Maximum brightness on FP4 is not bright enough

Dont agree the general max brightness changed however since Feb with Sun/Heat the screen dimms while the slider stays at max as discussed here which is indeed related to the topic you linked

Random Screen dimming (while brightness slider stays at 100%) after A12 update

After updating to Android 12, the rightness of the display of my #fp4 randomly decreases, but eventually temporarily reverts to correct brightness, repetitively. The period of time during which its brightness is less than it should be is always greater than the period of time during which its brightness is correct. This has solely started to occur after the Android 12 update, and occurred approximately immediately subsequently, so I have cause to believe that it was caused solely by it.
