No Bluetooth (BLE) Support
Air Actions are gone: You can no longer use gesture-based controls, remote shutter (taking photos), app navigation, slide transitions, or spelling/rewinding features via S Pen.
Samsung rationale: Usage data suggested very few users actually used these features; removing Bluetooth reduces complexity and weight.
No External Battery Required
The new S Pen is purely passive—with Bluetooth gone, there’s no need for an internal battery—which makes it lighter and more streamlined.
What Still Works (Same as S24 Ultra)
Core Stylus Functions
4,096 levels of pressure sensitivity, 0.7 mm tip, excellent responsiveness for drawing, sketching, and writing.
Air Command Menu & Productivity Tools
Tapping in with the S Pen (near the screen + button) still brings up the customizable Air Command hub—includes tools like Smart Select, Translate, Magnify, Screen-off Memo, quick notes, handwriting-to-text, note summaries, and more.
Safety Feature: S Pen Left Behind Warning
The phone still alerts you if you walk away without your S Pen—even without Bluetooth using EMF detection.
Galaxy AI Integration
The S Pen works seamlessly with AI features like Sketch-to-Image, Circle to Search, AI Note Assist, and more within One UI 7’s Galaxy AI ecosystem.

What Users Are Saying
> “Samsung removed the Bluetooth module and gyroscope sensors… losing Air Actions functionality.”
> “I’m deeply disappointed… I’d set my phone on a spot, use the S-Pen to snap photos remotely. Now that’s gone.”
Some users lament this change as a step backward—removing what made the S Pen uniquely capable in times like solo travel or presentations. Others note that alternative remotes exist (like Galaxy Watch or Ring).
Bottom Line
The Galaxy S25 Ultra S Pen retains everything that makes it a great stylus for creativity and productivity—but loses its remote control superpowers (Air Actions, shutter, app control). If those features were important to you, it may feel like a downgrade. However, for core writing, drawing, AI-enhanced workflows, and note-taking, the S Pen remains powerful—and now lighter.
