Hello guys, my name is Juan Garcia. I replaced the front panel on the iPad mini and it works perfectly fine when up until you lock the screen and then try to unlock it the screen becomes unresponsive. I do a soft reset and the screen works again, until I again lock the screen. Its a new problem thats never happen to me before, please id appreciate any help guys
This is almost always the IC on the digitizer. Replace the digitizer with a known good one and report back.
