I just sent a support ticket last night and am still waiting to hear back.
EDIT: Hmm, strange… I left the tablet charging last night and it was at full charge this morning, and I tried turning it on again and today it turns on normally. It doesn’t seem like the battery should have been depleted when I tried it last night, and I also tried turning in on while plugged in last night, to no avail. I’m guessing GearBest probably won’t get back to me until Monday since we have a weekend coming up, so I guess I’ll play around with it the next few days and see what happens. Will report back with my findings.
