Android Auto: "<app name> doesn't seem to be working now"
When trying to run the application from the Android Auto car screen, from time to time, I'm getting the info:

app name doesn't seem to be working now

For example:

Spotify doesn't seem to be working now

VRadio doesn't seem to be working now

etc. It basically happens for each app.

Versions:

Android: 12 SKQ1.210908.001

Android Auto: 8.7.630264-release

Running application from the mobile helps in the most cases, but doesn't help in general.

Any ideas how to solve it?

How can I make my phone prefer my mobile network (LTE) over WiFi?
I have a phone running Android One 12. Preferably without root access - is there a way that I can make it prefer my mobile network over WiFi? This is because I'll be traveling on a ferry and want it to use the much cheaper mobile network over the exorbitant prices charged by the ferry's operator. This is mainly for when I get back in range of cellular - I'll manually switch at the beginning of the journey.</p>

How to avoid/disable Android removing permissions and data from unused apps?
The most annoying thing I know is the feature where Android removing permissions and data from unused apps. OK, fine they deem it a security thing, but I want it off. So annoying to have spent ten minutes inputting all the data for some app, including credit cards and online verification, just to be greeted with a whole lot of nothing six months later because Android thought it would be a good idea.

I do not need the space it frees up, so I want to disable this functionality. How?

Scheduled messages and icon widget displayed on home screen
I am running Android 12 on a Realme 8 5G phone.

When using the SMS application, it is possible to schedule a text message (for instance, it might be night, and you don't want to wake the receiver up, so you schedule it to be sent automatically during the day).

However, it may be, that the phone powers off, and, then, the user is asked whether to send the message when powered on or it is sent automatically if not too late (as configured in the global app or per message settings).

However, you can do better: on the lock screen you can display an icon saying that a message is to be sent, so, that the user, may not disconnect the phone from the charger, play a video that sucks out the battery, place the phone on the sofa, and then the message is sent late. Instead, if an icon is placed on the home screen, the user will not view the video, and the phone will stay connected to the battery charger, (and, in the morning, when the time to send the message comes, the message will be sent, unless there is a power outage).

Next to the icon there should be a queue, scrollable horizontally like in the ViewPager2 Android Java class functionality, but for this purpose, where you can also view the exact times where the message is pending (and, decide, this way, whether to disconnect the phone from the plug and view a bit of video far away from the plug in the wall, or not).

In this case, if the phone has an LED, you may want to leave it on during charging or change is color (and the screen could be blanked instead of turned off with an icon displayed, but this could be configured in the app (which would need to be given a special Android permission to do this).

Is this functionality available in Android?

Thanks.

Newbie to android needs help transferring texts from iPhone to new Pixel 7 after setup
all. My only smartphone experience is with an old iPhone 6S someone gave me. My 92yo MIL's landlline went down and won't be back up for a while (we're in the country--things take forever), so we decided to get a cell phone for her, and one for my husband while we were at it. We got Pixel 7s because that's what came free with the two new lines. Then we decided I would get one of the Pixel 7s and give her my old iPhone because the iPhone is less complicated to use. Android has been a huge learning curve for us after using iPhone for so long.

Our carrier is T-Mobile, and the phones were set up at the store. Needless to say, some data was not transferred to the Pixel 7 from the iPhone and the setup process is now "finished". How can I transfer text messages from iPhone to Pixel 7 at this point? I would like to get all my data off the iPhone so I can clean it up and give it to my MIL. She lives along and I don't like her being without a phone.

I may be a newbie to Android, but I have done some computer programming (enough to be dangerous) and capable of following directions and not (too) afraid to do so.

Please don't tell me to do a factory reset. I have spent a fair amount of time downloading apps and making sure I can log into them again.

Thanks in advance, everyone, for your assistance.

问:
adb push/pull as root
adb pull and adb push can be used to transfer files from and to the device via the ADB connection.

However, even on a rooted device, these commands seem to operate with user permissions. I can access anything on /sdcard, but when I try to push to, say, /data, the operation fails due to lack of permissions.

Of course, I can push the file to a different location, then adb shell into the device, run su to become root, and then copy the file to its final destination – but that is a kludgy workaround, not a real solution.

Also, I can install an SSH server on the device which runs as root and use SSH to copy the files over, but I am wondering if ADB offers something similar natively.

Is there any way I can get adb push/adb pull to operate with root privileges on the device?

Is there a way to root Anbox?
I use Anbox for development, and at times I need to carry out privileged operations on the system – mostly copying or modifying files outside of /sdcard.

I can adb shell into the system and run su to get a root shell. However, apps cannot run the su binary.

My primary use case up to now is to run an SSH server on Anbox, which can be used for privileged shell and file transfer operations if the su binary is specified as the login shell. However, this currently fails as the app user lacks the privilege to run su.

Do the usual ways to root an Android device (such as Magisk) work on Anbox?

If not, how can I control which apps (i.e. which Linux user accounts) are allowed to run su?

As for security concerns – the Anbox setup in question is purely for development. It holds no sensitive data (worst someone could do is turn Anbox into a zombie to attack other machines on my network, but there are easier ways to do that) and I run only FOSS software on it (lowering the likelihood of installing a malicious app in the belief that it is a legit one). Also, all network communication by Anbox goes through a NAT layer on the host, i.e. any open network ports on Anbox are not normally reachable from outside the host machine. Hence security standards are somewhat lower than for, say, rooting my phone – I don’t necessarily need e.g. a user prompt before an app is granted root access.

WhatsApp crashes after restoring messages
My phone is a Moto G7 with an adopted 64 GB card. My WhatsApp constantly shows a message about something went wrong with your chat history, and I mean constantly, almost daily.

I do the trick of restoring and stopping the process when it reaches 35% and it worked fine...until now.  After restoring, it immediately shows the same message again.  Sometimes it complains about not having enough space. The restoration creates a lot of zero bytes video files. If I delete them, the process continues.

I have deleted the data, uninstalled it, and reinstalled it. Nothing works. If I reinstall and stop the process, it asks for my name, shows the initializing, and crashes again. If I let the restore run until the end, I get the well-known message about not being able to complete it.

The only way to have it running again is to omit the restoration which it's obvious what I don't want since like most of us, I have important messages.

I've read most questions about the problem but have been unable to find an answer, as AFAIK this bug has existed since forever on WhatsApp.

Any ideas on how to restore my messages?

Edit: After omitting the restoration, I put my phone on plane mode so it does not receive any pending messages

问:
Nokia G10 Android kernel source code availability and GPL request procedure
I'm thinking about doing a LineageOS port for the Nokia G10. One part of doing the port is getting access to the Android kernel sources. Since the Android kernel is GPL 2, HMD - the company behind the Nokia phone - is obligated to release it. So far I have not found the sources anywhere.

Because I have not found the sources, I have contacted the support. The first contact with the first level support by email showed that this topic is unknown. I have looked into my phone again and found in the device's "about section" the statement:

This product includes open source software that is included under the GPL ... Please send a written request to:
Source Code Requests, Legal Department, HMD Global Oy, Bertel Jungin aukio, 02600 Espoo, Finland. ...

Has someone experience with the process? Providing a postal address seems to me an indication that any request is actually unwanted. It seems that the goal is to make it as hard as possible when a link would be sufficient.

The GPL states:

The source must be provided as machine-readable source code.

What should I expect here? E.g. would it be still acceptable to receive a CD (for which I have no reader anymore) or some magnetic tape (which I also cannot read)?

What quality can I expect from the source code? The GPL states:

complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable.

Will it be an accessible compatible format or what are the options to obfuscate it? Or is my concern not reasoned?

How much can it cost? The GPL states:

for a charge no more than your cost of physically performing source distribution

I would assume it is the physical media what is meant hear. Can it be more? What are the limits?

The GPL does not define a maximum expected time until the request must be fulfilled. Will I have to wait for months?

What other institutions could assist me, if my request is ignored?


问:
Single notification settings for the whole app on android 13
Sorry for this stupid question, but I'm struggling to do such a basic thing as to configure notifications settings for incoming SMS on Pixel 5 (Android 13).

I want to silence all notifications for all senders from the Messages app (e.g. I want to continue receiving notifications in the notifications shade, but without sound or vibration).

When I open Messages Settings -> Notifications I have following options:

All Messages notifications - completely disables notifications, including the shade

Conversations section - allows to configure each sender individually

All 'Default settings' notifications - completely disables notifications, including the shade

Incoming messages - once I configured this to 'Silent' it worked for a while, but then android started creating individual setting for some senders with 'Default' settings (sound on)

settings for some senders - allows to configure each sender individually

Settings -> Default notification sound - this also affects other applications.

Can I turn off 'per-sender' settings and configure it once for the whole app (for any sender)?

Now I have to click through each incoming number, and configure it individually. And for the new numbers android sometimes creates new sections, with sound switched on, so I have to configure them again.

Most answers I find online describe how to do the opposite.

How do I flash a custom kernel on Pixel 7
I built a custom kernel for my Pixel 7, to include the NFS kernel module. I'm struggling to flash this to my phone and get it loading.

After I flash this to my phone, the Google text appears, but not the G animation that follows. It dies with the following message:

Android Recovery

google/panther/panther

13/TQ1A.221205.011/9244662

user/release-keys

Use volume up/down and power.

Cannot load Android system. Your data may be corrupt. If you continue to get this message, you may need to perform a factory data reset and erase all user data stored on the device.

[x] Try again

[ ] Factory data reset

To recover from this I flashed the stock panther-tq1a.221205.011.zip/image-panther-tq1a.221205.011/boot.img back.

The only thing I could find is where the boot log /sys/fs/pstore/console-ramoops-0 has the message:

```<code>[  11.517099] [E] [DPM] check header failed
[  11.517105] [E] [LNXDBG] vendor combined_checksum must be 0x62352e30 but 0x620d2e30
</code>```

I thought this was related to Android Verified Boot 2.0. To test this out, I tried to flash the stock image and stock vbmeta.img, with AVBv2 disabled:

```<code>$ fastboot flash --disable-verification vbmeta vbmeta.img
</code>```

This also surprisingly results in the above boot loop. To recover I have to flash vbmeta.img without this flag:

```<code>$ fastboot flash vbmeta vbmeta.img
</code>```

I tried to patch vbmeta.img flags at offset 0x7B to be 3 (aka AVB_VBMETA_IMAGE_FLAGS_HASHTREE_DISABLED | AVB_VBMETA_IMAGE_FLAGS_VERIFICATION_DISABLED). I flashed this, and the same boot loop occured.

My phone is rooted with Magisk.

Weird black spots when taking pictures with the camera
I recently noticed there are black spots on the camera preview screen as well as the final picture saved by the camera. When I zoom in the spopts are not static, that is, it is possible to zoom to the centre of the screen while in camera preview mode, and the spots will move eventually move out of view.

This is a picture taken using this camera:

This is what it looks like when this picture is zoomed in (zooming in on the top spot above; each spot looks different):

The spot also appears on the camera preview screen:

However, in the camera preview screen this spot is not at a fixed place and moves when zoomed out. Here is an example of what happens to the top spot when zooming in at the centre of the screen:

These spots are also seen when using a different camera app (Open Camera). The screenshots above were from the default camera app. The phone is Samsung Galaxy S7 (SM-G930K) with Android 8.0. The screen looks normal otherwise. This problem is not seen on the front camera.

What is going on here? Is this a problem with the camera hardware? Is this just a loose wire or something, or is this fixable?


问:
How do I prevent my photos from turning sideways, when taking photos by pointing my phone towards the floor?
I have a Galaxy S10 phone. I'm in visual art school. I will have to take hundreds of photos of my artwork, by placing the artwork on the floor, and pointing the camera towards the floor to take the photo of it.

Often, when I take photos with my camera pointing towards the floor [ie, parallel to the floor], my photos end up being turned sideways (or even upside-down), even though when I take the photo in the default Samsung Camera app, the top of my artwork is at the top edge of my phone, and the bottom of my artwork is at the bottom edge of my phone.

(I don't want to have to manually rotate each of my photos after uploading them to a laptop and reviewing each photo one-by-one. At the end of this semester, I'll have more than 1000 photos that I'll have to take, and I don't want to have to check them all and rotate them all.)

(I am okay to use a different Camera app, as long as that app gives a lot of control over how the photo looks. My big pet peeve is that the Samsung Camera app tries to "beautify" my artwork, which really ruins the actual colours on the artwork itself! I am also okay if there is a simple command-line program that I can apply to every .jpeg file in a folder; from this post, I get the idea that there is some EXIF orientation data on each photo, and that removing this data might solve my problem.. but I don't fully understand the information in that post. )

TalkBack and speech-dumb users
I am a speech-dumb person. I can read and write to understand, but when spoken to, I have difficulty grocking and grasping what is said.

My ambition, at the moment, is to be able to use voice input and output on my Android device to control it (and follow stories and stuff as spoken to me).

To see where we're at, I've tried to use TalkBack. The interface, brings me to this:

However, here, with my disability, I am already at loss.

In order to overcome my difficulty in using the phone without looking at it, I would need to be able to interrupt TakBack, while reading the text, to ask questions about the text (you could ask me, why not just read the text. No, I am trying to use the phone without looking at it, with my disability, engaging by reading and talking.

So, here is what I would like to do. I would like, something like Google Assistant, to work over TalkBack, so that I can query the text as it is read. For example, consider the following interaction (where, me, as a speech-dumb user, can interact):

TalkBack: TakBack is a screen reader.

Me: What is TakBack?

TalkBack: A screen reader.

Me: What is it?

TalkBack: A screen reader.

Me: Ok.

TakBack: Continue?

Me: Yes.

TalkBack: TakBack is a screen reader for situations or people who have difficulty seeing the screen.

Me: What people?

TakBack: who have difficulty seeing the screen

Me: the what?

TalkBack: the screen

Me: what about the screen?

TalkBack: TalkBack, is a screen reader, for people who have difficulty seeing the screen.

(Notice how TakBack here would have also inserted the commas).

Me: Continue

TakBack: It gives you spoken feedback so that you can use your device without looking at the screen.

Me: So that you can do what?

TakBack: So that you can use your device without looking at the screen.

Me: How does it do this?

TakBack: By giving spoken feedback.

Me: Ok

TalkBack: Continue

Me: Yes

TakBack: You can turn TakBack on or off by holding both volume keys for several seconds.

Me: on or off

TakBack: by holding both volume keys for several seconds

Me: in each case?

TakBack: yes.

Me: continue

TakBack: when TakBack is on, the focused item on the screen is spoken or loud

Me: what is spoken out loud?

TakBack: the focused item on the screen

Me: when?

TakBack: when TakBack is on

Me: continue

TalkBack: swiping right will move to the next item, and swiping left will move to the previous item

Me: swiping right will do what?

TakBack: move to the next item

Me: and swiping left

TakBack: move to the previous item

Me: which item

TakBack: the previous item

Me: moving left will do what?

TakBack: move to the previous item

Me: ok

TalkBack: Swipe right now to find the next button.

Me: ok

(user swipes right).

So, how come Android does not yet support interactions for speech-dumb users?

Is there a way Android currently supports this?

Thanks.

Note: I would like to contact the Google accessibility support team about this, via this link:

Google accessibility support page

However, I can only type 5000 characters.

This means, that, I cannot get help from Google because I cannot include the whole text in my post.

Unable to connect to network (cell), new sim card, networks are visible in manual selection list
I have a blackberry key2.  It is supposedly compatible with tmobile, the phone states its volte provisioned.  I'm using Mint Mobile, with their tmobile-network sim card.  For a few months, I've had intermittent service loss, about a week ago it went out completely.  Mint sent me a new sim card to attempt to alleviate the issue.  This did not help and neither did an additional support chat (resetting network settings, apn settings, sim in and out, reboot phone, airplane mode).

I dialed *#*#46368676#*#* and switched my network modes around and that did not seem to do anything either.  I also attempted to power-cycle the cell-radio as well as disabling it and then rebooting the phone.

I am able to see all near-by networks (tmobile, att, verizon, firstnet, mint) and choose any of them from the manual selection list in the cellular network settings, but my phone is unable to actually connect to the networks.

I tried using two different APN setups, the default one on mint's FAQ, and a slightly different one given to me by a support agent (changing MNC to 240,MVNO to "GID" and MVNO value to "756d")

The phone, immediately upon booting up, will flash signal bars and the "emergency calls only" message at the top of the screen.  The message promptly disappears and my signal bars empty.

While I obviously suspect that my phone is at fault, I struggle to understand how it is able to recognize the various networks available, but is still unable to connect.

Is my phone likely borked? Is the sim improperly configured? What's the deal and how can I figure it out without talking to Mint for hours on the phone?

Complete Delete App
TLDR; need to figure out why an app I want to delete is still on my phone (attempting to troubleshoot bug in Snapchat). I can confirm it's not being deleted when I reinstall, because there is NO download or install time.

Long version: Snapchat has been having this bug in my phone where for some reason it's picking up some sort of input or something, I have no idea what. But the effect for me is constant vibrate functions every few seconds or less, making the app very difficult too use (exclusively happens on Snapchat) . I am trying to uninstall and reinstall it as last ditch attempt, as I've even waited for the last update and still no correction. When I uninstall it, everything I see says the app is gone. But I know that it cannot be actually being removed from my device and replaced with a potential bug-free copy of the app because when it downloads, there is practically 0 time prior to it being completely downloaded and installed again. For reference an app of about 50 MGB takes about a minute or so to download.

Any ideas? Just leave the app uninstalled for a few days or weeks maybe? Or is there a hard dump or something that can purge the data manually?

FYI to all, the issue is with the NFC. Somehow, and this is an entirely different problem that asks more questions then it answers, Snapchat is accessing the phones NFC. And the NFC was registering the credit card I keep in the wallet of my phone case. How Snapchat can access the NFC at all, since it's (according to setting) not permitted to access it in anyway, nor is it even asking to access it, I have no idea.

How to disable power button turning on flashlight while screen off in Android?
I have a galaxy S20+, and multiple times per day, when I pick up my phone or pull it out of my pocket and turn the screen on, the flashlight comes on too. It's very annoying.

The flashlight is supposed to turn on if the screen is off and you hold the power button. But often it happens immediately when tapping quickly to turn on the screen, instead of waiting for holding the button.

I don't know why or how this happens. If I try to make it happen, I can't. When I try to replicate the problem, the flashlight won't turn on unless I explicitly turn off the screen and then hold the power button for a second or so, like it's supposed to. The problem just happens when I don't want it to and I can't figure out how to fix.

Half the day my flashlight is on without me realizing, because it happens so much. When I'm at the gym I will often see the flashlight on through my pocket. It's so annoying. Often it shines into my eyes and hurts.

I've looked through all the system settings intensely many times. I can't find any setting. Nothing in the side key has any effect.

I disabled Automate and Button Mapper, but still it happens, so it's not caused by those apps.

I looked through Firefds Kit and Gravity Box, but no setting is there. After months being annoyed by this and unable to solve, I'm coming here in hopes someone can help.

Button Mapper can remap my volume key to do the same thing, so I really just want to fully disable the power key from turning on flashlight while screen off, to solve the problem.

How can I do that? I'm rooted and willing to try anything.

--

Update I found out that it happens only when the phone has been sitting or in my pocket and is picked up and try to turn the screen on at the same time, and it turns on the flashlight. Haven't figured out how to solve it yet.

Extremely Low Volume with Bluetooth Headphones
Currently, when I connect my bluetooth headpones to my phone, the volume is extremely low, even when the volume is set to the maximum level.

For reference, I am using the following:

Bose QC 35 II headphones

Samsung Galaxy S22 Ultra

The sound issues seems to be present in audio apps (i.e., Spotify, Audible, etc.). Audio during phone calls does not seem to be affected. Initially, I thought that it was something wrong with the headphones. However, when I connect another set of bluetooth headphones (a pair of Westone earbuds with the bluetooth cable), the same issue is present. I have also connected the Bose headphones to my wife's phone (same model) and the issue is not present. I have also connected the Bose headphones to two different laptops and, again, the issue is not present. This leads me to believe the issue is with my phone.

The question is whether or not there is some setting that has been altered to cause this issue. I am aware of the "Disable absolute volume" setting that is mentioned in various blog posts. This setting is currently enabled but seems to have no affect on this issue.

I figured I would ask here before performing a system reset to see if that helps in any way (which is kind of a pain).

Why is my chrome password manager and other apps take 2+ minutes to open?
Galaxy S20 5G

This started happening a few months ago. Not sure if it was an android update or not.

When I try to open password manager in chrome it spins and I have to wait 2+ mins- it eventually does open.

I've noticed this with other apps like youtube as well.

I don't think my phone is under load.

Could it have been a recent update? What is the best way to troubleshoot this kind of thing? My phone isn't crashing, while it spins my pod cast app continues to play audio without hiccups so I don't think its the OS lagging.

Its like it just wants to wait several minutes before loading some apps.

How to make voice recognition keep steady when traveling?
My Android 10 phone's voice recognition for English works extremely well, but when I travel to India it switches to expect an Indian accent, and I can barely get it to take my dictation that way, even though I can adapt to speak the local accent some of the time.

Can we tweak some settings to avoid this change in the underlying machine learning model so that it keeps interpreting my English dictation as either UK or US accents of English, thus retaining its existing, pre-travel, levels of accuracy?

I really rely on voice dictation quite a lot.

When referring to voice recognition, I primarily mean the voice typing feature available through the Google Keyboard's microphone icon, but I suspect that the same underlying components also handle the "Hello Google" stuff.

When I go outside of India, it clearly does revert back to expecting US or UK accents again, as if over-adapting to the geography rather than remaining loyal to the user that's already using it.

Actually, at least one person native to India who speaks the Indian accent and dialect of English has mentioned the same issue to me, which they only experience in reverse ― voice recognition accuracy plummets for them when they travel to other English-speaking countries.

Why does Android Auto keep losing Waze
I am using Samsung Note 20 and Honda CRV.

This happens periodically, 2-3 times a year.  I normally use Waze and it starts up when the phone connects to the car.  This works well for months and then all of a sudden Google Maps opens instead.

I have to pull over, and fiddle with options, and sometimes I can get Waze to start working.  At other times it takes multiple attempts at fiddling.  Sometimes, Waze isn't even on the list of apps (as displayed on Android Auto in the car), but it is present on AAs list on the phone.  Sometimes it migrates from the first app to the last app in the list.

Any idea why this may happen?

Is there a reliable way to correct it?

Pixel 2: How can I require a long press of power button to power up the device?
I have two individual Pixel 2 phones. Both list the same hardware version, build number, and kernel version in the Android settings. Both are running on Android 11, with the same updates.

However, for some reason, when powered down, one of the phones boots up at a short press of the power button, while the other boots up only with a long press of the power button. I have scoured the settings for any way to change this, but haven't found anything.

This is a problem for me because the one that powers on with a short press is stored for long periods of time in a backpack that I carry with me, and sometimes when I pull it out to use it, the battery has been run down to zero, I'm guessing because the power button got briefly pressed while it was buried inside the bag.

What is going on here? Am I missing something? How can I get the short-press phone to only power up with a long-press of the power button?

Why won't Chrome open GitHub .yml template?
We are using the GitHub Android app on our Samsung Android 13 Galaxy A13 5G.

We are about to create a GitHub issue, but we are headed into a
template=browser.yml URL that the repository owner set up for this particular issue type.

Why isn't Chrome showing up at the bottom here among the choices? It's odd  to see Brave there but not Chrome. Yes I tried setting each as the browser app for my phone. It doesn't matter.

! Browser list at bottom of screen]1

Chrome shows up on my other phone but not this phone. I checked all the Chrome settings of course, and the permissions of the Chrome app too.

Note I don't own the GitHub repository. I'm just trying to file a simple issue using the template. The same thing happens with any repository on GitHub too.

Anyway here is the intent:

```<code>intent://github.com/bitwarden/clients/issues/new?template=cli.yml#Intent;scheme=https;launchFlags=0x3000000;package=uk.co.ashtonbrsc.android.intentintercept;end

FLAGS:

FLAG_ACTIVITY_PREVIOUS_IS_TOP

MATCHING ACTIVITIES:

You might say well just don't use the GitHub app. Just browse the GitHub website with Chrome in the first place.

The same thing happens: Chrome tries to launch the .yml and it tries to call another app, it  can't even call itself recursively.


问:
full adb restore not restoring [unencrypted] .ab file to bootloader unlocked Lineage device
This is a follow-up troubleshooting question to this one here in this very same forum.

After repeatedly confirming the connection through both of adb devices -l and fastboot devices -l tantamounting to at least ~5½ of overall sessions for the restore command of a 7.95GB-heavy backup file, whenever there's a successful prompt after proper command-execution of the following:
adb restore <filepath>

But I managed to notice the constant: The restoration always gets stuck on com.qualcomm.timeservice quite oddly till time-immemorial, since I understand that I might be at fault somehow, somewhere — but in spite of that, if the latest builds of so-called AOSP do not support alarm-ringing during device shutdown [not caused by battery-drainage], I can safely conclude that the alarm did work during switch-off state of my device at least once. Doesn't that translate to the package working fine, instead of having gone corrupt by the time I created the .ab file?
More details for those who un-stereotypically can digest in-depth  text, they may get better context over there with some back-citation to key comments in that preceding question over here.
But other than the exact package which gets stuck, I should also note that I did try adb push <PC's .ab filepath> <device's root-directory path> after 1-2 trials-&-errors to determine which one is exactly it. It went upto 100% in ADB Enabled recovery mode, and then.. Failed to be stored by the time I booted the device last-time I clean-reinstalled the latest-build[ as I originally send this] of LineageOS 19.
The rest of the context is summarised there, except that I haven't tried bmgr of adb shell 'cus using bu help wasn't much of a help, so it slipped my mind to try creating backup through that method — nevermind restoring.

Cannot add new Certificates to Android Device
Using a Pixel 6a, running Android 13.

I am trying to install certificates from a private CA I have established on the internal network. I was able to install the root certificate by doing the following:

Settings > Security & Privacy > More security settings > Encryption & credentials > Install a certificate

From there I am able to select the ca.crt file I had copied from the CA server. I can see this new certificate when I hit "Trusted credentials" under the "User" section.

When I try to repeat those exact same steps to add a server specific cert, it's never added as I can't see it under "Trusted credentials". There is no error NOR a confirmation that this certificate was applied successfully.

Edit: When I successfully install the CA cert, I get a small tooltip/popup saying it's been installed successfully. When trying to install the non-root certs, I get no confirmation, and am simply returned to the previous UI view.

Gboard: how to stick sticker collection at the top
I am interested in a set of stickers called Tonton.

I found this set of stickers in WhatsApp as an addon listed as Tonton stickers by Tonton House. However, this set of stickers seemed incomplete, so I searched in Gboard with the search by text functionality typing tonton in the search box. This also yielded the other results I remembered.

However, now I would like to add these stickers via a Tonton icon at the top of Gboard, as I plan to use these stickers frequently and I don't want to type tonton in the search box all the time.

Other sticker collections appear at the top in Gboard, just like in WhatsApp, but I want to add the Tonton collection I found via search in Gboard to the Gboard stickers section of the keyboard.

How do I do that?

(As you can see, stickers collections appear under "My Stickers" in Gboard, but there doesn't seem to be a way to add the other stickers there.

Thank you for your replies.

Thanks.

(Indeed, when I click on the circled plus sign, I see lots of collections, but I don't see the Tonton collection (I only see it in WhatsApp, but the WhatsApp collection where I could download it is incomplete).

Can someone explain to me why I couldn't manage to achieve the desired result?

Thanks.

NOTE: after sending the stickers I was interested in ai was able to favorite them in WhatsApp by clicking them in WhatsApp and clicking on add to favorites, which makes them available in WhatsApp under the star icon.

However, I would have liked the whole collection to be available under an icon on Gboard.

How to set up PingID 2FA with third party OTP app
I would like to be able to generate pingID 2FA keys from a generic OTP app such as freeOTP for Android, authy for windowsOS or an OTP app of a smartwatch.

The service allows me to enrol 2 devices and at the moment I have a device with the official "pindID"  client.

To enrol the 2nd device the admin page generates a QR and provides a key/string

Updated:
Originally I was using the default QR or the 13 numeric string to enter manually.

But I've discovered that it is possible to generate different ones through selecting "authenticator. Then, this QR is recognized by 3rd party apps and the string is 32digits alphanumeric.

Now the device appears as paired in the pingID/pingOne console.

However,the device generated code is not working on pingID auth prompts.

BTW, there are differences with pingId client:
PingID client requires to log with a 6 pin password and code/token is renewed after seconds

generic OTP apps, don't require app and the code/token is renewed after much more time

How to play remote mp4 file through HTTP on Android TV
This is something that I've been able to do easily on a PC or an Android smartphone, but there seems to be something in Android TV (at least in version 9) that prevents it. I have video files in a remote computer and they are available for download through a HTTP server.

On the PC or the Android smartphone I just enter the full URL (http://.../files/video.mp4) in a web browser or in VLC player, it buffers for a few seconds and then starts playing.

But on Android TV this can only be used with small files. For bigger ones, it seems to be trying to download them completely (I see that by looking at the upload data rate on the server network interface). In a local network I would Chromecast it to the TV but they are in different networks.

I tried:

both with the builtin web browser and with apps like VLC and MX Player, all of them try to download the whole file first

Different file formats, including MP4 with H264+AAC which I know that the builtin web browser can play

Different HTTP server programs

HTTP and HTTPS

serving the files with MIME types video/mp4 and application/octet-stream

Is there anything more that I can try or is this impossible to do on Android TV?

Since its screen is broke, I have to do everithing manually from the adb shell, and since i'm having so many troubles with all the roms, I decided to make a little script to make my life easier.

This is what I got so far:

```<code>@echo off
setlocal enabledelayedexpansion

REM Factory settings

echo Formatting to Factory Defaults
adb reboot recovery
adb wait-for-usb-recovery
adb shell twrp wipe cache
adb shell twrp wipe dalvik
adb shell twrp wipe data
adb shell umount /sdcard
adb shell umount /sdcard
adb shell umount /data
adb shell umount /data
adb shell mke2fs -t ext4 /dev/block/platform/15570000.ufs/by-name/USERDATA
adb shell reboot recovery
adb wait-for-usb-recovery

REM Rom Flashing Section

set argCount=0
for %%x in (%*) do (
    set /A argCount+=1
    set "argVec[!argCount!]=%%~x"
)

echo Wiping /system
adb shell twrp wipe /system

for /L %%i in (1,1,%argCount%) do (
    adb wait-for-usb-recovery
    echo Flashing "!argVec[%%i]!"
    adb shell twrp sideload
    adb wait-for-usb-sideload
    adb sideload "!argVec[%%i]!"
    echo "!argVec[%%i]!" flashed
    echo.
)

REM Debug enable

adb wait-for-usb-recovery
echo Enabling USB Debugging
adb shell mount system
adb shell "echo '' >> /system/system/build.prop"
adb shell "echo '# Enable ADB' >> /system/system/build.prop"
adb shell "echo 'persist.service.adb.enable=1' >> /system/system/build.prop"
adb shell "echo 'persist.service.debuggable=1' >> /system/system/build.prop"
adb shell "echo 'persist.sys.usb.config=mtp,adb' >> /system/system/build.prop"

adb push C:\Users\ffpp2\.android\adbkey.pub /data/misc/adb/adb_keys

REM Booting system

echo Rebooting into system...
adb shell reboot
echo waiting for phone to boot up
adb wait-for-usb-device
echo Launch scrcpy
"D:\Users\ffpp2\Documents\Celus\zeroflte\scrcpy-win64-v1.25\scrcpy.exe"
</code>```

Now, I want to be able to evaluate every adb shell ... return code, so if anything happens mid way I can stop execution and I can get to fix what didn't work.

I havent been able to find anything regarding if adb shell forwards error codes back to the windows command prompt. Take a look at this:

```<code>D:\Users\ffpp2\Documents\Celus\zeroflte>adb shell mount /system
mount: mounting /dev/block/sda15 on /system failed: Device or resource busy

D:\Users\ffpp2\Documents\Celus\zeroflte>echo %errorlevel%
0

D:\Users\ffpp2\Documents\Celus\zeroflte>adb shell
~ # mount /system
mount: mounting /dev/block/sda15 on /system failed: Device or resource busy
~ # echo $?
255
~ # exit

D:\Users\ffpp2\Documents\Celus\zeroflte>adb shell cat asd
cat: can't open 'asd': No such file or directory

D:\Users\ffpp2\Documents\Celus\zeroflte>echo %errorlevel%
0

D:\Users\ffpp2\Documents\Celus\zeroflte>adb shell
~ # cat asd
cat: can't open 'asd': No such file or directory
~ # echo $?
1
~ #
</code>```

As you can see, no error code was returned. And, in theory, it should be returned, since I didnt used the -x argument:

```<code>Android Debug Bridge version 1.0.41
Version 34.0.0-9570255
Installed as C:\Program Files (x86)\ADB and Fastboot++\adb.exe
...
shell:
 shell [-e ESCAPE] [-n] [-Tt] [-x] [COMMAND...]
     run remote shell command (interactive shell if no command given)
     -e: choose escape character, or "none"; default '~'
     -n: don't read from stdin
     -T: disable pty allocation
     -t: allocate a pty if on a tty (-tt: force pty allocation)
     -x: disable remote exit codes and stdout/stderr separation
 emu COMMAND              run emulator console command
...
</code>```

Has TWRP anything to do with this?

How do I stop music apps from opening in the background/a notification when turning on bluetooth/bluetooth tries to auto-connect
As an avid music listener I have several music apps on my phone. Everytime I turn on bluetooth (or when bluetooth tries to autoconnect to a device without any device to connect to) several of my music apps open a player notification.

This is really annoying, especially as it slows down my phone while the apps are opening in the background (unless it has something to do with bluetooth connecting). This also replaces the current player notification (if I have one) on my homescreen, which is annoying.

Is there a way to disable this?

My phone is an Sony XZ2 Compact running Android 10.
The music apps I experience this with are: Spotify, Bandcamp, Mixcloud and DR Lyd.

Update: The answer to How to stop music apps from playing when connected via Bluetooth to my car/headset/receiver? doesn't solve it.

I've tested the app Bluetooth Connect & play which doesn't solve it.

I've tested this answer with Tasker and it didn't solve it.

SuperNote A5X - Cannot download
I've got a SuperNote A5X and I've installed some extra apps to make my experience better. I'd like to be able to download files (such as via a browser or cloud-storage app). None of these work on it. Some examples are:

Most apps (Tor Browser, EInkBro, Midori Browser) just say "downloading" and do nothing

Some (Proton Drive) fail with an error "system could not find any application that could create a document"

I believe need to install some sort of download manager for these to work, but I can't seem to find any. I also tried to copy my phone's apk to the supernote, but it didn't work because of SDK incompatibility (Phone was ~30, SuperNote was 27).

p.s. Please don't skip reading and then tell me to reset the device to get the factory app back, like in all the other similar posts. There is no factory app.

Are there models of smartphones designed to run on AC adapter/extern power supply permanently?
Basically, I want to use a smartphone as a fixed position audio player (and rarely for browsing), so I'm thinking, I could use a second hand smartphone for this. However, I'd like to have it plugged in DC power supply 24/7 - but I know most smarpthones are designed to damage the battery if you charge it permanently, so there is more waste and you buy more and spend more money.

So I was wondering - are there smartphones/smartphone models, that are designed to run off an adapter 24/7? As in, maybe they have a setting that you can turn on while plugged on extern DC power, which from that point on disconnects the battery altogether?


问:
Can't connect to WiFi network without phone reboot / fly mode turn on and off / connection to another WiFi on Honor X8 (TFY-LX1)
I recently bought a new Honor X8 (TFY-LX1) smartphone, it is running on Android 11 and Magic UI 4.2.0.191. It can't connect to my home WiFi network: any try to connect to the router gives "connection time-out". What can be done to determine the source of a problem?

A little details:

it's WPA2-Personal network;

other phones and devices can easily connect to the router;

the connection can be established from my phone when WiFi search is turned on and the device is rebooted, turned to the fly mode and turned off it, or connected to another WiFi first;

if connection is established, turning the WiFi off and on again leads to the issue again, until I take any action written above;

change WiFi frequency from 2.4 GHz to 5 GHz or reverse doesn't fix the problem;

seems like there's no effect from the 4G connection is enabled or disabled;

the Magic UI update is recent.

I can't really understand whether it's a software issue or hardware, or not even the smartphone issue but the network itself, but I've seen the same problem with another user of this device.


问:
Obb folder empty even though I can see inside data folder
I looked through everything I could find but I couldn't find a specific answer to this, sorry. I'm using a Samsung phone running android 13 - it isn't rooted and I can't risk rooting it. Both by using a computer through USB and through the AOSP Files app, I can see files inside the android/data folder, but inside the android/obb folder is appearing to be empty.

This seems strange, firstly as: I read that obb folders are only created when an app needs them, so I'm not sure why it would create them and then leave it empty. And secondly, because I would think there are other files inside these apps that are not showing up within the data folders, as some of the apps are quite big and there aren't files corresponding to certain things that seem to happen too quickly to be downloaded as they're needed - as well as, with how spotty the internet I use is, I would expect to have seen more connection errors as the game tried to access them if they were being downloaded each time.

Do I just not have the right permission to look in the obb folder, even though I can see in the data folder? And if so, is there a way to look inside it without root? For reference, I use a Windows computer. Thanks for any help you can give.

Edit: The file manager linked in this Reddit post about accessing the /data and /obb folders in Android 13 can apparently allow the user to access folders through launching the file manager as if it was within the app the folders belong to. However, even through this, the /obb folder appears to be empty on my phone.

The /obb folder is also empty in the com.sec.android.app.samsungapps app - could anyone with root access who also has that app look inside the /obb folder and confirm whether it is indeed simply empty, or whether I still cannot access it?

If it is truly empty, is there anywhere else that the data from a large app (.eg saved games, animations, character images - all things which I would think would be within the app itself due to fast loading speeds and the lack of connection errors, but are not appearing within the /data folder) might be stored that I am unable to find?

Edit 2: I've been looking into various ADB and ADB shell commands following this list of commands on Github. Is the adb shell pm grant <package name> <permission> only for things like giving permission to apps to use the camera? Or is there a way (not necessarily with this command) to use ADB to change things like read/copy permission? I have seen posts up until fairly recently say that you can still access data and obb through a PC, but they often don't mention how.

Permission to make a system sound
Certain apps make sounds that can be controlled by the "system" or "notification" volume level sliders.

But doing so of course affects the sounds of  all other apps that use these two volumes.

Is there a separate Android permission yet to not permit certain apps from making such sounds?

And as  I'm actually talking about the "start talking now cue" bell for various keyboards' voice typing, it's rather hard to identify which component of which app is actually making that sound too.

Suspend android: Alternatives that get close?
So, I have this Galaxy S6 running LineageOS 17.1, and I plan to use this device in my car as a head unit. I've set up everithing so that android auto (using HUR) auto-launches and connects to my phone, audio routing and etc. The only thing that remains to be done is what happens after you get off the car and let the phone there.

At first, I thought of shutting off the phone (using automate) as soon as power to the phone goes off, and when usb power exists, turn it back on. But then I asked myself how would I turn the phone back on? That will probably force me to modify the "charghing screen" (something that I dont know how to do) so that it boots the phone up instead of just charge. And even then, since I doubt that by modifying the sysem so hard I could reach boot times of 15 seconds or less (if you know how please tell me), I decided to instead get the phone to consume as little as nothing, so when I get into my car again it's ready to go.

Now, I know that there are some apps that claim to get the phone in a deep sleep state or "doze", where everything goes to a lo-power mode and in theory it extends battery life by a lot. Personally, I've never had to deal with those apps, so I'm kinda lost.

First, I would like to know what are the "best in class" apps that do that. I have to say that the phone has magisk, so it could be a magisk module, or simply an app.

Screenrecording calls with voice
I'd like to ask a question regarding screenrecording calls on discord or phone with sound.

Premise

I know that probably some of the readers will write about how it might not be that allowed or permitted because of privacy concerns, but from the other end I could also say that the speakers should also be wary of what they sort out of their mouths in order to preserve their privacy, and all of the latter shouldn't prevent in any way the first end's party to record the conversation in order to store the conversations and safeguard themselves in case of any contention or litigation. In a nutshell, privacy shouldn't prevent one of the parties to record for precaution and proof concerns, especially when this privacy can be kept by controlling what comes out of the mouth.
After a whole plethora of contentions with lots of people that I had UNJUSTLY lost because I could NOT prove anything of what'd been said to me, I decided to take the safeguard route which I'm currently finding hurdles with.

After this little written digression, how can I screenrecord phone or discord calls with voice? I tried the in-built screenrecorder and the whole set of task-related apps but unfortunately the first does not work and the second type either screenrecords soundlessly or it does not screenrecord at all when it comes to calls. How can I manage to circumvent the whole block? Does it relate only android? I'd be glad to receive exhaustive answers and on point about SCREENRECORDING calls with VOICE, not simple records, not recording with a second or third device.
Thanks to every answerer.

Shut down Android TV
I have a Philips 58PUS8505/62 4K LED Android TV. Normally, I want to power off the TV by switching off the power outlet the TV is connected. However, the TV or its remote does not provide a menu or key combination (that I know of) to shut down the operating system and power off the TV before I cut the power.

When I press the red (power) button on the remote, the TV goes into standby. However Android continues to run and I see disk IO on the external disk connected to the USB port of the TV. I know how to "unmount" the external disk, but my question is not on this.

I tried to long press the power button on the remote (external TV boxes work this way), but nothing different happens.

There seems to be no way to power off the TV. What am I missing?

What makes Android running on a TV resilient to abrupt power off events?
What makes the Android running on a TV aka Smart TV resilient towards abrupt power off/outage events?

By abrupt power off I mean manually turning off the electrical switch to which the power cord of the TV is connected to, or removing the power cord from the electrical outlet, while the TV is still functioning.

If I do the same thing to my PC running a Linux distribution, on next boot my OS would always find that the system partition is in inconsistent state and the OS would try to repair it before moving on with the boot process. That being said I always expect that some of my programs and the data associated with them might no longer be in consistent state. Perhaps the changes I made to my document were no longer saved, or the N number of file that I instructed my file manager to copy seems to not have been copied correctly, and so on.

On an Android TV how come this problem of file corruption and inconsistency not affect the Android apps per se? They all seem to work fine no matter how many times I abruptly turn off the TV. In fact, my Sony Smart TV running ancient Android 4.4 does not offer Shutdown/Power Off option at all. There is only standby mode. One manufacturer, Philips, also recommends turning off one of their TV model completely by pulling out the plug from the electrical outlet. To me TV manufacturers are very confident that their Android TV would continue to work correctly after all these abrupt power outages.

How come? And if Android on a TV is so much resilient than why do Android phones offer such fancy Power off feature where the user has to wait for N seconds before the phone completely shuts off? Why not just kill the power from the processor? That would be convenient to the user. I press Power off, and lo and behold, the phone shuts down right there.

I tried to search about Power related docs on developer.android.com and source.android.com but could not find the answer.

Google Maps switches to "keep north up" automatically when car stops at traffic lights
I know about the setting "Keep map north up" and I always keep it disabled.

While I'm driving, the map correctly displays the road ahead as "up" - for me it's the simplest way to interpret Google Maps' directions.

However, when I stop the car for whatever reason (traffic, pedestrian crossing, red light and so on) the map spins so that north points up.

When the car starts moving again, the map spins yet again and reverts to "road ahead as up" - all this happens without me even touching the phone (I'm not tinkering with settings while I'm driving!).

This behaviour is very confusing and I'd like it to stop. I don't know when I first started noticing this, but it's not a recent change. Google searches seem to indicate that no one else has this problem.

I'm using Google Maps 11.66.0602 on Android 11 running on a Samsung Galaxy A20e.

recover data from Huawei G610-U20 boot loop
My phone is stuck in boot loop, I think because not enough memory (RAM) is available to start the updated version of Android. In fact, after upgrading Android in 2021 the boot loop appeared, and then after 30 mins of loop the phone would finally start. This happened a few times, before I upgraded again and it's been stuck in boot loop ever since. On my computer, I have noticed that androidx86 is stuck in boot when not enough RAM is available, therefore I deduce this might be the cause. Internal storage should not be full on my phone...

I could try and downgrade the Android version, because I can't think of any other ways to access the internal storage (either by disassembly or by alternative boot options).

I can start recovery mode POWER + VOL+, however if I press VOL- + POWER, then only one line of microscopic writing appears on the bottom of the screen, and it's impossible to decipher what is written.

Wiping cache does not help. Firmware download mode accessible. As far as I remember: Not rooted, USB debugging enabled.

It would also be useful to be able to search in WhatsApp for contacts using the "Nickname", "Phonetic first", "Phonetic middle", and "Phonetic last" fields. Right now, WhatsApp only seems to search the "Prefix", "First name", "Middle name", "Surname", and "Suffix" fields.

Reset Digital Wellbeing timers
Everyday I set digital wellbeing timers to zero(0) and increase then by 5 minutes everytime I need access to an app, this is how I'm coping with my phone addiction.

Sometimes if I extend an app timer to 30mins someday it remains the same and I will use the app for 30mins everyday until I realise and put it to 0-5mins again.

So, is there a way to reset these timers everyday to zero ?

Apps mobile connection while of wifi

Some third-party apps, such as online banking apps, may still consume mobile data even if they are connected to a Wi-Fi network. This issue occurs on all Android phones and cannot be resolved by changing the settings on your phone

Can someone explain this to me ? What permissions are needed to force mobile data while on WiFi ?

Is it possible for a Bluetooth device/button to wake up an Android phone and take a picture (hands free)?
Long story short, I am taking daily progress pictures and I am trying to take a picture with the phone without touching it or using a timer etc. Totally hands free.

The phone is a spare Samsung note 10+ mounted to the bathroom mirror and permanently connected with the back camera facing forward. Touching the phone isn't suitable because it's facing the wall and movement has the chance of bumping the position slightly (not ideal).

After experimenting with Bixby many thanks to the comment by @Morrison Chang, I found it does work hands-free suitably for my partner and myself, however listening to my partner trying to tell the wall to take a photo in a slow robotic voice is not optimal. So, the question remains,

Can a Bluetooth attached button wake a phone and trigger a picture to be taken?

Note: I am a career programmer so writing a simple app isn't out of the equation if need be.

Xiaomi Portrait Mode: Where is the original data stored (before depth-of-field effect)?
My Xiaomi 10T Pro has a "Portrait Mode" which blurs the background. When opening such a photo in the Gallery, the phone offers the option to adjust depth-of-field.

By default, a medium amount of depth-of-field is used. If I transfer that JPG to my computer, the background is slightly blurred.

When I open the picture in the phones Gallery app, it allows me to adjust depth-of-field and make the background more crisp. That must mean the phone stores the original image data somewhere. Otherwise, it wouldn't be able to un-blur the JPG file.

Where is that original image data stored?

How to determine the architecture (32 v. 64 bit) using only the phone
On a computer, it's pretty easy to find out if the system is 32 or 64 bit.

I have a Nokia G21 and a Huawei P10 in front of me, and both tell me the various things: the model designation of the phone, the CPU, the Android version; but nothing tells me explicitly the architecture, i.e., whether it's a 32 or 64 bit device.

Microsoft Windows, on the other hand, tells me in no uncertain terms at Settings -> System -> Info which one it is. Linux is also pretty forthcoming with this information.

Is there any means from the on-board tools of Android to find this out?
I.e., not asking the internet, not connecting to a PC and not installing any additional apps.

How does Tasker share data with plugins?
After years of struggling with near "blindness" from using Tasker 1.3.3u2 on an old e-ink device (Android 2.1), I decided to take a serious look at modifying the theme. I finally managed to chase down all the textColors and change them to black while changing almost all backgrounds to white. This required changes in not only layout xmls but also a few smali files.

Needless to say, the signature is broken, but a resigned copy still functions well--except for plugins.

I knew this was coming because a few years ago a software update for the e-ink device made it refuse to install the original Tasker app--unless I resigned it. I still don't know why.

To the point: how does Tasker pass information to plugins? I thought there might be a shared uid but nothing in packages.xml suggests any connection between Tasker and any of the plugins I use (Minimalistic Text, Rotation Locker, Screenshot Easy, Desktop Visualizer).

Task steps involving plugins are ignored if Tasker is resigned. Compiled kid apps (using App Factory) work as intended, including plugins. This is good because I never use Tasker itself unless I am working on a new project or debugging an old one. I always make stand-alone apps.

But...I can keep one device with the original version of Tasker (and old software) for development, except the whole idea was to make it easier on my aging eyes when I'm doing serious creative work, so that's a loss.

Does anyone have an insight into how plugins communicate with Tasker and if there is a way I could restore those lines of communication in a resigned Tasker? (I've already tried resigning the plugin apps with the same signature. No dice.)

Samsung Galaxy A10 asks for password after update to Android 11
After updating my Samsung Galaxy A10 to Android 11, I get the message "your password contains at least 4 characters, including at least one letter" so I can't unlock my phone's screen. I didn't set any password before, I had a swipe lock. I want to copy all data to the computer and then do a hard reset (I have password to google account so FRP won't be a problem).

I tried to unlock my phone and backup to Samsung Cloud via Samsung Find My Mobile but remote unlock is disabled.

When I connect my phone to my computer, file explorer doesn't detect my phone (I can't enable MTP mode).

USB debugging is disabled

Entering default_password also didn't help (maybe it's new default password for Galaxy A10?)

Is there any way to copy all data to computer or unlock my phone without losing data?
