If you have a Huawei smartphone, you have placed a phone app on the Home screen that you can use to make calls.
Now it is possible that this very phone app has suddenly disappeared.
If this is the case with your Huawei smartphone, you can add it again. The reason for this is usually the following:
If you have activated "Drawer" as the start screen style, i.e. the Home screen and App menu are displayed separately, then it can happen that the phone app suddenly no longer exists on the start screen.
Usually you remove it by mistake and then notice it later. Sounds strange but so =).
Add phone app back to Drawer – Instructions
Therefore you have to switch from the Home screen to the App menu and scroll to the letter "T". Here you can see the phone app.
Press and hold it with your finger until it can be placed on the Home screen in the Drawer again.
Release the app to finally place it again.
You can then start the phone app from the Home screen on your Huawei smartphone as usual.
