So I just got myself a Zenpad S 8.0 (Z580CA). I updated the software to the newest 6.0, that I downloaded from the original website. The porblem is whenever I leave my tablet in sleep mode (aka not using it) for a while, I have to press the power button 5-8 times to wake it up once... Otherwise the tablet is functioning perfect, but it's very annoying. Does anyone has a solution? I tried factory reset but it didn't help at all.
