The Basic things this phone would need would be what a flip phone has to offer. Sometime people just want a basic phone, but a modern one this is the idea.
A Micro-Phone/ A Basic Card Sized Phone running Arduino Perhaps.
An OLED Display, keypad, a mirco sd for memory, processor, antenna, recharable battery.
I'm asking the community for anyone who may want to make something like this even if its salvage of a basic phone.
Thank you for your time.
