I just joined this forum recently because Iím having problems withmy Android tablet.
I purchased a Zenithink ZT280 C91 tablet in April and latelythe speakers have started making a hissing noise even when the tablet is onmute. I upgraded the firmware to the latest version (4.0_0818_V1.42) which Idownloaded from the Zenithink site but the problem is still there.
Can anyone help me with this problem?
If I want to wipe the tablet completely and reinstall the latest operatingsystem does anyone know how to do this and where I can download the entire os?
