Why is my tempered glass lifting from the corners?

You install a screen guard perfectly, only for one of the corners to start lifting up a day later. Why does this happen?

The main causes are: * **Micro-dust**: A tiny speck of dust near the edge blocks the adhesive from making contact. * **Case Push**: The lip of your phone cover wraps too far around the screen frame, pushing against the glass edges. * **Curvature mismatch**: Minor dimensional deviations on the phone's glass border.

Choose a case-friendly tempered glass that leaves a 0.5mm margin at the edges to ensure complete compatibility.
