Commentary: A universal AI and better battery life might be previews of what's being announced later this year.

The Galaxy S25 is a tale of two AIs: Gemini and Bixby. Yes, while Google's Gemini AI assistant sits at the forefront—it can finally be triggered through a long press of the power button—Samsung is bringing its original Bixby voice assistant out from the shadows.

Samsung touted improvements to its Galaxy AI system and the AI-enabled Google Gemini assistant. Most of the upgrades are available on the latest One UI 7 software release, which will be available for older S-series generations sometime after the S25 release, Samsung says.
