Johncase[2 Pack Screen Protector Compatible for Samsung Galaxy S21 Ultra, [Supports Fingerprint Sensor ID] Full Coverage 3D Curved Tempered Glass Film W/UV Liquid Adhesive Light [Case Friendly]

No instructions in English! Or even illustrated

I purchased this screen protector because it was pointed out in the product description that the fingerprint sensor works perfectly. This protector is NOT fingerprint friendly!! Disappointed! Other than that, installation was fairly easy and the other touch functions work pretty well. Still searching for a fingerprint friendly glass.

This product isn't for the first timer.. it requires some experience.If you've installed these before without a guide, this is for you.I recommend getting one of those tiny levels to make sure the surface you're doing this on is just right.Also, I've read other comments saying it's messy.. I disagree. On the contrary it's the least messy installation I've ever had. The glue doesn't really spill over the edges like other options.Lastly.. you can't beat it for the price! $12.99 for 2? Come on now. This product is better than others that cost 3 times as much.

Glued the buttons both times I installed, even after using tape the second time to avoid the glue seeping in them. Still have stuck buttons... Hoping time will release them after hours of rubbing with alcohol.Messy! Even if done to get all air bubbles out and to get the correct lay before treating under uv (which I used my own nail salon light)Glass and protector seem to work okay despite my issues with install. Butt not worth the glued buttons which almost factory reset my phone.

Complete of junk- first this UV is on a very short cord,not battery like most. 2nd no directions- complete mess. 3rd the glass was damaged. When it came out of the package my husband asked me if that was a spot on the inside glass. I said no it has to be on the outside. WRONG it was on the backside. So now after this mess and giant pain I have to get another one. Don't by this -- just don't do it

Gave me a broken light with product everything else is fine installed it but no uv light to heat the glue

Horrible the tubes feels like it doesn't work worst purchase

So the screen protector is easy to install no bubbles and perfect. I was quite excited. I think people just are not used to it and don't know how to do it. I've done probably 50+ UV protectors in my life. Anyway the only negative thing that makes me sad about this protector and ready to find another and remove is...... it's a finger print magnet. It says in the description oilephoic coating and resists finger prints. This actually gets more fingerprints than any protector I've ever used. And I hate them!! So I am unsatisfied!
