Hi folks, My MI2A appears to have a faulty port. When I plug it in to charge from the mains or a PC the charger flashes off and on constantly. I would then have to re-insert the cable and bend it slightly. I've tried numerous cables and also different charging locations and I'm sure it's the phone. Does anyone know Xiaomi's repair process? I am UK based and bought the phone from China. Any help is greatly appreciated. Thank you!
