Huawei mobile phone calendar is missing?

Because this is a software. Some mobile phones can be uninstalled.

Have you got a license for your Huawei mobile phone? You can uninstall this calendar if you get permission.

If you don't get it, it's gone. Is it hidden?

Why don't you go back to the factory at any time?

If the factory settings are not restored. But it doesn't make sense.

Damn it, you are not that kind of software. You can download the next one online.

It's not just additional work. If you need it, you can go to the next one on the Internet.

Don't care too much about this software.
