Looks like the S-Pen is losing the air gestures and Bluetooth capabilities that allow it to act as a remote camera shutter on the latest Samsung Galaxy S25 Ultra. I suspect it is due to the requirement of magnets in the new Qi2 wireless charging feature that’s being added.
The earlier editions of the Ultra series used to have stylus detection issues with magnet based accessories (like this reddit post notes), like cases which gave it MagSafe like capabilities. In fact I encountered this issue with my S23 when I tried a MagSafe equipped case with the S-Pen not working properly around the middle of the screen where the magnet is positioned on the back.
Not much to be done I suppose as the new model trades off the advanced stylus capabilities in favour of faster charging.
