All sensors (acceleration, proximity, brightness, etc.) not working after July update

[bluesheep13]

Hello dear xda community, this is my first post here, so please be gentle

I own a Xiaomi Mi A2 Lite 4/64GB version (Model Nr. M1805D1SG), and lately all of my sensors stopped working. I am quite sure, though not 100%, that this is related to the recent July update, as I did not perform any other major system changes or even app installation in the time period since I've noticed the sensor malfunction.

I first noticed the proximity sensor not working any longer as the screen kept staying on while I was taking calls, which caused me to mute myself a couple of times during phone calls, by accidentally pressing the mute option with my check. Then it became apparent that auto rotation also was not working any more, and after a while I also noticed that my brightness was not adjusting itself any longer. I confirmed the faulty sensors by going into the hardware testing menu (by dialing *#*#6484#*#*).

Now since all sensors malfunctioned at once I highly suspect that this is an issue related to software and not a true malfunction of the physical sensors. Has anyone else experienced similar problems since the July updates, this an issue known to appear at times after an update? I'd be very thankful for any directions and/or help in this regard. Thanks for any input on this issue, cheers!

EDIT: The problem still persists after a factory reset.

Android version: 9
Build number: PKQ1.180917.001.V10.0.12.0.PDLMIXM

Restore factory settings.
If you do not resolve, assistance

Thanks, this would have been my first approach, but I first wanted to see whether this was a common issue, hoping for a possibility to prevent the time-consuming task of reconfiguring my phone after the factory reset. Probably I'll just have to bite that bullet and set aside a couple of hours to customise my phone again afterwards.

Just performed a factory reset, my problem unfortunately still persists.

How about the touch sensitivity? Is it affected too?

I did not notice any deterioration in the touch sensitivity during my everyday usage, so I would like to say no. However I do not know how to quantify the quality of it, or how it test it, so if you can provide steps for testing the touch sensitivity I might be able to give a better answer. Either way, thanks for replying!

Ahh.. then there is no difference in your touch sensitivity. If I handover my phone to you, you will definitely feel it within a minute. My situation is that worse! Please check the "July update" thread in this same forum if you want to know more.

Interesting, i had similar issue previous month. I thought it is hardware issue - but after july update sensors are working. Maybe wait for august update.

Did you try reflashing your phone bone-stock with the latest firmware?
Maybe some data got messed up in the OTA update process and of course resetting won't help you, because the data was being modified permanently in the system image.
When you reset your phone, it places the "bug" again in the system because the system was altered with a corrupted/buggy/damaged file/files.

After the July update I have a big problem with the fingerprint sensor!

I was about to go down this route, however yesterday the August security update came OTA and it seems like everything is working again! Thanks for the tips everyone. I will probably wait with the next update and see if any new problems pop up on this forum, lesson learned!
