I cleaned my phone with anti static cloth and ensured it was dust free. I followed the instructions, there are 2 protective film layers, tab 1 and 2,. Tab 1 protects the adhesive face and tab 2 is only removed when the screen protector is applied to your satisfaction (lol), it tells you to line up from the top of the phone which is frankly stupid as it has a cutout for raised buttons at the bottom of the phone and lining this up first would make more sense and the simple process much easier, but I followed the instructions anyway. this resulted in lots of bubbles which even with the provided tool don't push out and also seemed to mark the surface, if you try to reposition it at all, poor adhesion becomes no adhesion, removed tab 2 easily but noticed the smoothing out tool had left marks, wasted screen protector, have not bothered with the remaining 5 that are left.
I am now looking for alternatives.
