My digitizer on my Acer Iconia W5 becomes unresponsive sometimes while in use. Resetting the tablet doesn't work and I have to remove the back cover and disconnect the battery to get it working again. It's been happening more and more often. I don't think it is the digitizer itself because in other forums people report it becoming faulty on a certain side of the screen, because it is cracked or having to exert a lot of pressure but, definitely not being able to be reset by the battery. Also the OS itself and all the programs seem to remain stable in the background while the digitizer remains unresponsive.
