What should I do if the dial key and SMS key on my Huawei mobile phone are missing?

Hello, this situation is mainly due to the increasing number of software and junk files during the use of mobile phones, resulting in abnormal functions of software and systems.

Fault analysis and suggestions:

1, software, garbage, affecting the normal function of software.

Clear the cache garbage and restart the phone.

2. The program is unstable.

Open a program, select a program, select a dialer, and then select Clear Data.

3. The system is unstable.

It is suggested that after using the mobile phone for a period of time, back up the address book and materials and restore the factory settings.

4. Poor compatibility and stability of software.

If this kind of fault occurs repeatedly after processing, it is the design problem of the software itself.

Consider using third-party software.
