How to display the calendar on Huawei mobile phone is not allowed.

Hello, you can enter the "Settings" interface, click "Date and Time" and clear the "Automatically determine time and date" check box, and then you can set the time and date manually. Some operators' networks are completely synchronized (such as China Telecom), and manual date and time modification is not supported. It is recommended to update to the latest version at this time. If you have any questions or needs later, you can call Huawei's technical support hotline at 400-830-8300 or contact Bian Xiao to help you deal with these problems. At the same time, thank you for your support and attention to Huawei. Wish you a happy life!
