Every screen protector worth buying,
for the exact thing you own

If your phone is under two years old or you carry it in a pocket with keys, yes — a £10 protector is cheap against a £150+ screen repair. Modern phone glass resists scratches well but still chips on impact.

Glass for impact protection and a screen-like feel; film for curved and folding displays where glass can't sit flat. Glass is the right default for the large majority of flat-screen phones and tablets.

9H refers to the Mohs-adjacent pencil hardness scale, where 9H is the hardest graphite pencil that won't scratch the surface. It's a marketing figure — nearly every tempered-glass protector claims it, and it says nothing about impact resistance.

Fit it in a steamy bathroom after the shower to settle dust, clean with the alcohol wipe then the dry cloth, lift dust with the sticker, align with the frame, and drop it from the middle so the adhesive rolls outwards.

Lift the affected corner with a strip of sticky tape, use a second piece of tape to lift the particle off the display, then lower the protector back down. Don't slide it — lift it.

Almost always one of three things: a curved display that flat glass can't follow, a case lip catching the protector edge, or oil from your fingers having crept under the adhesive perimeter.

Re-register your fingerprints with the protector already fitted. That fixes the majority of cases. If it still fails, the protector is too thick or too heavily tinted for the sensor and needs replacing with one rated for in-display readers.

Three options: a case-friendly protector that stops short of the curve, a hydrogel film that wraps it, or a UV liquid-adhesive glass kit that bonds edge to edge. Flat tempered glass doesn't work on a curve.
