Samsung fans are eagerly looking forward to the Galaxy Note 5 and Galaxy S6 Edge Plus release, which is just a few hours away. And now, new details about the Galaxy S7 have popped up.

While it may appear a little out of the blue, Samsung's next flagship has been gaining momentum for quite some time. According to some leaked internal documents shared on Weibo, the Korean tech giant is tinkering with Qualcomm Snapdragon 820 chipset on Galaxy S7, Phone Arena reports.

The leaked documents appear to be Samsung's roadmap for Android M upgrade. The Samsung Galaxy S7 reference is made with its codename, Junfrau, with the Qualcomm MSM8996 version, which is the Snapdragon 820 chipset. Interestingly, there's also a mention of a new codename Hero with Galaxy S7 Jungrau, but there hasn't been any leaks in the past about the new reference, GforGames reports. So it is hard to speculate what the new keyword Hero means at the moment.

The leaked information on the Galaxy S7 chipset resonates earlier reports hinting at Samsung testing Galaxy S7 with both Qualcomm and Exynos processors.

In another report last week, Samsung switched from the aging Waterfall development process to much-improved "Agile." As a result, the Galaxy S7 development schedule will be shortened by a month or two. We might not see the new Galaxy S7 anytime this year, as some reports hinted in the past, but the handset's release will likely be expedited to sometime in January.

Other specifications of the Galaxy S7 remain a mystery. Samsung is yet to confirm the Galaxy S7 and considering there's a long time before the actual release, we might be treated to frequent rumours and leaks in the coming days. Right now, Samsung's sole focus is releasing the Galaxy Note 5 and Galaxy S6 Edge Plus. The long-teased Unpacked August 2015 event will commence at 11 am (EDT). In India, fans can live stream the event starting 8:30 pm from the company's official website.
