Settings App crashes every time I Try to change screen lock option.

Hi
Recently I've unlocked my Z5's bootloader and rooted it.
I installed Paranoid android from the thread in the forum, everything was working fine, even the fingerprint sensor was working quite ok.
after a day I wanted to switch the locking option. so i wouldn't use the fingerprint, and only swipe to unlock the phone.
After i changed the settings the app crashed (it changed successfully to swipe instead of using fingerprint)
Now the result is that every time I try to change this specific setting (Screen Lock) the app asks me for my pin, I type it and the settings app crash.
I tried to restart, Clean cheche and uninstalling some google apps. nothing helps
Thank you for the help! :angel:

So obviously it happened because I am no longer stock, But as my experience goes, I know people may have stumbled upon the same problem in their past, and maybe know a solution that will work for me.
I do not want to go back to stock, Because Sony's Stock is ****, serious **** full for bloatware that you cannot remove and battery life that makes you cry.
Your message was not helpful, but thanks for trying

It most likely is a problem with the ROM installed on your device, as you already performed wipes and the problem persists. Try reporting the problem to the rom dev or if its that important, try a different rom for now
Good luck

Fingerprint sensor issue

Hi,
After updating to 7.0 nougat by official Europe update,
My fingerprint sensor stopped responding, when I'm trying to add new fingerprint it wouldn't let me even try, It shows a message (Attention: make sure that the home key is clean and dry, then try again) and then it goes back to the main lock screen settings menu.
I'm really desperate, already tried everything, plz help!
:crying:

Have you tried to factory reset or just flash android 7.0 with Odin. I would recommend wiping after installing an update like 7.0 anyway updating always causes bugs and issues for me.

I also just updated my SM-G935FD via OTA to Android version 7.0.
Since then, fingerprint scanner is not working. Like for OP, all tests fail under HwModuleTest.
I tried to remove all fingerprints, but it is impossible to add new fingerprints - the error message is "Make sure that the Home key is clean and dry, then try again." Obviously, the fingerprint sensor is as dry and clean as it was before the update (when it worked perfectly).
Since then I tried, unsuccessfully:
- removing old fingerprints and adding new fingerprints (does not work, cf. above)
- formatting cache partition
- performing a hardware reset
- flashed the stock firmware G935FXXU1DQB3 with Odin
Please advice, thanks.

If you have tried to flash stock firmware in Odin, I'm really not sure what the issue is, if it was just a glitch in the software it should probably have been fixed by a wipe and flash with Odin. If your phone is still under warranty I would bring it back into the Samsung shop or contact them over the internet to inquire about fixing it.

The same exact problem has happened to me too . I'm tired of unlocking with patterns
What should we do ?
This cannot be a hardware issue cuz phone was fine right before the update

Do you still have the issue ?

I have the same problem ???
What the way to fix this issue

I had that problem sometimes and in the end the main reason was really sweat on my fingers and dirt on the home button.
I know this doesn't sound like a solution, but it surprised me as well. Just try drying your fingers and clean the surface of the home button.

Hi There! I encountered the same issue earlier but then suddenly my fingerprint sensor works normally. The last thing I that I made changes to my phone was to reset the password of my samsung account. Not if there was a security breach that happened but after resetting the password, works fine for me. I suggest that you back up your phone's data before and after resetting your Samsung account.

I have this problem for 1 year, tried to change the password but didnt work.

IS someone still struggling with this problem ? Yesterday i upgraded to DevBase 6.0 Oreo newest build. But after the flashing process the fingerprint sensor act in a unusual manner. Sometimes i could unlock the phone sometimes it directly jumps to the pattern unlock screen. Any news about the problem ? I wiped cache/dalvik and i resetted my password of the samsung account - nothing helps.
Any help, ideas, links are highly appreciated
Cheers

Fingerprint sensor stopped working

Hi,
A few days ago, I was on official Pixel experience rom. Fingerprint unlock started to don't work sometimes. I had to wake up screen with power button before using fingerprint sensor to unlock the phone.
Yesterday, my phone just stopped to react to any fingerprint unlock attempt. I thought that was a software issue, so I decided to migrate to LineageOS. That was a success. However fingerprint sensor doesn't work. Worse : fingerprint settings just disappeared in phone settings.
I would like to know if there is a way to test the hardware part. Or if anyone has gone through this before, any advice will be appreciated.
Thanks.

I had the same, but I do not remember exactly how I solved it. I think by clean flashing a MIUI developer rom, booting into system, flashing twrp again, format data, and flashing my custom rom.

Thank you for your answer. Do you think I can do a full nandroid backup of my current setting, then format to install MIUI, then restore my backup so I don't lose my data?

You should. I had difficulties with restoring a Nandroid backup, but that was probably related to encryption. So by removing your PIN or password it should work. I used the app Migrate to restore my data.

Thanks. I gonna try that when I get some free time

OK, that was a hardware issue. Everything works fine now. The fingerprint sensor flat cable was mounted fold. This must be the reason.
If someone has the same problem, it's easy to fix it by yourself. You can find cheap tools and part on aliexpress, and disassembly videos on youtube. This took me 30min and it was the first time I opened a phone.

OnePlus 6 Android 10 Beta 1:all sensor dead after root

Hi guys,
I have installed Android 10 Beta 1 on my op6, all the sensors stop working after the phone rooted.
I tried uninstall magisk,and all the sensors go back normal after a reboot.
Both magisk V19.4 and V20.0 had been tried.
Any idea?
Thank you very much.

You should reboot twice or a factory reset if the First solution doesnt work.

Q has sensors off feature, it might have been turned on by some mistake,
Go to developer options, quick settings developer tiles, tick "Sensors off" option, you'll see new unremovable tile, change it's status several times & see.
Good luck

Thank you all guys.
I reseted everything in twrp.
Root and sensors are all working now.
Thank you.

For me, also all sensors are not working after updating to Android 10 open beta 1, even without root.
I already tried flashing it again and cleared cache, but it didn't help.
Is there anything else I can try to get sensors working again without resetting everything?

For me, I have to reboot few times ( lost count of how many times I have rebooted ) until the sensor is working again.
It's not permanent fix though, another reboot could make the sensors stop working.

I've another problem that a smiley in the Notification only appears as "?". Is happens also in Chrome with some symbols

I fixed it by uninstalling Magisk via TWRP (there's now an easy guide to install it in Android 10), rebooting to system, check if the sensors are working again, and then reinstalling Magisk through TWRP again. If this happens again just re-do the procedure, an update will probably fix this.

How weird ô.O
Magisk v20, rebooted multiple times, nothing worked :|
I just reboot one more time while reading this post ... it works ...

The fonts problem.
The size of some fonts became 0 byte.
Try to reinstall the fonts or reinstall the rom .

It seems that the V20 is not compatible with android 10.
I installed v19.4 instead.

Yes,after uninstall magisk all sensors are working again.
I need both root and sensor. So I try to reset the phone .

For all you people with the sensors issue. Install magisk 20.1 that'll fix this issue

Screen lock was already changed, try again with the new screen lock

Hi,
After unlocking the bootloader with the latest official app, I cannot change the screen lock method of my Zenfone 6 with a message saying "Screen lock was already changed, try again with the new screen lock" and I can only choose "None" or "Swipe". The fingerprint breaks as a consequence because it relies on PIN/password/Gesture.
The phone comes with a fingerprint + password authentication before the unlocking, which seems to cause my issue due to mess-up of the TEE. Factory reset / Reflashing the whole image doesn't work.
Anyone experiencing similar issues? Is there any way to re-enable other unlocking methods?
Thanks!

Same happened to me,
I got back the pin option only when I relock the bootloader.
I used the official asus application, I'm gonna try the adb unlock option

Same thing here. Unlocking the bootloader breaks it. I fixed mine by flashing the downgrade to P zip, setting my phone all back up and then updating to Q. You might be able to just reflash Q and have it work, but if that fails go to P and then upgrade. Haven't had an issue since.

Did you downgrade to P being bootloader unlocked? If so , did you use the official asus method with their apk, or did you unlock with adb?
Thanks for your response !!!

I can confirm that reflashing stock Q image doesn't work.

I could never get the adb unlock method to work at all. I used the app to unlock, stayed unlocked and flashed back to Pie, then updated to Q

So, I am on a custom ROM, but I understand that you solved this on stock. Does anyone have experience how this can be solved on a custom ROM? Thanks!

Hey, I was having the same problem and tried doing several things without success (Like deleting files in the /data/misc/keystore, changing different ROMS, etc). What fixed it for me was restoring the vendor partition, the problem was that I removed the enforced encryption flag and that was causing problems with the GSIs I was installing.

how did you restore the vendor partition? did you use the backup on twrp or something? is there a flashable zip?
also did this happen after you unlocked or after you installed a custom ROM with encryption disabled?

Did you guys manage to fix it? I actually have the same problem with my Redmi 8A after flashing Magisk on Havoc and Stock ROM. I tried to delete the locksettings. db and .key files but i still can't set a pattern or PIN

Spot on !
Removing the .key and lockfiles from /data/system works !
I can set PIN again

....

Swipe TWRP on your phone, enter the system, and delete 2 locksettings....file in the DATA\ SYSTEM\ folder directory.. The file at the beginning can be successfully protected by restarting and setting a password or fingerprint.
