A slew of images pertaining to the flagship Samsung Galaxy S6 running the Android 6.0 Marshmallow update has been leaked.

It’s a well-known fact that Samsung is gearing up to release the Android 6.0 Marshmallow update for the Galaxy S6, Galaxy Note 5, Galaxy S6 Edge and Galaxy S6 Edge+, among others. Following the Note 5 leak, the freshly leaked images of the S6 shows a “flattened version of TouchWiz” UI, Tech Times reported. The pull-down status shutter, which is used to gain quick access to settings and notifications, has also been updated featuring a refined white background and blue text combination.

Samsung has also apparently introduced a “Pro” mode for the camera app. This mode is already part of the Samsung Galaxy Note 5 and it reportedly lets users to access new camera features like setting the shutter speed, exposure, white balance and ISO, along with other manual settings.

Speaking of rollout date, a leaked roadmap recently showed the time frame at which Samsung will be rolling out the Android 6.0 Marshmallow OS update. Based on the report, the power-packed phablet Galaxy Note 5 will receive the firmware pack sometime in December. When it comes to Galaxy S6 series of devices, the expected OTA date has been pegged as January 2016.

Like the S6, the leaked screenshots running the Android 6.0 Marshmallow update on the Galaxy Note 5 reportedly showed a similar flatter TouchWiz UI, which apparently comes very closer to the stock Android design seen in the Nexus devices. This means, the custom UI of Samsung has been fine tuned to emulate Google's Material Design language, introduced back when the search giant released Android 5.0 Lollipop OS. With the new version of TouchWiz UI, Samsung has seemingly ditched drop shadows, gradients and 3D effects.

Here are some of the screenshots sourced by Phone Arena via Weibo account:
