Most likely you didn't properly repaired the device the correct way. That usually happens when you replace the glass and don't bond it with oca (optical clear adhesive) or loca (liquid optical clear adhesive). I've use to do this, when I first started repairing phones. Now I use loca to bond them, making every repair look just coming out the manufacturer as possible.
