Hey guys new to the site and was hoping I could get some help. I recently replaced the digitizer on my Galaxy Tab 4 7.0 which went well I believed. I used the only available video on YouTube as a reference. Upon replacing the screen and turning it on I thought the screen responded fine. I did a couple of swipe tests to make sure. I then went to play a game and this is where I noticed a problem. In the top quarter of the screen, whenever I was required to hold the screen down the response would jump all over the place. It would register for half a second and I would have to let go and press again to get another touch register. I then noticed the adhesive in the top left corner did not stick all the way. I tried to heat and reset it to no avail. My question is this, is the issue in the actual placement of the glass, the adhesive, or something else? I'm not really to tech savvy as this was my first repair of this kind. Any advice would help. Thanks a lot.
