Hi everyone, I've had the ASUS TF300T tablet for nine days and now the touchscreen has started to not work at times. I've tried to use the cold re-boot but I don't get the writing in the top corner, it just takes a screenshot and then restarts. The problem I'm having is the touchscreen is not working at all. I can't unlock the tablet, use any apps and this is really disappointing seeing as I've had this for nine days. Any help or suggestions would help a lot, thanks.
