Do illiterate people have mobile phones? I suggest that you can develop a mobile phone with photo function, and then you can store the photos of the corresponding people, not the names. ...

1, the function you mentioned is what Android phones do now. It uses a menu with icons and text display, which can be used as long as you remember the icons, and can meet the daily needs of illiterate people. In the storage part of contacts, you can set large photos and display them in the list management.

2. If you can't read, if you want to send short messages, the installed software can send voice (such as WeChat) and the current Apple mobile phone can realize voice search function.

Finally, no company is willing to develop a mobile phone for illiterate people because the market is too small. Mobile phone manufacturers will only load some convenient functions into ordinary mobile phones to realize the concept of liberating people. In other words, today's mobile phones can largely meet the needs of illiterate people.
