Hi guys n gals. Just had my first ever android tech deliverd yesterday, a ztpad zt280 c91 upgrade. The bumf on the net says it has bluetooth, i can find the bluetooth switch but when i try to turn it on the on icon lights up and goes straight back to off again?. I've tried other switches wifi etc and they all work fine, do i need to alter a setting somewhere else on the tablet before bluetooth will turn on?. Tablet was fully charged when deliverd so played for a while, but found when i came to charge it they had sent the wrong charger, i've got one for a zt102!,very frustrating, have emailed them and are being sent a replacement[ from china!] have checked other chargers i have but none will fit. Anyway as i'm a bit of a novice i will no dought need some advice in the future, so hope i can call on you?. any suggestions wuold be appretiated. Regards Mike.
