My tip: Place a hot-water bottle on the screen for 2 minutes. Use the suction handle to lift one edge and insert an opening pick. Use an opening tool to cut through the adhesive at the bottom and place another opening pick in the second corner. Place the hot-water bottle on the phone again and wait 2 minutes. Cut through the sides with the opening tool (if you are focused it's nearly impossible to put this tool in too deep) and do the same on the top of the phone as on the bottom. I was afraid of the high difficulty, but it only took me 15 minutes to remove the screen with no problems. Medium difficulty.
