Review on 📱 [2 Pack] LK Screen Protector and Camera Lens Protector for Samsung Galaxy S20 (6.2 inch), [Positioning Tool] [in-Display Fingerprint Support] – HD Ultra-Thin, Anti-Scratch, Flexible TPU Film by Shawna Lamb

So far I haven't had any issues with this or the tread. Just read and watch the video to make it easier. I had no problems other than a few tiny blisters, but they were gone the next day. It heals itself so great not to have scratched treads while watching videos lol. I don't use a fingerprint scanner, I use Face ID so I can't personally comment on whether this has an impact. But I can say that the sensitivity is not compromised and the camera lens is the best I have ever used! This does not affect the picture quality which I love!
