HERE IS THE LOGICAL ANSWER After reading through all post I still could not find the right fix, A lot of the post on the right track but explaining it kind of wrong, The easiest solution Is to go back to the old screen at the bottom where the Home button is located, There you will see two pieces of fabric tape, The one closest to the home button will be layered over a clear piece of tape, try to remove them together, use x acto knife to lift up corner, then a good pair of tweezers to peel it off. Perform the same procedure To the fabric tape to the left, Then place both pieces down on your new digitizer, In the same place that they were in on the original. This should solve your problem 100%. iPad Mini is a very very difficult repair, And I have done many, There's always a problem I learn every day.......Cheers! *Attached is a image of the area you need to be working in, I had already removed the fabric tape before posting this, but I have outlined the areas as best as I could*
