I've had my Spigen tempered glass for about 3 weeks on this G3 and today it formed a number randomly on the side of the screen. It's not touching the outside (meaning it didn't break the seal) and there is absolutely no dust or dirt under it. The bubble wont go away and has gotten slightly bigger. I tried running a lot games to heat the phone up to see if it would re-adhere, however it would bit, I also tried pushing it down/our using a card and microfiber cloth. I've had many Spigen tempered glass when protectors before, but I haven't seen this issue pop up. It's unfortunate, and I really don't want to return it to amazon or exchange it and go through the hassle of another perfect installation. It should be noted that my phone did not over heat at all, I didn't drop it or do anything to cause this. It just showed up. Any ideas?
