Tempered glass or hydrogel film — what is the difference?

Tempered glass (9H hardness) protects against drops and scratches and feels like the real screen under your finger. Hydrogel film is thinner and flexible, sits properly on a curved screen and heals surface scratches by itself — but it does not absorb impact. For most phones we recommend tempered glass.

Does a screen protector make the display worse?

No. A good protector has over 99% light transmission and an oleophobic coating that repels fingerprints. Colours and brightness stay the same.

Will a protector interfere with the fingerprint reader?

Tempered glass can slow down an in-display reader slightly. Hydrogel film works better with that technology. Tip: re-register your fingerprints after fitting the protector.

How often should a screen protector be replaced?

Replace it as soon as you see cracks or deep scratches — a cracked protector no longer protects properly. A good one typically lasts 6–12 months.

Description

Crong 3D Armor Glass is a model-specific 0.33 mm 9H tempered-glass screen protector for iPhone 17e / 16e / 14 / 13 / 13 Pro. A black 2.5D edge follows the rounded display outline, while full-surface adhesive supports even contact and responsive touch control across the usable screen area.

The manufacturer states that the glass is four times stronger than ordinary glass and transmits 92% of light; these are product test claims, and the screen can still break. A shatter-resistant layer helps retain sharp fragments if the protector is damaged, while an oleophobic surface reduces fingerprints and supports smooth finger movement. The included alignment frame and cleaning accessories simplify installation. Check the clearance of a separate case, even though the protector is designed to fit most cases.
