How to protect a phone screen
A case with a raised lip and a screen protector you actually leave on will prevent more repairs than any setting.
Most cracked screens we see were in a pocket with keys, or on a table edge. A case that stands proud of the glass helps. So does not sitting on the phone.
If the glass is already damaged, a protector will not fix the picture. iPhone repair and Samsung repair both start with the exact model.
