Know before you buy
While this tempered glass is designed for high responsiveness, adding any screen protector can sometimes affect the sensitivity of ultrasonic fingerprint scanners. You may need to re-register your fingerprints after installation or increase the touch sensitivity setting in your phone's display menu for optimal performance.
Each retail package includes two tempered glass screen protectors, giving you a spare in case of an installation error or future damage.
The 2.5D rounded edges are designed to be case-friendly, meaning they shouldn't lift or bubble when you snap on most standard protective phone cases. However, extremely bulky or heavy-duty cases that wrap tightly around the front glass might still cause interference.
The installation is straightforward and uses a dry application method. Because the adhesive is designed to be bubble-free, it adheres smoothly on its own once aligned, though taking your time to clean the screen thoroughly beforehand is the most important step for a perfect finish.
The coating is quite effective at repelling natural oils and sweat, which helps keep the screen looking cleaner throughout the day. While it won't prevent fingerprints entirely, it makes them significantly easier to wipe away with a quick polish.
