Galaxy S27 Ultra may not bring major S Pen reforms

It has been over 15 years since Samsung began shipping the S Pen stylus with Galaxy devices. Throughout this time, the S Pen has relied on the same Electromagnetic Resonance (EMR) technology. A few months ago, it was rumored that Samsung could switch to a newer S Pen technology with the Galaxy S27 Ultra, but that may not happen.

A report from ETNews claims that Samsung tested a new type of stylus for the Galaxy S27 Ultra but ultimately decided not to use it. EMR requires a digitizer to be embedded in the display. AES, another stylus technology, does not rely on a digitizer. Instead, it uses a stylus with a built-in battery and an internal power system, and it depends on the capacitive touchscreen to register input. However, this approach makes the stylus thicker.

Samsung reportedly developed a new stylus technology that combines the advantages of both AES and EMR, eliminating the need for a battery or a digitizer. However, the company has postponed adopting this technology, and the report does not explain the reason for the delay.

Since the Qi2 wireless charging standard requires neodymium magnets to be placed inside smartphones, which can interfere with the EMR-based S Pen, it is likely that Samsung will eventually move away from EMR. However, the company may be waiting for its new technology to mature before introducing it in future Galaxy S Ultra devices.
