The Rotary Un-Smartphone
The Rotary Un-Smartphone is an open-source, kit-based mobile phone designed by Justine Haupt that emphasizes simplicity and functionality over smart features. It supports LTE and falls back to 3G, offering reliable voice and text capabilities without the complexity of a smartphone OS. The device includes a replaceable battery, physical controls, and privacy-focused features like a microphone cut-off switch.
