[Sami Devo]

Hello... Am using Android 10.. having proximity sensor issues.. can i switch to Android 9?
If so then how?
Bootloader unlocked..
I need to fix the sensor bug during call..

Yes you can, though you will lose all sensors :/ and then you will have to install a custom rom for getting again the sensors...

I've successfully rolled back 3 times using this method. I have to note that the custom rom must use a pie vendor for the sensors to work on rollback. Last time i downgraded, it was april i think, pixel experience was still using a pie vendor.

In my case Widevine L1 was preserved. However i strongly suggest checking detailed guides before attempting to downgrade.
