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 Joshua Cameron

Not to mention shaky hands during installation, this is an amazing screen protector that I would buy again and recommend to a friend. After aligning with the tool and gently dropping the tread, the adhesive spread evenly on its own leaving barely visible bubbles on the outside edges that were very easy to remove with some pressure from my thumb. The result is a clean installation. The polished 2D rounded edges help hide the screen protector while keeping my Galaxy S21 looking good, unlike some other brands' 90 degree cuts. I didn't register my fingerprints until installation and they were quickly removed. The phone has fingerprint verification, so you don't have to wait until it's locked to see if the fingerprint is correct. Use a check to ensure your print goes through the glass well. Mine made the first try and opens the phone every time, almost always on the first scan and rarely takes longer. I'd say it's about as accurate as my old Note 9's rear dedicated scanner; although the S21 needs more pressure. Works with Otterbox Defender and does not touch the case.
