I have an A13 Allwinner tablet. Its own ROM was laggy. I found a similar ROM from another tablet comapny and flash it with. It was fine and everything worked perfectly.
Now there is a newer version (4.0.4) of said ROM. I flashed the tablet with the new one and Camera and G Sensor doesn't work.
I am asking if there is a way to FIND the respective drivers and HOW to apply them.
I have bought a tablet from China, and now I have installed the Ubuntu (14.04) OS to that device (was previously Windows 8.1). I faced some issues with the device's touch panel, bluetooth, WiFi, cameras and audio drivers... Can anyone give any advices how I can get them work properly?
