Just check connector of your digitizer again - use magnifying glass and check if all pins are intact ( on both sides - Motherboard and cable). Clean with Alcohol ( not Beer or Whiskey) and carefully make a connection. You should hear and feel CLICK sensation if everything is ok
yesterday my lumia phone touch working very good but… today it cant work…. my phone touch is not damaged or cracked its completly good
