What is the reason why phonetic symbols can't type the corresponding words?

The reason why phonetic symbols can't type the corresponding words is that the mobile phone doesn't display the touch keyboard. The solution is as follows:

1. Check whether you are using your own input method. If not, try to switch the input method.

2. Turn off the phone and restart it.

3. Clear keyboard data: Open mobile phone settings-Application Manager-Chinese input method-Clear data.

4. If all the above methods fail, back up the data in the mobile phone first, and then restore the factory settings.
