How to use

Clean the Galaxy S21+ screen thoroughly with the included cleaning wipe and dry with a lint-free cloth. Use the provided dust removal sticker to eliminate any remaining particles. Align the protector with the phone’s display edges and gently place it onto the screen, allowing the adhesive to spread from the center outward. If small air bubbles appear, press them toward the nearest edge using a soft card or the applicator supplied with the kit until they dissipate. Ensure full adhesion before returning the device to regular use.

Usage recommendations

For best results, apply the protector in a dust-free environment at moderate temperature and re-clean the screen if necessary before installation. Replace the protector if it sustains deep chips or cracks to maintain maximum display protection and touch performance.
