Samsung Unpacked S25: Galaxy S25 phone available for preorder
Samsung announced the release of its next flagship phone, the Galaxy S25, at the Samsung Galaxy Unpacked S25 presentation on January 22. As is essential for any tech presentation in 2025, Generative AI was at the forefront of the event.
“We’re making it (AI) a reality right here right now,” said Roh, Samsung’s president and head of Mobile Experience™. “To make change possible, we built an AI OS from the ground up.”
Samsung Galaxy S25 offers business as usual outside of AI

The Samsung Galaxy S25 comes in three standard variants:
- The base model Samsung Galaxy S25 has a 6.2 inch display and up to 256 GB storage.
- Samsung Galaxy S25 Plus has a 6.7 inch display and up to 512 GB storage.
- The Samsung Galaxy S25 Ultra has a 6.9-inch display and up to 1TB of storage.
All three variants include the Snapdragon 8 Elite for the Galaxy chip and Google Gemini as its AI assistant. The largest model, the Ultra, weighs just 218 grams.
The Samsung Galaxy S25 can be preordered now, with the phones hitting store shelves on February 7th. Samsung offers Gemini Advanced and 2TB of cloud storage with purchase. The S25 retails at:
- $799.99 for the base model.
- $999.99 for Samsung Galaxy S25 Plus.
- $1,299.99 for the Samsung Galaxy S25 Ultra.
Samsung says the S25 offers the longest battery life ever from a Samsung phone – up to 31 hours of video.

Google extends to all aspects of the Gemini S25
Since the rest of the specs aren’t much different from the S24, Samsung wants AI – and especially its partnership with Google – to provide a reason to upgrade. After introducing the S24 with Google Gemini last year, Samsung has integrated AI even deeper into the S25. A dedicated side button will activate Google Gemini. It replaces most of the requests a user might have previously made to Samsung’s own Bixby digital assistant.
Gemini is multimodal, capable of responding to voice commands, answering questions about live video or identifying the music being played. It can transcribe and summarize calls during a call.
WATCH: OpenAI and Microsoft join forces on an AI infrastructure initiative that promises $500 billion over four years to power data centers and more.
The AI will have access to any app on the phone and can get information from all of them. The AI-curated “Now Brief” on the home screen will aggregate information like weather, upcoming meetings and sports scores from Google every morning. An “Evening Brief” summarizes the day at night.
As is expected from generative AI these days, Gemini on Samsung will be able to generate text, summarize text, edit images, and answer questions about pictures.
AI data lives on device
“As AI becomes more powerful, it must also become more personal to provide class-leading personalization, we are introducing the Personal Data Engine,” Roh said. “Now you can enjoy customized experiences while keeping your personal information safe on your device, not in the cloud.”
Essentially, the personal data engine means AI data from individual phones is not used for model training or advertising, Samsung said. Some AI queries may be removed after the interaction is complete.
To protect copyright and disclose when AI created an image, Samsung has adopted C2PA cryptography.
One UI 7 emerges from beta
Under the hood of the S25 is One UI 7 OS. Roh said Samsung is leveraging the operating system to reimagine Android “while keeping AI at the core.” One UI 7, beginning in general availability with the S25 series, enables:
- Extended writing tools including call transcripts.
- “Now Bar”, which includes timely notifications on the lock screen.
- Redesigned camera UX.
Developers and partners will have access to the new UI soon, Roh said.
AI is the new normal on smartphones
The Samsung Galaxy S25 series competes primarily with:
A slimmer version of the S25 is coming
At the end of the Unpacked presentation, Samsung released a teaser of the upcoming ultra-slim variant Galaxy S25 Edge. Release date or details have not been announced yet.
