Why can't Lenovo mobile phone s930 return to the home page by pressing the primary key?

Sorry for the inconvenience caused to your use!

If you click the four-leaf clover button in the middle of the bottom of the phone, you can't return to the home page, and the touch button is invalid. Here, we suggest that you try to solve it through the following situations and methods:

A. Intermittent appearance: it may be that the current equipment running resources are insufficient or the system files are abnormal, resulting in failure to respond to the operation in time. It is recommended that you optimize the system and close the background system programs regularly. If it cannot be improved, please back up the fuselage data and try to restore the factory settings.

B high frequency or no response at all: the touch buttons at the bottom of the screen belong to the touch screen. If it is high frequency or has completely failed, it is more likely to be caused by abnormal driving at the bottom of the system or the failure of the touch screen itself. Here, I suggest you send it to the maintenance point in time to ensure the normal use in the future.
