Gr.Bell / mobile phone

This is v-button project for the old.
It’s difficult for the old to use a mobile phone.
Most of mobile phones have multi-functions.
This frustrates the old.
Also, figure-buttons confuse the old.
Because the old gradually decrease ability to read figures and letters.

Therefore, The old need a figure-less & letter-less‘s mobile phone.
The old need only a Visual image-Button’s mobile phone.
