Samsung's Indonesian arm appears to have shown off the Galaxy S7 almost a week earlier than planned. An unlisted commercial marked #TheNextGalaxy and posted to the branch's official YouTube channel shows Indonesian archer Dellie Threesyadinda training while using the new phone, a tech website reported.

In the video, Threesyadinda is seen operating a smartphone which has a similar design to last year's Galaxy S6 and S6 Edge, in a downpour suggesting a return to waterproofing. The phone is also seen being used with a wireless charging pad.

The smartphones are rumoured to have metal and glass design but may come at the sacrifice of power user features. They might come in a true 'black' colour option this year apart from silver, white, and gold. The Galaxy S7 Edge may come with a larger 5.5-inch display (the regular S7 will remain at 5.1 inches).

Both the S7 and S7 Edge will likely retain the resolution of 1440 x 2560 as their predecessors with Super AMOLED displays. Samsung is likely to again offer 32GB and 64GB options for internal storage and may launch a 128GB version.

Media reported in January that the S7 will include a 3,000mAh battery, up from the S6's 2550mAh and S7 Edge may have a 3,600mAh battery. It is also rumoured that phones might see a 'downgrade' in camera resolution but offer f/1.7 aperture to perform even better in low light settings. The smartphones may come with new Snapdragon 820 in the US market, sticking with its own silicon – Samsung's Exynos processors – elsewhere.
