Question Auto brightness problem

Search This thread
Hi all, I used this 11 ultra for about 3-4 months, everything work well, but suddenly in few days ago, my screen auto brightness is darker thân before. I think auto brightness sensor is dirty or some dust maybe block it from function. But i dont know where is that sensor to clean it😂
Can someone show me the way to fix it, thanks alot 🥰

i dont think it's my problem, before few days ago, everythings work perfect, only now it is too dark
Can't help you then. One of the reasons why I like this phone is that you can enjoy the superior hardware while fixing any software issues (which you can be sure to expect) because it's so easy to root
Yeah, i know but i dont think i need root. When i first use Android, im very excited to root and do blah blah things. But its the story of 10 years ago. Now I can live happily without root :D

I used this brightness fix again today, each time you flash another EU Rom you might need to flash it again but it is effective
