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.

Crong 3D Armour Glass Lite full-adhesive...

Description

Crong 3D Armour Glass Lite is a 0.33 mm tempered-glass screen protector shaped for Samsung Galaxy A16 / A17 / A26. Its Full Glue adhesive covers the entire underside, while the black frame and Edge-to-Edge format follow the display area. The 2.5D edge profile is designed to sit smoothly around the perimeter. Crong specifies 9H surface hardness, 92% light transmission and a Shatter-Resistant backing layer that helps hold fragments together. These are construction specifications, not a guarantee against breakage of the protector or phone screen.

Before fitting, remove the case and clean the display with the supplied wet wipe. Dry it with the microfiber cloth and lift remaining dust with the dust-removal sticker. Align the openings and edges, lower the protector carefully, then press the centre so the adhesive can spread. Refit a case only if it does not lift the protector's edges.

Compatibility: Samsung Galaxy A16 / A17 / A26
Thickness: 0.33 mm; black frame and 2.5D edges
Full Glue adhesive; 9H manufacturer hardness specification
Included: one protector, wet wipe, microfiber cloth and dust-removal sticker
