The operation of the phone with this screen is not satisfactory: the screen only works when the card is disabled, a few minutes or tens of seconds after activating the screen freezes. It is then necessary to remove the battery to restart the phone. In looking more ready, the component that manages the touch screen is not the mark of origin (instead of ChipOne SYNAPTICS) and there is no shielding on the circuit. This replacement part must either be withdrawn from sale or sold with the word 'part not original - not guarantee operation'.
