So I have this problem with my A52, it's only one years old and it happens pretty random as well. The middle of the screen doesn't respond to touches in a vertical line, on the edges it responds well. Basically because of this I can't unlock the phone not with the fingerprint either with my pin code I am using. Also can't turn it off because if I hold down the side key the turn off and restart buttons appear but they are also in the middle of the phone, the zone where it doesn't respond for anything so I can't turn off or restart it. In a few minutes it works normally if nothing has happened, but it is quite annoying.
Do anyone have an idea what causing the problem, or have the same/similar problem to this one. Thank you!
