the instructions below:

optimal operation.
• Avoid storing large amounts of data in your device as this
may affect its performance.
• Use Erase all data and the upgrade tool to perform
device formatting or software upgrading. ALL User device
data: contacts, photos, messages and files, downloaded
applications will be lost permanently. It is strongly advised
to fully backup the device data and profile via Android
Manager before doing formatting and upgrading.
My device cannot be switched on or is frozen
• When the device cannot be switched on, charge for at least
20 minutes to ensure the minimum battery power needed,
then try to switch on again.
• When the device falls into a loop during power on-off
animation and the user interface cannot be accessed, long
press the Power/Lock key and then long press Power off
option to enter Safe Mode. This eliminates any abnormal
OS booting issues caused by 3rd party apps.
• If neither method is effective, please format the tablet by
pressing the Power/Lock key and Volume up key at the
same time when device is powered off.

Lock key.

reboot.
