Review on 📸 Pack of 3 Tempered Glass Screen Protector for GoPro Hero 4 Session and Hero 5 Session - Akwox 0.3mm 9H Hard Scratch-Resistant Camera Lens Film for GoPro Hero4 Session/Hero5 Session - Camera Accessories Bundle by Marc Gallner

Works very well but the sticker on the back (sticky side of the screen) says 'Front'. So I left the lid open so I wouldn't leave fingerprints on the front during installation. Because of this I tried putting it on upside down without understanding how a friction fit screen might work. It wasn't until I removed the sticker that I realized it was protecting the sticky side that was meant to be pressed against the device's screen (as you initially suspected). Obviously not a big deal but I messed up two of them trying to clean the 'front' of the screen, messing up the sticky surface and obviously damaging the side you don't want any dirt on at all.
