Review on 📱 amFilm 2-Pack Screen Protector for Samsung Galaxy S21 5G 6.2 inch (2021) - Fingerprint ID Compatible, HD Clear, Scratch Resistant Hybrid, Case Friendly - Easy Installation Tray Included by Phil Casey

I didn't succeed in attaching the film protection, but I didn't want a glass protection film on the S21 ultrasonic fingerprint sensor, at best they come across. The package contained everything needed for a smooth and easy installation: the instructions were simple and legible, the sealed velcro for cleaning/drying and dusting was in an extra sealed bag to ensure they didn't dry out. The tread and air bubble removal squeegee is well designed and efficient. I put my S21 on a non-slip surface, attached the Wet/Dry/Dusty sticker - placed the guide frame on the phone - removed the #1 tab on the tread, gently insert it into the bottom guide pins and then the top guide pins, then press the protective film firmly onto the phone, lightly flatten a bubble or two, remove the top foil cover and finish, flatten the ends and remove a few small bubbles at the ends. I spent about 5 minutes total on this, resulting in a perfectly aligned (top, bottom and sides) bubble free build. I enabled the S21's screen sensitivity to protect the screen. That's all! The ultrasound reader works just as easily as before (I didn't have to reposition my fingers). The screen feels fairly smooth, slightly smaller than before but barely noticeable, and screen sharpness is excellent. I use this with a Spigen Rugged Armor case - no problem. I can't say anything about the durability, should there be any problems,
