The Galaxy S25 has a new “suggested replies” feature that uses on-device AI to suggest replies to messages you receive.

The new Samsung Galaxy S25 series is now available worldwide. This lineup includes the Galaxy S25, Galaxy S25 Plus, and Galaxy S25 Ultra, all featuring an array of advanced AI capabilities. Many of these features were highlighted during Samsung’s latest Galaxy Unpacked event, where the company announced the new phones. Many were not, however.

Samsung’s Galaxy S-series is in its software era. Maybe the whole smartphone industry is, too, save for a few phones with hinges (Samsung’s included). But overall, we have exited the hardware-driven innovation cycle and are firmly in the midst of a software-based one.

Like the rest of the Samsung Galaxy S25 lineup, the Samsung Galaxy S25 Ultra introduces AI features to improve how we communicate. Combining the best Samsung phone on the market right now with AI writing assist features means your messages are enhanced, along with real-time translation, style changes, and smart suggestions.

As regular as clockwork, Samsung has launched its 2025 flagship phones trio, fronted by the Galaxy S25 Ultra. Beneath the big boss is this model on review, the Galaxy S25 Plus, acting as the middleman above the smaller-scale base S25 model.

All this to say the Galaxy S25 ($800), Galaxy S25+ ($1,000), and Galaxy S25 Ultra ($1,300) are powerful, reliable, and well-equipped smartphones. They're excellent upgrades if you're coming from a three or four-year-old device. They're just not otherwise interesting or exciting.

The Galaxy S25 Plus is a tougher sell given how it shares the same set of Galaxy AI features and cameras found on the cheaper S25 model. It's a powerful, big-screen phone, but it's hampered by a dimmer display and modest battery life improvements over its predecessor.

To fold or not to fold, that is the question? We've got the answer with this head-to-head comparison of the Samsung Galaxy S25 Ultra and the Samsung Galaxy Z Fold 6.

When you trade in your old phone with T-Mobile, you'll get it for free. New and existing customers can swap an old device in any condition for a new Galaxy S25+ for free, or use the credit for up to $1,000 off other models like the top-of-the-line Samsung Galaxy S25 Ultra (delivered as 24 monthly credits on your bill).

The Galaxy S25 series have a ton of Galaxy AI-powered features, and a new feature for Samsung Keyboard is now being added.
