accordingly.

I've tried to force rotate the screen by 90 degrees and set the touch.orientationAware = 0 in the idc file for the device. The coordinates are better (moving finger in x axis actually moves the pointer in x axis) but the values are incorrect and it covers only part of the screen.

In here: https://stackoverflow.com/questions/21564830/android-touchscreen-position-off I read about someone's attempt to change the output.x value, however it does not work for me at all. Changing this value has no effect whatsoever on the values reported.

How to record audio on a smartphone from a mixer

Chrome INSTALL_FAILED_ALREADY_EXISTS but I am certain it doesn't
Hi all I am trying to side load a chrome apk via ADB but it is giving me the INSTALL_FAILED_ALREADY_EXISTS error. I have verified via exhaustive searches of the packages and even the root that no file/apk/package exists that even has the word chrome in its title anywhere. Play Store also confirmed it is not installed. It will download the file but gives "already installed" error when it tried to load it.  Cleared all caches/data and same.  Also tried direct downloading the apk and installing that way but it just crashes.

The only thing I can think of is there is some other "flag" or registry somewhere that is telling it that it is still installed when it isn't?  Where might that be? Or a hidden file perhaps?

FYI this is Android 4.4.2 older machine but needed.

All of the devices run same Android 7.1.1 version (build number N4F26T) and supposedly same security patch. Supposedly because Android patches won’t apply to rooted devices, because system is unable to verify checksums or something.

After some time (~ 6 months), devices started to behave strange, i.e., not able to receive/send network requests, automatically disconnect from known Wi-Fi access point. Some devices event stuck in boot loop after rebooting the device using the built-in “reboot” command.

We think that this is some kind of hardware issue, because Pixel Cs weren’t supposed to operate this way besides internetz are full of complaints about Pixel C, or a software bug, which with our operation mode (rooted + device owner) has lead to this state.

Did anyone come across to this kind of issue with the tablet?

How to lower the minimum volume? (Nougat 7.1.2 through LineageOS 14.1)
The minimum volume level available for alarm and ring settings is visually twice as much on the control in the settings as what is available for media and is just way too loud.

I am not looking to add more steps between the available volume levels; just to lower the minimum for alarm and ring.

Phone is rooted and has xposed as well, though I didn't find a relevant module. Strong preference for an open-source solution, as I won't be installing some random app with excessive permissions.

Phone Keeps Going to Sleep
My phone keeps going to sleep within a minute or so despite the fact that it is set to not go to sleep for 10 minutes. Why is it doing this? This is an Asus ZenFone Live V running Android 7.1.1.

To be more clear, the screen goes black and locks shortly thereafter in about a minute. I'm not sure this is technically sleep mode, but it is sure annoying to have to unlock every time something steals your attention for a minute.

spy / invisible file occupying 4gb+ space in internal storage
I am running Android 6 Marshmallow on Sony Xperia z3.
I use my memory card second partition to link most of my apps and increase my space. (app2 SD / link2sd app)
some of my folders I link manually using a folder mount program. from internal memory to memory card first or main partition. for purpose of my testing I unmounted or delink all tgese linked folders.

so my internal memory shows as just 1.2 gig free from some 12 gig internal memory. matter of fact currently space occupied shows only has 4.5 gig . using any File Explorer. I am using this file explorer in root mode which means I am able to see all invisible or hidden folders..

in spite of that I am not able to account for the missing 4 + GB or space what is occupying this... there is some process That seems to be creating a totally invisible file which even I cannot see as root..

how to identify this kind of files and go ahead and delete them. if only 1.2 GB is free it means around 10 GB is occupied but in the attached picture only 4.8 GB are occupied. how do you account for the discrepancy ?

Whatsapp messages dissappearing
On Samsung Galaxy A5 Whatsapp most of the chats are dissappearing by itself. My mother is using this phone and its backs-up to Google Drive on a daily basis. I checked and can confirm that the messages are indeed missing not archived.

This has happened a few times and except the last one I was able to recover the messages by reinstalling and then renaming the second to last back-up file in WhatsApp/Databasefolder to msgstore.db.crypt12. However, it seems that Google Drive back-ups have precedence over local back-ups and local back-ups are disregarded upon reinstall.

Is it possible somehow to recover these missing messages and have them displayed together with recent messages (judging by the size of the back-up the messages seem to be included)?

Are there apps or Windows programs capable of selecting a particular
back-up and loading it?

What can be done to prevent this from
happening again?

HTC One M9 Boot Loop
I have a HTC One M9 Factory unlocked, never rooted, OEM Software, OEM ALL, last night I was using it and it froze.

-I've tried wiping the cache.
-I've tried factory reset.

But it keeps going in the loop. I've tried unlocking the bootloader but all the tutorials i've seen are telling me to enable it in developer options (wich I can't reach).

Any suggestions?

LG V10 Mysterious Shutdown Loop
My phone is stuck in the strangest bootloop I've ever encountered. Last night my phone dropped to 0% battery, so I charged it on up and restarted it. I didn't look at it for a while but when I did it notified me of the phone being updated.

Weird, no updates in the pipeline, when I go to check it says I haven't downloaded a new one in months. Then my phone starts restarting. A couple second freeze, and then it's starting back up. Boots all the way up, then my background apps start up. Minute later, phone's restarting again. The phone keeps this up all night, and into the next morning, varying in the amount of time between boots and crashes

Okay, boot in safe mode, no difference. Clear cache partition, no difference. Factory reset via UI, no difference. Factory reset from boot menu, no difference. Put it in the fridge for 30 minutes, no difference. Wanna hear the weird part?

I decided to discharge the battery all the way, and charge it all the way back up. Might as well, right? Unfortunately at some point my phone decided to start shutting down and staying off, instead of restarting. Shit, well I guess I'll just have to keep starting it up. So I throw on a muted repeating youtube playlist, turned the screen brightness up, and it just keeps going... It plays the videos happily without crashing. When you leave youtube it eventually crashes.

Seems to me like a piece of software in the main OS that starts late in the boot cycle which crashes things and doesn't get factory reset (and youtube stops it from starting?).

So, is there anything I can try beyond flashing the original firmware?

How to show a "large text" SMS preview? (e.g. for confirmation code)
Some online services send you a SMS with a confirmation code (e.g. when requesting a new password). When sliding the notification window (from up to down) in some cases I can see that the actual code is the only information shown (and it's very large), and the complete SMS is shown only if you tap on the notification.

Initially I thought it was simply a result of putting the code as the first token of the SMS body (like "12345 is your code"), but I tried sending an SMS to myself and it seems that is not enough.

Is there some SMS setting that I can use?

My device is Huawei Honor 8 and my OS is Android 7.0 (EMUI 5.0.1)

How to Restore notepad.db in Huawei P7 without factory reset
kindly advise the following.

I have 2 huawei p7 phones, but only 1 sim card(used by the main phone ), and need transfer all the Notepad files to new phone.

The Main one :
although no problem access to internet, but unable to download any apps from Google Playstore, due to certain part of its mobile data reception ability got affected after the phone suffered too many times of hard hit previously.

Its android Beam NFC function also not working.

The secondary(new) one :
ready to replace the main phone, can download apps no problem.
But there are existing notes and other photo files in it.

.
I have backed up the notepad in the Main phone using the Backup function in huawei p7. The backup file is a zip file.
.
So my dilemma now is :
- How to Restore notepad.db in the new Huawei P7 above, without factory reset ?

I am trying to restore all the Notepad from the Main phone into the Secondary new phone, without affecting the existing notepad files in the new phone.

Is there anyway to copy the backup file Notepad.db to a path in the new huawei p7 in order to let the note files restored automatically ?

I only have these 2 mobile phones for any file transfer. No pc or laptop.

Thanks in advance.

How to stop apps from asking permission about learning contacts?
I've been getting an overlay notification on many apps (Textra, Dropbox, Instagram, others) whenever I try to exit out of it (usually hitting the back button). The notification text is:

Did you know?

We can learn your contacts and give you the choice to quickly contact your friends. We just need your permission first

Never |  Maybe Later | Cool!

[Edit - screenshot: https://prnt.sc/iklfbt ]

I hit "Never" every single time, but apparently the word "never" has lost something in translation since it comes up repeatedly.

I've searched Google and found no reference to this message.

How do I get it to stop?
