One UI 8.5 Leak Reveals Galaxy S26 Designs as Reports Point to Late‑January Launch

Firmware code featuring model codenames plus device illustrations strengthens expectations of a modest hardware refresh.

Overview

  • 2D renders and references in One UI 8.5 code effectively show the Galaxy S26, S26+ and S26 Ultra designs and list internal codenames M1, M2 and M3.
  • The phones are expected to debut One UI 8.5 on Android 16, with leaks indicating a beta for the Galaxy S25 series begins in December.
  • Multiple reports suggest a chipset split, with Snapdragon 8 Elite Gen 5 tipped for the Ultra and Exynos 2600 likely powering the S26 and S26+ in many regions.
  • Camera rumors point to evolutionary changes: the Ultra keeping a 200MP main sensor with a wider f/1.4 aperture and a new 3x telephoto, plus larger sensors on some lenses.
  • Battery and charging leaks indicate the Ultra retains a 5,000mAh pack as the base model rises to 4,300mAh, with possible charging bumps to about 60W wired and 25W wireless, while a late‑January reveal with mid‑February shipping is being floated.
