Why won't back glass come off?
So basically, my iPhone recently has been having problems charging and the touch screen is a little off so I was going to disassemble is, possibly replace the charging area (I have another iphone that doesn't work for spare parts) and make sure all connectors are in check. But the back glass wont come off. I removed both screws, took out the sim card, and I've watched videos on how it just slides up and out, but when I try to slide it, it's stuck. Won't move at all. Any idea what this could be?
