Been working fine for about a year and 2 months after that started suffering from flickering which only occurred when there was no motion on the display. Short fix was to set up seconds timer on the sidebar but that soon came to be not enough and the flickering increased in volume.
Freezing of the device would help for short time but it finally came to the state where nothing works and the only way to use the device is to cast the screen through minidisplay port to another monitor which basically kills the portable function of the device....
