My screen sometimes got glitches quite frequently. Even A52S is water proof. What can be the issue? Some time half screen got whita from bottom. Mobile is less than 2 years old. Always in cover with glass protector.
It's seems like display issue but First try to reset your device. And if you're using any external device like memory card, don't use that for few days..
Try to find the cause for glitches, which app is causing it ? Or any pressure on screen, or any task you perform is causing glitches. Many A52s users reported glitches when mobile struggles with low quality signals.
First try to debug cause. It you don't find that, than go to service centre.
