I have searched for any other topics re this problem and haven't found any.
I've already had to return my Scroll because of a major board fail some 6 weeks after purchasing it and now, some 6 weeks after that repair, I've another problem.
The battery indicator is constantly moving from empty to full, despite the unit being charged up overnight. Sometimes, when it shows empty, it switches itself off. Other times it keeps moving as if it was still attached to the charger and charging, which it isn't.
I've tried factory reset and I've tried usb charging with no change.
I'm hoping there is a fix out there otherwise I shall be demanding a refund!
