Review on TOCOL 6 Pack for Samsung Galaxy S21 5G 6.2 inch - Tempered Glass Screen Protector & Camera Lens Protector with Installation Frame - HD Clear, Bubble-Free, Case Friendly (3 Pack Each) by Robert Cole

I often apply protective films at work, so I quickly learned how to use them. It was a little tricky because the S21 has a few "landmarks" to line up by, but I managed. Got a good install which was a relief based on my experience with other Samsung phones. Looks like the S21 is flatter than them! There's some air in the bottom right corner, but I'm more inclined to blame Samsung's curved glass than screen protectors. This is significantly better than the iPhone 8s or SE. As you can see in the video, the fingerprint sensor works fine (double tap was the result of looking at my camera) and I didn't need to increase the touch sensitivity.
