As we grow older, the mobile phones we use are also updated. Different mobile phones may be suitable for different age groups. And this custom-made module mobile phone can be said to be very user-friendly. It has four module interfaces, sound, sensor, vision, and location, allowing users to customize their phones according to their own needs and preferences. In addition, users can add many additional modules to make the mobile phone more powerful. The smooth black touch screen allows users to check these functions in different ways and have a friendly operating environment. I believe that the mobile phone in the future should be designed like this. A mobile phone is not fixed and unchangeable, whether it is shape or function, and the operation interface is more personalized, which can be freely customized by users at will.
