i have a big problem with my Tablet WM8850

[smilex93]

i dont know how i fix the many problems with my tablet :


the first one is. when i plug AC cable the tablet is turning automatic on, and the battery status is 100% when i plug the cable off at the home screen, in 3 seconds it shows 0% and the tablet is going off

the second one is, when I touch the touchscreen, but the position is somewhere else. and he is scrolling reverse xDD and when i clicking on the settings button he is clicking somewhere. what the hell ?! xDD

the third one is the sound, its simple problem, he is not playing sound

i think the firmware is broken

i have buyed the tablet here :
7" VIA WM8850 1,6GHz Dual Core Android 4.0.3 Tablet PC 4 GB Cortex A9 WiFi/3G | eBay

I'll be honest, if you just recently bought it and haven't done any modifications, I would just return it and get a replacement or refund. It sounds as if you may have got a lemon.

i would hate for that to be the case, so to be sure try flashing the firmware. read through my thread to learn how
http://www.androidtablets.net/forum/wondermedia-based/50114-wm8850-mid-firmware-update-root.html

one way to know for sure is if there is actually software that will automatically shut down your tablet when it reads 0% on the battery, if not, then its hardware fault and your device is broked

on there the w70 firmware is there. install it through nand with it on the sd card and see if it works. afterwards if it works do the touch callibration. let me know. that firmware there should fix it. after that you can use the fwc file there and put any rom in
