Hi guys, my zenithink c71 ZT280 is 2 days old, its been ok but today the speaker stopped working. It all started when i decided to use some headphones. the speaker does work but is barely audiable. headphones work fine. ive reset the device which made no difference, ive factory reset it too. ive checked all the volume levels even used android assist with no luck. I'm about to smash this tablet with a hammer and give up.. anyone got any suggestions? is this a ICS issue or a hardware issue? I'm starting to think i should have just bought a google nexus. also it wont boot with a TF card inserted.
