I had my screen replaced today by an ifixit authorizes dealer and my phone is freezing up as well as lagging and my 3D Touch does not work. My home button is lose as well. Also, the colors at the top are lighter and just diferen overall. LCD and screen were both replaced. Anyone else have this issue?
It’s a defective screen. iFixit doesn’t have service centers for repairing phones they just sell parts. My advice is to take the phone to where you got it repaired from for warranty on screen.
