Hello, my A30 screen was broken because of falling. Now I already change the screen with the cheap one because I can't afford the original super AMOLED. The replacement screen was an LCD. But when I use the phone for gaming the screen sometimes goes black but the backlight is still on. After hours of diagnosing I found out that when I put my finger anywhere on the screen, then I put another finger on the top area of the screen ( around notification bar ) the screen goes black. I never actually use samsung A series before, my last phone was J2 Prime. I just want to ask is it a feature that only works on AMOLED display or is it a firmware bug or something else? Thank you.
Hi, thank you and sorry for the late reply. Just got the email today. My screen somehow get fixed by turning on and off the Game Launcher feature. Not sure if it was the main cause of the problem but it's working perfectly now. I also updated my phone to the latest patch just in case it was a system bug.
