Yeah I will overall it doesn't have unless is almost reaching the max brightness and sometimes I have to restart the phone cuz it goes dark af when I unlock it lol.
I was scared cuz I brought this phone from swappa and I thought it was dying or something but it never did that till after the update so I guess I am fine lol.
I have this same exact issue after updating too. It either flickers with horizontal bars, or has a washed light greenish tint overall. It is definitely from the update and extremely annoying that I cannot get help for it.
