Steps to reproduce:
- Close the lid, wait for the green LED light to go off
- Plug into charger to charge Miyoo Flip (Green and Orange LED both turn on)
- Wait one minute
- Unplug Miyoo Flip from charger
- Open the device
After performing the above steps, the battery status icon will be stuck in charging mode (with the lightning sign in the middle), and it will stay this way until a reboot. Both green and orange LED will stay on, even after closing the lid or pressing the power button to turn off screen. I suspect that the device no longer goes into sleep after this.
