I watched a Hugh Jeffreys repair video on one of these iPads today. He recommends not trying to replace housings or smart connectors on this model. Apple's level of greediness recently locking parts to phones and making other parts impossible to remove is going to bite them back one day.
Samsung are evil for creating the phone like this. Having to remove the screen to replace the charging port is just a bad design choice. Luckily they sorted it out later on and now the charging port on later Samsung phones comes out on its own. The screen will almost certainly be damaged or even destroyed during this repair.
