Hi I have recently bought a second hand redmi note 8 pro to use with a drone I have also recently purchased.
everything has been working fine. Until last night 21/07/21 I had a notification of the new miui 12.5 update. which I left to do its thing. The issue is the screen does not respond to touch. it appears to boot up ok gets to the screen shown. I have had it on fastboot screen and also wiped all data (can't seem to get mi assistance to work.)
Has anyone else had the update/ issue?
How would you recommend proceeding.

I have the same problem (Redmi Note 8 Pro Global - MI firmware). After updating from 12.0.8, the touchscreen stopped working.
I had to roll back through the fastboot. I also tried to flash version 12.5.1.0 via fastboot - the problem persists.

The phone had a replacement display module, but with an original one.

There is an idea to try to flash it with a version for Indonesia or China, but so far I have not tested it.

I have exact same issue on this update. I also replaced the screen some time ago. I belive it's android 11 problem, because CFWs like PE doesn't work too. ROMs with Android 10 also seems weird to me, because digitizer keeps "jumping" and clicking random places. Android 9 - all works perfectly fine. I am going to find out which partition is used to use touchscreen and check if it's possible to flash it over PE ROM to solve the problems.

I have some problems after updating to MIUI 12.5.1:

1. Have to repeat the procedure twice for uploading any picture from gallery to anywhere on Internet. It doesn't work in first attempt.


2. Fingerprint sensor shows many errors off & on. 3-4 attempts to open the phone. Tried re-registering my fingers.

3.
Option of Completely Hide Notch gone

4. While playing Facebook videos, sound continues, video stops.

Too annoying these bugs are.

5. Battery drain ("...even on miui 12.5 battery drain too much high...")

Yes, the great manufacturer has kept its information behind the mountain. I have just found a contribution to this in the mi community.

It only briefly mentions that repairs should be made with an official display. I also do not understand why Xiaomi makes such a secret of it and does not give the reasons. Link

I have installed the Global 12.0.5 Stable QGGEUXM and I am also aware of these display anomalies.

Do you have any results in the project?

I've tested all partitions but any of them seems to be changing display driver. So sorry, no luck there, I think we're stuck with android 9. It looks like it is hard-coded into firmware.

    Issue with SIM selection for calling on MIUI 12.5 Global - Redmi Note 8 Pro​

    renderTimingPixel.png

    Anyone experiencing this bug with default SIM for call?
    The Google Dialer will ask for which SIM to call on reboot even tho I already set it as SIM1 or SIM2 in the Settings.
    The workaround is manually reselecting the SIM but only effective till next reboot.
