Hi, After falling on the road my Mi4's screen is broken and touchsreen doesn't repond anymore. I plan to buy this kit: http://www.dragon-tt.com/xx.aspx?id=2661. And then to go to a repair shop with it and ask them to make the replacement. Question: 1) Since Xiaomi is mostly unknown in the UK, can repair shops still make such replacement if provided with the right components? 2) Are all Mi4 screen/digitizers equal, or does quality vary? Is it possible, for instance, that the one I linked could be less good than my original (broken) one? 3) Same question with housing: http://www.dragon-tt.com/xx.aspx?id=2659#. Same quality as original?
