The caveat is this is build is still early in the development process, and some things can change between now and its expected rollout later this month or in July.
The biggest changes are coming to the Galaxy S6’ camera app, which gains support for shooting pictures in RAW mode, as well as lower ISO values, and a more intuitive way to adjust the manually exposure when taking a picture. The latter feature is demonstrated in the video above; basically, going through exposure brackets is as simple as swiping a slider.
The Galaxy S6 will also gain support for guest users, according to an older report from SamMobile.
The video goes through some of the more subtle changes coming to the Galaxy S6’ user interface, which include a toggle for disabling the S Finder and Quick Connect buttons from the Quick Settings interface, a more visible shortcut to the Themes Store in the Themes menu, and an option to give the wallpaper a parallax effect.
Google launched Android 5.1 on March 9, bringing bug fixes and a handful of new features, including Device Protection, which keeps the device locked even when the phone is reset, support for HD voice, and better quick settings tiles.
