Samsung Galaxy S23 Ultra Screen Protectors

The Samsung Galaxy S23 Ultra has a 6.8-inch display. That figure is the diagonal measurement, so it doesn't on its own tell you a protector will fit, two devices with the same diagonal can have different corner radii and cutouts. Always buy one listed for the Samsung Galaxy S23 Ultra by name.

Tempered glass is the default choice for the Samsung Galaxy S23 Ultra. The default choice. Rigid, glass-clear, absorbs impact by sacrificing itself.

Worth knowing before you buy: can shatter on a hard corner drop; adds noticeable thickness on curved screens.

It can, and this is the most common complaint in this category. The Samsung Galaxy S23 Ultra reads your fingerprint through the display, so anything thick, heavily tinted, or bonded with liquid adhesive can weaken the signal.

Two practical steps: buy a protector whose listing explicitly states fingerprint-sensor compatibility, and re-register your fingerprints after fitting not relying on the ones enrolled against the bare screen. That second step alone fixes most cases.

Because the Samsung Galaxy S23 Ultra has a curved display and flat tempered glass physically can't sit down onto a curve. The adhesive holds in the middle and the edges bridge, so a corner knock pops it loose.

You've three workable options: a case-friendly protector that deliberately stops short of the curve, a hydrogel film that wraps it, or a UV liquid-adhesive kit that bonds the whole surface. The UV route gives the best result and is also the hardest to fit.

Somewhere between £8 and £25 covers almost everyone. Under about £8 you're usually buying glass with no oleophobic coating, which looks fine for a week and then smears permanently.

Above £25 you're paying for a warranty, a better applicator, or a speciality finish like privacy or paper-feel. Those are real benefits, but they're refinements. The jump in protection from nothing to a £10 protector is far larger than the jump from £10 to £30.

Usually, if you buy one described as case-friendly. Those stop fractionally short of the screen edge so a case lip can sit over the top without catching and peeling it.

Full-coverage and edge-to-edge designs look better but can foul thicker cases. If you already own the case, fit the protector first, then check the case clips down flush before you commit to a second one.
