My screen broke while removal, but no issues aside from that. No fault of the review, just be very careful if you are hoping to reuse the screen. They’re cheap on Amazon, just plan on breaking it unless you’re a pro.
My only recommendation regarding the directions is to really heat the screen up. I progressively heated it hotter and hotter and found that the adhesive really loosened up when an IR thermometer showed the screen to be ~190 F, which is in my opinion a higher than the guides recommended ‘slightly too hot to touch’.
Also, be careful to not get alcohol on the foam under screen liner - it will badly melt it and will make your screen sit wavy.
I found better luck with a wide, flat razor blade to make the initial gap. Be sure to go in at an angle rather than straight down, I went too far down and bent the mid-frame a little bit. A wide blade won’t scratch up the phone frame. But at this point my screen was already broken so take that for what it’s worth.
Isopropyl Alcohol will damage the foam padding if you aren’t careful - the pad will dissolve away.
