[Redmi Note 7] Auto Brightness Failure

[adityasathis]

There was previously an issue with brightness flickering that was resolved using the command below:

setprop persist.sys.qcom-brightness 4095

However, adaptive brightness does not work and enabling/disabling every odd time prevents the proximity sensor from running during calls (might be due to wakelocks not being released).

From logcat, this is the line I get when I try to enable adaptive brightness:

04-27 22:21:51.229  3471  3637 E LightsService: Light requested not available on this device. 2

Hum, many people reported various issues about Redmi Note 7, but noone reported manual brightness issue, that's weird.

You're using stock, official vendor from Redmi?

For auto-brightness, can you check in any sensor-reading app that the light sensor seems to work? (value decreases if you put your phone in a dark area)

Same problem with adaptive brightness here.
I've checked the sensor functionality using an app and it appears to be working.
