So I am not to sure how to describe the issue I am having so I am attaching some images. I have a contract with my schoolboard to complete all of their ipad repairs. I have enever had any issues at all with ipads but with these I am. It almost seems like there are 2 peices of glass glued together and they are seperating or something.
It looks like the glue under the glass screen ontop of the digitilzer is coming off. You may have bought cheap replacement screens or it could be placed under heat. To fix this you will have to remove the glass take all the glue off and replace it using uv glue but this is really difficult you will e probably end up breaking the glass or digitlizer unless you are skilled and have tried the repair before
