FIELD AND BACKGROUND OF THE INVENTION

The invention relates to the field of smart terminals, and particularly relates to a bottom control method, a storage medium, and a smart terminal.

At present, smart terminals such as mobile phones and tablet computers basically have multiple physical keys, such as the “home” key, the switch key, the volume key, etc. which will destroy the structural integrity of the mobile phone and the manufacturing process of the smart terminals is cumbersome, and users often need to perform a large range of hand movements when using these keys, which leads to inconvenience for users when using smart terminals. In addition, too many physical keys are set which causes too many gaps. This makes it easy for dust to enter the smart terminal from the gaps between the physical keys and affects service life of the smart terminal.

Therefore, the existing technology needs to be improved and developed.
