iPad 4 after Digitizer replacement some areas don´t react
i replaced my iPad 4 front panel after it was broken but now i have the problem that the new digitizer only reacts at the top and bottom area, in the middle of the screen it doesn't response. I thought the Digitizer is damaged so i took a new one but same problem only in different areas.
What can it be? Is it again maybe a damaged digitizer or maybe a short circuit some where or something else?
Really appreciate if you can help me out.
Is this a good question?
