Click Application Management in the entered page. On the application management page. Click on the logo in the upper right corner. A pop-up window will pop up. Click to display system processes. In the display system flow page. Find a healthy way to use your mobile phone. You can also display the search bar at the top of the system progress page. Enter the mobile phone for healthy use.
Find a healthy mobile phone and click Enter. Click Save in the entered page. Then select Clear Data and Clear Cache. After completing the above steps.
The mobile phone usage record in the healthy mobile phone was deleted. If the mobile phone usage record cannot be deleted after completing the above steps. Then there is nothing we can do. That means this is the system and data of Huawei mobile phone. Cannot delete. Mobile phone usage records cannot be deleted unless factory settings are restored. The following are my personal suggestions. If you use the mobile phone usage record in your mobile phone healthily, there is no big impact. Then don't delete it. After all, the content displayed in the mobile phone usage record is not fixed and will be refreshed every once in a while.
I hope my answer is helpful to you. Ask me if you don't understand.
