As we all know , when we refurbish a iphone 7 LCD , the backligh allways have some problem, we have to change the backlight, but if we change all iphone 7 backlight with 3D touch that will be so expensive. we know the old original 3D touch is good. Take the iphone 7 backlight without 3D touch is your best Choice ! remove the old backlight only and put our backlight on orignal 3D touch panel is ok ! easy operate and save your money!!
