Brought in my iPhone to get the screen replaced after I dropped it out of my pocket and the screen went dark. Thought I would save money here -$ 100 dollars as opposed to $ 135 at the Apple Store– but the replacement screen was not done correctly. The touch is not working now — the screen freezes and it thinks I am touch one part of the screen when I am touching another part– which it worked fine before even with my darkened screen which I had for 2 weeks before bringing it in. I brought it back to the store to fix it and they told me that they ‘calibrated’ it and if it still isn’t working correctly it is the ‘brain’ and that I would have to take it to the Apple Store to fix that! Wish I had just gone to the Apple Store in the 1st place.
