Do screen protectors affect touch sensitivity?

Quality tempered glass protectors have negligible impact on touch sensitivity — under 1% difference in our testing. Ultra-thin protectors (0.2mm) have no detectable impact. Thicker protectors (0.5mm) may have barely perceptible delay. Film protectors (TPU) can feel slightly different under the finger but do not reduce sensitivity. If you notice touch sensitivity issues after installing a protector, it is likely a defective protector or trapped air bubbles rather than inherent limitation.

How often should I replace my screen protector?

Replace when you notice: visible scratches that affect readability, edge lifting that collects dust, chips or cracks in the tempered glass, or significant oleophobic coating wear (excessive fingerprints). Typically, a quality screen protector lasts 6-12 months of daily use. With multi-packs (2-3 protectors for $8-10), annual replacement cost is trivial. Replace sooner rather than later — a scratched protector reduces screen clarity and can trap bacteria in cracks.
