The most interesting AI is yet to come. The Galaxy S25 Plus will include Samsung's Personal Data Engine, a secure hardware partition that will gather information about you for the AI to digest. It will read your messages, listen to your calls, see your photos, and mind your calendar.

If you pre-order before that date directly from Samsung, however, you can pay for the 256GB model and pick up the 512GB for free. Or go one step beyond and buy the 512GB and receive a 1TB handset. It's a nice promo – and there'll be trade-in cash benefit too if you want to further the appeal.

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.
