When the phone appears to freeze or hang,  please follow the troubleshooting steps listed below:

- Freezing in Standby
If the device freezes and doesn't respond to the touch, please back up all data, clear the cache and flash to the latest OS version.

- Freezing in third-party Apps
Please check whether the issue occurs in a single third-party App or other third-party Apps as well.

1. If the issue occurs in one third-party App, please uninstall the responsible third-party App, clear your cache and check the latest update.
2. If the issue occurs with other third-party Apps, make sure the app is compatible with the latest Android version. Try uninstalling all responsible third-party Apps, clear the cache, back up all of your data and flash back to the latest official version of OS.

Freezing while loading Apps
Please back up all your data, clear the cache, uninstall the latest update(Enter into Setting--Apps--All to view), finally restore the factory settings or flash back to the official latest OS version.

If the steps above did not solve the issue, we recommend applying for after-sales service.
