I've seen a few people now, including myself, who have had more trouble than usual getting the Spigen protector installed without getting stuff under it! The one I have on now (4th Spigen one!) has a tiny hair towards the top, left of the camera. It isn't making a bubble so I can cope with it there.
The JETech ones appear to have a black border around the edges. Are you using this protector with a case? Which case if so?
I'm using the Spigen with a Spigen case at the moment and there is very little room for the protector to be longer without it touching the case, but there is room on the sides if those black bits extend outwards a bit.
Lint and hairs collect like no ones business around the edges of my Spigen protector, which is really annoying! Hoping it'll stop doing it once the edges of the protector lose their "stick".
