How to solve brightness problem after screen replacement?
I bought an unoriginal screen to replace my broken screen on my Xiaomi MI A1.
I did the replacement but as it's not an original screen, there is a problem with brightness :
When I boot the phone, the Xiaomi logo appear with a normal brightness. But then, when the logo disappear and the home screen appear, the brightness become extremely low (can only be seen in a dark room).
Everything else works perfectly (touch, apps, ...).
Even if I move the brightness bar, the brightness doesn't change. I also tried to change it with apps but it didn't work either.
The weird thing to me is that the screen is able to have a good brightness (because when the phone boot the brightness is good) but when in use, the brightness is terrible.
So, is there a method to have a good brightness on an unoriginal screen after a replacement ?
Thank you !
