Hi, i have replace my broken front glass with a new one from ebay, not a original Apple glass, it comes with button. After i have carfully mounted it like they show on youtube it would not work, it just slide to sides and open apps, sometime i could touch and it works but after a few sec it lives by itself, open apps and scroll så mutch that it impossible to use it. I cant even turn it off. The glass cost 30 dollar and it came with 3m glue, since the glas had glue under the clear plastic i didnt use the extra glue. I cant understand why it not works after the replacment. Very thankfull for help.
