How to apply a screen protector without bubbles
Follow a calm, dust-free process for straight alignment and a smooth result.
Most bubbles come from dust, poor alignment or working too quickly. A clean space and fixed order greatly improve the result.
Prepare the space
Work on a clean, stable surface with good lighting. Wash and dry your hands and arrange every tool before starting.
Remove all dust
Use the cleaning wipe and dry with microfibre. Lift the last particles with the dust sticker without touching the display again.
Align first, then lower
Use the speaker, edges and camera as reference points. Hold the glass by its sides and let it bond slowly from one end.
Deal with bubbles
Push ordinary air towards the nearest edge with a soft cloth. A persistent dot is probably dust; lift only that local area carefully.
Frequently asked questions
How long do small bubbles take to disappear?
Very small air patches may reduce within a day; bubbles caused by dust usually remain.
Should I remove the case first?
Yes. Install the glass first, then check that the case does not press against any edge.
