Can anyone help me with the problem on Acho c906. It's a Rockchip 2918, 1G ram, 16G storage, 9.7" 4.0.3 ICS. It freezes over constantly, sometimes resulting in garbled image on the screen and sometimes it ever resets itself on it's own once it freezes. This happens maybe every 10 minutes of use. I flashed it with the latest firmware but it makes no difference. Any solution?
