Design Change: Unlike the flat-sided S25 Ultra S Pen, the S26 Ultra stylus is curved on one side to match the device's edge.
Insertion Note: It has a specific insertion direction; inserting it incorrectly causes it to protrude from the body.
Functionality: Offers 4,096 levels of pressure sensitivity, Bluetooth for air actions, low-latency writing, and IP68 water/dust resistance.
Performance Note: S Pen usage can be affected if a magnetic wireless charger is attached to the phone, causing input skipping.
Features: Supports AI-powered features including note-taking, text translation, and screen magnification.
