New screen won't stick to frame
Samsung adhesive usually works flawlessly, but for some reason the pre-applied adhesive on the Alpha screen is terrible and doesn't stick at all. I removed the original adhesive and applied our own which is super strong and works great with everything else - not on the Alpha though! Still loosens in the corners. Not as much, but still a lot. Thinking of using strong liquid glue instead.
I have cleaned the frame thoroughly, so that isn't the problem. Also heated the phone with attached screen and pressed it afterwards over night.
Seems like the surface of the screen itself isn't very prone to sticking.
