Touch doesn't work after I tape screen to device
I have had an issue with the past two iPad Mini devices I have repaired. The touch on the screen works great I test it before closing the iPad and after I close the iPad the touch doesn't work anymore. It starts touching apps on it's own and goes crazy. I have tried 3 different screens and two different iPads and I get the same issue. Anyone have any idea what I am doing wrong?
I put some tape over the connection where the digitizer flex connects to the IC chip, but that didn't help either.
Please does anyone have any solution I can try?
Thank you so much
