Hi,
the fingerprint sensor of my X720 suddenly stopped working a couple of weeks ago. At that time, stock ROM was installed on the device. I thought that it could be a software problem, so I tried several custom ROMs, but the sensor has been keeping on not working. Checking dmesg on a terminal emulator, some strange error messages appear, as you can see in the attached image.
Has any of you had the same problem?
Nexus 6p, unlocked bootloader and running 8.1DP.
Whenever I make a call and put the phone to my ear the screen turns off and never comes back on. I tested the sensor with the device info app and I the sensor stays in the "close" position when engaged untill the app is restarted.
I did some research and I found that some users had this issue with the Nougat update but no relevant solutions were found and the 7.1.1 update fixed the problem.
I would like to avoid factory reset or locking the bootloader if possible.
Can anyone think of a possible solution?
I tried the Proximity sensor reset app from the play store and that does absolutely nothing.
EDIT: Stable 8.1 doesn't fix the issue, even after clean install and manual flash and wipe.
I'm on SuperXe 8.0 Oreo built and it works flawlessly. I remember having that issue on nougat ROMs use to drive me nuts. Every time I needed the keypad I had to fight to get the screen back on. ?
Not a factory reset. Manually wipe the phone and apply the latest 8.0 image.
So after manually flashing the 8.0 image everything worked. I thought id give 8.1 DP2 a shot and I wiped and flashed this manually. It worked during the restore but stopped working after all my apps were back, so I thought it may be an app that's causing the problem. Strated in safe mode, issue is still there. I guess Ill just have to wait for the stable 8.1 release. If anyone else is facing the issue please post here.
Hello,
I've been without sensors nor camera for a while now (almost a year), got broken because an OTA update. Tried downgrading, didn't work.
Yesterday I managed to root and install TWRP, did some research and heard about ''persist'' partition. I've been searching for similar cases but no luck. Also tried deleting sns.reg
Can someone provide me the persist.img stock file? So I can finally fix my sensors.
Broken sensors:
Gyroscope
Ambient light
Accelerometer
Proximity
Fingerprint
Camera Flash isn't working either.

Solved, download the firmware version you have here and look for persist.img. The firmware comes with it but the install script doesn't use it. Just flash it:
Code:
fastboot devices
fastboot erase persist
fastboot flash persist persist.img
fastboot reboot
Hello friend,i have similar problems,apart from fingerprint sensor,all my sensors and cameras,camera light are not working,will i loose imei numbers if i flash the persist img ? i dont know how to flash persist img,can you help me please?
Edit: hi i actually fixed my problem by flashing persist.img, all sensors and cameras are working now
Thank you so much
I would like to thank you for this solution, finally, after 2 days trying I have my ZS570KL alive and working faster, I had to try rooting, then it was bricked for some hours, finally I got it rooted, but after deleting that persist/sensors/and.reg it was the same... until i found this thread, everything works good!!! thank you very much

Did you also have broken sensors issue and it is fixed now? I want to try it on my ZS570KL too, but is there a persist.img for this phone?

Depending on your OS version yes, contact me on Telegram @GuerrillaRadi0 (the last character is zero) maybe I can help you, after I fixed the problem I configured fingerprint security and the problem came back, so I tried to flash persist.img again and it didn't work, so I got the raw rom of the Oreo version I have; WW-15.0210.1810.73, which comes with its own ADB, and flashed from there, the same raw rom has the persist.img. After that all sensors worked again, so I configured fingerprint security again just to be sure, and again I lost all the sensors, but after deactivate fingerprint again everything worked fine, I guess I have some hardware issue related to fingerprint sensor, I guess it was because a technician opened the phone to replace screen and battery 2 months ago. I always used fingerprint so I need to go back to pattern.
Good luck
After some days without any issue the problem came back, I flashed persist.img twice and it worked, but about 3 days ago I can't solve this flashing persist.img, I tried wiping everything, downgrading to Nougat, then flashing Oreo, with TWRP and via flashtool, no solution, any other idea?? all sensors are not working.
Thanks in advance

The touch works fine but sometimes it completely stops working. Physical buttons continue to work. After restart it usually works fine.
What are the latest solutions to this in order of least work to most work?
I have already tried wipe cache clean thing. Right now I am discharging it completely to check if that works.
Try safe mode to rule out a 3rd party app.
Any updates or recently added or uninstalled apps? Prime suspects...
Viewing what apps are running/cache before/after the glitch may help you spot possible suspects

hi did you find any fix? or reason why it happens. My device Redmi 8A shows this issue. Touch starts responding, screen off and on solves temporarily. Never faced this in MIUI ROM and mods, These issues are only in custom rom.
So I flashed lineageOs 17.1 unofficial build on my phone earlier to test it out. After booting into it, I realized the fingerprint sensor wasn't working so I flashed the stock rom using odin. After boot, fingerprint sensor still didn't respond and when I try to add a print, I get an error,"make sure the home key is clean and dry, then try again.", so I used the dailer code (*#0*#) to run sensor diagnostics. The results are as seen attached. Is there anything I can do about it? The home button still works fine so I doubt its a hardware problem. If anyone has a fix for this i'd be grateful for you to share.
