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.

PREORDER BONUS ALERT: As of Jan. 22, shoppers who preorder an unlocked Samsung Galaxy S25 series smartphone from Amazon or Best Buy (starting at $799.99) will receive a free gift card worth $50 to $200, depending on the model.
