Software is far more interesting, with Google's Pixel UI on Android 17 taking a radically different approach compared to Samsung's One UI. As for the S26 Ultra, Samsung's standout software features in One UI 8.5 are more focused on customization. (Though One UI 9 launched on new Galaxy foldables in August, the update has not yet made its way out of beta on the S26 Ultra quite yet.) The most useful AI features on the S26 Ultra (aside from those housed in Google Gemini) include an improved Audio Eraser, which does feel a bit like black magic. The S26 Ultra now has Storage Sense, which lets you remotely browse file systems on other Galaxy phones, tablets and laptops.
