> An early build of Samsung's Expert RAW app for the Galaxy S27 and One UI 9.5 adds two custom buttons by the shutter, Burst mode, a Tint control and a wider simulated aperture range, with signs of video coming later.

Samsung is reworking Expert RAW, its pro camera app, for the [Galaxy S27](https://idevice.com/phones/galaxy-s/roadmap) and One UI 9.5. An early build brings a new look, more ways to set it up and a few new shooting controls, according to SamMobile, which tried it.

The new layout shows up the moment the app opens. Manual controls get clearer labels and bigger adjustment panels. The quick controls menu grows into a grid several rows deep, and a lot of the menus now sit on see-through panels.

Modes are easier to reach, too. A selector at the top left opens a grid with Expert mode and the tools people already know: Virtual Aperture, Virtual Reflector, the ND filter and astrophotography. None of those are new. What changes is where you find them, and you can tell the app to reopen in whatever mode you used last.

Two buttons now sit beside the shutter, and you pick what they do. The options are camera settings, exposure lock, picture size, timer, aspect ratio, metering, the histogram, focus peaking and autofocus area as options. If you shoot in Expert RAW a lot, that's the change you'll feel most, since the controls you reach for every time stay under your thumb.

There's a padlock at the top right that locks your settings so a stray tap can't change them. Tap it again to unlock. The histogram gets bigger as well: tap the small graph and a larger panel opens with separate white, red, green and blue plots.

The new shooting features are Burst mode, a Tint control and a choice of photo aspect ratios. Virtual Aperture also gets a much wider range. On the [Galaxy S26 Ultra](https://idevice.com/phones/galaxy-s/roadmap/s26-ultra) it stops at f/16. In this build you can pick anything from f/1.4 to f/22.

That aperture is still software. Virtual Aperture fakes depth of field and background blur after the fact and the S27 series isn't expected to get a camera with a physical variable aperture.

The build also has settings for video stabilization and for resolution and frame rate. Expert RAW is a stills app today, so those hint that Samsung wants it to shoot video at some point. They're settings in an early build, though, not a feature you can use yet.

If you're weighing an S27, this is a software change and not new camera hardware. Samsung hasn't said anything about the new app yet.
