Tablet Z dims to 48% after c.5 seconds

All configurations tried, including Mobile Bravia engine toggle and adaptive display toggle but tablet keeps returning to +48 on -100 to +100 scale.

Also tried using lux to fix but same problem.

Would appreciate help as this has effectively bricked the tablet in all but a blackout room.

Cheers

have you tried booting to safe mode?https://talk.sonymobile.com/t5/FAQ/How-to-boot-your-phone-into-safe-mode/td-p/348008

 

disable adaptive brightness

adjust sleep time

disabling smart backlight control

 

 

does your light sensor work? try to run diagnostics. https://talk.sonymobile.com/t5/FAQ/How-to-boot-your-phone-into-safe-mode/td-p/348008

Do you have any brightness control apps that could be conflicting with your system settings, power saving apps too.
