Tempered glass: how to choose the right one and apply it without bubbl – Accessoryworld

Repairing a broken smartphone screen often costs more than 100 francs. A tempered glass screen protector, on the other hand, costs less than 10 francs and absorbs scratches and minor impacts instead of the screen. You just need to choose the right model and apply it correctly. Here is our simple guide, from choosing to applying.

Why tempered glass instead of a plastic film?

More resistant: a 9H hardness tempered glass protects much better against scratches (keys, coins in your pocket) than a simple film.
It sacrifices itself instead of the screen: in the event of a drop, the glass cracks. You then just need to replace it.
Natural feel: you keep the feel of a real glass screen, without a "plastic" effect.

Choosing the glass for your exact model

This is rule no. 1: the glass must match your phone exactly. An iPhone 15 and an iPhone 15 Pro Max do not have the same screen size, nor do a Galaxy S24 and an S24 FE. If you have any doubt, check our article to find out which phone model you have.

iPhone

Samsung Galaxy

Tip: for many models, the glass is available in a pack of 2. Handy to have a spare glass on hand, or to equip two phones from the same family.

Nintendo Switch Consoles

A portable console screen travels in bags and passes through children's hands: tempered glass is highly recommended. It is available for the Switch, the Switch OLED and the Switch Lite (pack of 2).

Useful Options

Privacy screen protector: the screen remains readable from the front but becomes dark when viewed from the side. Ideal on the train or at the office. Available notably for the iPhone 14 Pro, the 14 Pro Max and the iPhone 13 Pro Max / 14 Plus.
Camera lens protection: on recent iPhones, the camera block protrudes and scratches easily. A small dedicated glass protects it: iPhone 16 / 16 Plus, 16 Pro / 16 Pro Max, 15 / 15 Plus / 14 / 14 Plus, 15 Pro / 15 Pro Max.

Applying Your Tempered Glass Without Bubbles, Step by Step

Choose a dust-free place: the bathroom after a hot shower is ideal, the steam makes the dust settle.
Wash your hands and remove the phone case.
Clean the screen with the provided wet wipe, then dry it with the dry wipe. A screen cleaner helps remove the last traces.
Remove remaining dust with the provided dust sticker, or a piece of adhesive tape.
Remove the protective film from the glass by holding it by the edges, without touching the sticky side.
Align the glass with the cutouts (speaker, front camera) before placing it, then place it in one motion.
Press in the center: the adhesion happens on its own. Push any bubbles towards the edges with a credit card wrapped in a cloth.

Is there still a small bubble? If it is due to air, it often disappears on its own in 24 to 48 hours. If it is dust, gently lift the corner with adhesive tape, remove the dust and put it back.

Case and Tempered Glass: Pay Attention to Compatibility

A case that is too tight on the edges can lift the glass. Always place the glass first, then put the case back and check that the edges of the glass remain flat.
