I'm sorry about the issue. Can you please press and hold the Power on/off button on your ereader device for about 45 (to 60) seconds this time, then turn it back on and check?
- If needed, charge your device for about half an hour. Then while charging the device, hold the power on/off button for a minute again, then turn it back on and check.
- If there is still any issue, please let me know the model of your device.
When you are available, please reply at the box below to continue troubleshooting. Thank you.
