One of the controversial decisions Samsung made with the Galaxy S25 Ultra was eliminating Bluetooth support for the S Pen, which turns out to directly impact a Samsung DeX feature. With a Bluetooth enabled S Pen, like the one in last year’s Galaxy S24 Ultra, users could remotely snap photos with their S Pen by pressing its button.

Samsung's new flagship smartphone line predictably puts AI at the forefront of its experience. They're all up for pre-order now.

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.
