In what is either a savvy marketing ploy or an accidental leak, Samsung's Indonesian branch seems to have confirmed that some level of waterproofing is back on the cards for the Samsung Galaxy S7 and S7 Edge.

The video above (which will no doubt delight those who have been on the soggy end of a water damaged S6) shows Indonesian archer Dellie Threesyadinda braving the rain in the middle of a picturesque forest before stopping to watch a video, unfazed by the water pouring on to the curved Edge display.

Waterproofing has been rumoured to be returning to Samsung's next flagship after its notable absence from the S6 range and this short promotional video taken from the Samsung Indonesia YouTube channel appears to confirm its reappearance.

Elsewhere in the video, we see appearances of the official Samsung wireless charging pad and a brief glimpse of the camera that, after a brief snippet showing off the flash on the back, could suggest improvements have been made on the S6 when it comes to low light performance.

A website that accompanies the promotional teaser further hints at low-light photography being at the forefront of the Samsung Galaxy S7 with the below image. This would tally with reports that the S7 will have a 12MP snapper designed to let in more light and create clear, vivid images, designed to be an advancement of the numerically superior 16MP camera found on the S6.

With Samsung's Unpacked event on 21 February set as the date the Korean company will officially show off the phone to the public, you might be left wondering what exactly it will have left to show after the numerous leaks in recent weeks.

In terms of the aesthetics of the phone, the teaser tallies with the already leaked photos of the handset that show how similar the design language is to that of the S6, or in the case of the above video the S6 Edge.

With the albeit confirmed return of expandable SD card storage and waterproofing, Samsung may well have rectified two of the most bemoaned omissions from its predecessor. But, with even the S7's expected battery capacity of 3,600mAh now being revealed in a document sent to the US Federal Communications Commission, does Samsung have any more tricks up its sleeve for the announcement a day before Mobile World Congress (MWC) 2016 opens its doors?

A healthy announcement?

With sport and fitness a key theme of the teaser, another leak from Samsung (at this point it is probably quite damp at its head office in Seoul) could give us an idea of the potential market for the S7 and S7 Edge. The device currently known as the SM-R150, or internally as the Triathlon, looks set to enhance Samsung's fitness and activity tracking repertoire and in the leaked teaser, Threesyadinda is seen clearly sporting a pink-strapped version of the Gear S2. Could these two be a match made in health heaven on the MWC 2016 stage?
