7. Troubleshooting
7.1 App doesn’t respond, or crashes
If some app does not respond to some operations, you should wait. If
no response even after the waiting, you can close the app and open it
again.
If a dialogue box for error pops up, you should select compulsory
shut-off or wait. If no response even after the waiting, you can select
compulsory shut-off again.
If the app can’t be closed, you can click the button Home and open
ES Task Manager, and then eliminate the app.
If when the app crashes, you fail to open it after it is eliminated through
ES Task Manager, you should reboot the system.
7.2 System crashed
If the system crashes, operations in all interfaces will become ineffective.
In this case, you should power off the device or reset it.
7.3 Factory defaults
If your product runs extremely slow, you can restore the factory defaults.
Remember to backup the data before restoration, for it will delete the
Google account, data of system and its apps and the downloaded apps.
