Johncase[2 Pack Screen Protector Compatible for Samsung Galaxy S8/S9, Full Edge 3D Curved Tempered Glass Film W/UV Liquid Adhesive Light Installation Kit [Case Friendly]

The seller is excellent, provides fantastic customer service. Unfortunately their initial instructions that did not make it clear that you needed to cover up all the ports on your phone, the speaker port, the earphone jack, charging port, the mic port, etc., , and any other openings with some sort of a tape, before applying the UV glue.My first experience was not good. I followed the initial instructions to the t, but I found that the glue when applied as shown started to pool towards one end of the phone. This was due because my counter top was not perfectly level. I lifted the phone a bit to level it and waited for the glue to center. I then placed the glass protector on it and watched as the glue spread, I did not touch it, but the glue seeped out of the edge of the protector and covered the top, bottom and sides of my phone!! It was also dripping all.over the counter, and could not stop it. It filled up the ear speaker and all the ports. I wiped it off with a paper towel, but did not realize it has flowed into the ports. When I turned on phone I could barely hear out of it even on full volume and the charging port did not work.I was panicked but fortunately I was able to fix this problem by turning off phone, then taking a toothbrush and soaking it into rubbing alcohol and scrubbing all the ports, speaker ports, earphone jack, charging port, then blowing them out with compressed air. I repeated several times until everything started working again. Warning: make sure if you do install this with phone off. I have not installed another cover as of yet, though the seller did refund my money and provide me another cover. I will attempt to install another cover one more time but this time I will make sure I cover all the ports and put my phone on a plate but lift the phone off the plate so that when the UV glue flows all over, it will drip off the phone and onto plate not counter. Before you cure it with uv light carefully wipe 9ff excess. I will update my review after I try this again. Hopefully this time it will install with our issues.

I must say this is the best screen protector tempered glass I've used until now!Absolutely different with the regular old tempered glasses those are not the full coverage and also not so clear and duableBut this one gave me deep impression and even if changed my mind to tempered glass- Super super clear and transparent like crystal or diamond- Full coverage rounded edge to edge- Zero bubble- Duarable ( 2 days ago, my phone dropped to ground but the screen was ok, also the tempered glass was also no broken, so this tempered glass did the job, thanks)- High touch sensitivity- Super super beautiful even if you can't feel any glass protector on the screen- Price is also so nice for 2pcs high quality UV liquid glassWarm tips:since this is the UV liquid tempered glass, different installation as normal ones, before installing it, highly recommend you to read guide installation and video, so can help you to install properly ( Becsuse i had installation failure for my 1st one, but what a luck, this seller offered 2pcs, then i read guide installation and videos few times and follow to do step by step, actually it was super easy! I finished my 2nd one super perfect)Especially need to note:1. Must keep your phone on a leveled desk, otherwise the glue flow to the end of phone and mess up ( like flow into the charging port or ear speaker, that's terrible! Oh, I forget to say before installing, use the guide stick to put on the ear speaker and charging port to avoid glue spilling)2. Don't install it under the sunshines or closed to window( the best place is indoor, because under sunshines, the UV glue easy to dry and glue can't cover the entire screen)3. Don't move or lift or press glass while the glue fitting automatically, very very important4. Don't forget to use the UV light to dry the glue above 60 seconds ( For all of corners and edges, dry above 120 seconds again, in that case, the glue fit the screen better and not easy to peel off)Hope my experiences can help you to install better and avoid waste money and time!I've shared this UV glue tempered glass on my facebook/instagram and Youtube and let more friends know this best screen protector!If you are looking for the best screen protector for your S8 or S9, this one is your 1st choice!!!

These are really nice screen protectors. Full coverage edge to edge to protect my phone so great! 2 days ago i was walking and i lost grip of my phone and it fell face first onto the street. My screen ended up hitting 3 rocks. I know this, because the two top corners of the screen were chipped and cracked and the middle of My screen had a chip it. But the only thing that was damaged was the screen protector! My phone screen was safe with no signs of any damage!Now i am installing the 2nd this UV liquid tempered glass (because the seller offered 2 pack for this nice price)I really love this UV liquid tempered glass, definitely different from other normal regular tempered glass!1. Full coverage edge to edge2. Super high clarity it seems you can't feel the screen protector on your phone3. High touch sensitivity4. Fit the screen so good and not easy to peel off after compatible with caseSince This was My 2nd time to install UV liquid tempered glass, I have experience to share with new buyers as below:1. Before installing, suggest you to read guide installation and video to know each step2. Must keep your phone on a flat table, otherwise the liquid flow to anywhere3. Dont install under sunshines ( install indoor better much,because the UV glue is easy to dry under the ultraviolet rays)4. Dont move/lift/press glass when the glue Fit it automatically5. Remember to use UV light to irridate all of edges and corner above 120 seconds and let the glue Fit better the edges and corners more solid and not easy to peel offIn future i only use the UV liquid glue tempered glass! My favorite now!
