Short story about "why does my Pixel 8a keep dimming itself even with adaptive brightness off":
Googles display config for the 8a is overly conservative. Two things make it bad:
The sneaky one is (2). You watch a video, phone warms up a bit, screen gets dimmer. You push the slider back up. It creeps back down. Welcome to Googles factory settings.
Fix: patched /vendor/etc/displayconfig/display_port_0.xml via a Magisk overlay ā no system partition writes, fully reversible. Default 140 ā 200 nits. Thermal caps (light/moderate/severe/critical) all raised. HBM untouched.
Works on mine. 9a next to it, 8a visibly brighter. No panel damage, no battery drama ā all values stay within the panels designed operating range. This was pure software conservatism.
