CES 2026 has seen the debut of Solver, an innovative accessory that adds two programmable haptic buttons to smartphones. This small, rectangular device magnetically attaches to the rear of both iPhone and Android devices, offering users a quick way to trigger actions without needing to unlock their phones. Each button's function is fully customizable by the user.

The capabilities of Solver's buttons are extensive. Users can program them to launch specific applications such as Notes, YouTube, or Spotify. More advanced customization allows for the creation of complex sequences of actions or shortcuts. For instance, a single tap could initiate emergency video recording, automatically send the footage via messages, and even share the user's location, initiate a 911 call, record audio, and sound an alarm.

Remarkably, Solver operates using Near Field Communication (NFC) technology, eliminating the need for batteries, charging, or Bluetooth connections. This makes it a seamless and always-ready addition for those who miss physical buttons or desire instant access to device functions. Solver is set to launch at CES with multiple color options, priced at $140.
