Review on 📱 High-impact Protection for Samsung Galaxy A20 - 3-Pack Tempered Glass Screen Protector [9H Hardness] [Lifetime Replacement] by Mr. Shield by Adan Hudson

Good even round edges (ie no shape but an edge, not sharp). Goes on easily, can even be peeled off with a fingernail to adjust if you screw up. With all protectors there is always a chance of dust getting in, even with sticky dust, cloths etc. It's in the air. I had 1 or 2 dusts on each phone which is not a big deal. Bubbles aren't a problem, except for a small amount on one phone's edge, which again isn't very noticeable when the phone is on. There were big bubbles in the middle, so just use your fingernail to lift the protector halfway, then slowly lower it in one direction.
