Hi did you fix the broken screen yourself or you went to a repair shop?, if you fix it yourself then i would suggest you disassemble your phone, disconnect and reconnect your lcd and touch panel cable, it could be improper connecting of lcd able ribbon that cause this issue, if you went to a repair shop then i would suggest that you return back to the shop and ask for assistance, hope that helps cheers, and alos it could be a case of a faulty lcd and touch panel due to manufacturing defect, so try the above first before trying another lcd and touch panel, cheers!
