1, please press and hold the power button to open the options menu, and click "Restart" to restart the tablet. If the options menu cannot be opened, please press and hold the power button until the tablet vibrates, and then release the forced restart.

2. If the third-party application crashes, it may be because the third-party application is incompatible with the tablet. Please restart the tablet, uninstall it, and then download and install other similar applications again.

3. If the crash problem still occurs after restarting, it is recommended to back up important data (third-party applications such as QQ and WeChat need to be backed up separately), and then restore the tablet to factory settings.

4. If you can't operate the tablet after the crash, you can also force the tablet to upgrade.

For the sake of version security, to prevent official website upgrade package from being maliciously attacked, and to provide you with uniform and convenient upgrade service and improve upgrade satisfaction, Huawei will not release the complete SD card upgrade package to official website, but upgrade it online instead. After the upgrade, the data stored in the tablet will be deleted. Please be careful.

If the problem still exists, please back up the data (QQ, WeChat and other third-party applications need to be backed up separately), and bring the purchase invoice and warranty card to the nearby Huawei customer service center for testing.
