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.

The new Galaxy S25 line was officially launched at Samsung Galaxy Unpacked today. However, it took Samsung a long time to get to the main event. Unlike previous events where the latest smartphones kicked things off, it took 30 minutes for Samsung to start talking about the S25 and a whole hour to eventually even show off the S25 line.
