Review on OMOTON [3 Pack] Tempered Glass Screen Protector for Samsung Galaxy Tab S6 / Tab S5e 10.5 inch - Scratch Resistant & Enhanced Protection by Justin Buck

I've installed screen protectors on dozens of devices, so I'm familiar with the procedure. Cloth and thick cardboard to smooth bubbles. This package was missing a dry cloth and cardboard float, so I grabbed them from the screen protector that was last installed. I followed the procedure and found a raised spot as if something was stuck under the protective film. I removed it and cleaned the tablet again, but the stain was still there. So I tried again with the second protector and encountered the same problem. I finally tried the 3rd protector and faced the same problem again. That's when I noticed that the stain was in the same place on all three screen protectors. It was obviously a defect in the protective film. After all, the most important reason why you should not buy this product is that it blocks the fingerprint sensor! How to make the protective film of the blocks one of the main features of the tablet?
