I have had Mobicel Zoom tablet now only 6 months - working fine no problems but it just turns off by it self with out any warning - it still has lots battery power - the only way to get it started is to plug in charger - when I plug in to charge it shows like 80% battery power left - I have to restart and it then works - until it just go off again - and the whole process start over - I cannot work with it and it just go blank all the time
