My tablet 7.7 went something wrong. It cannot on and be charged.
. I plugged in the charger for three days . Nothing happened at the first two days. But the third morning i woke up, it's fully charged. I don't really know what's the problem with it. And now the battery is flat . I try to charge but it doesn't work .So can any expert teach me what to do. Any help would be greatly appreciated.
