CES 2026 Solver Programmable Buttons: The Battery-Free Tactile Revolution

You don't need to charge it, and you don't need Bluetooth. At CES 2026, a startup is proving that the best way to interact with your high-tech smartphone might be a simple physical click. Solver, a tiny rectangular add-on, officially debuted at the CES Unveiled event, bringing two programmable haptic buttons to the back of your mobile device.

Why the CES 2026 Solver Programmable Buttons Are Magic

The magic behind Solver lies in what it lacks: a battery. Unlike almost every other tech gadget shown during the event, Solver works without any internal power source or wires. It uses Near Field Communication (NFC) technology to communicate with your phone. This means it's always ready to go, and you'll never have to worry about your buttons dying when you need them most.

From Spotify to SOS: Unlimited Customization

Each of the 2 buttons on Solver is fully programmable. While you can use them to quickly open Notes or YouTube, the real power is in complex shortcuts. During the live demo, the team showcased a single-tap emergency sequence: the device automatically started recording video, shared the user's location, called 911, and sounded a loud alarm simultaneously. It's an impressive use of hardware to bypass the friction of unlocking a screen.
