Shortly after Samsung unveiled its current flagship smartphone, the Galaxy S6 and its Edge counterpart, rumors about its successor have already started to emerge.

Based on these rumors, the South Korean tech firm's upcoming device, dubbed as the Galaxy S7, is expected to sport upgraded specs.

Of course, since it will be the company's next flagship device, it's safe to assume that the Galaxy S7 will come with a bigger display. But aside from the size difference, some sources suggest that the device's screen might feature a totally different design, according to Value Walk.

Taking off from Samsung's previous patent filings, the company could adopt a game-changing move and debut the Galaxy S7 as a foldable smartphone. This means the device will come with a flexible screen. If Samsung pulls this off, it could become a pioneer in the foldable flagship handset sector.

For its processor, Phandroid reported that the future device will feature different chipset models depending on where it will be released. As suggested, Europe, Korea and Japan might receive a Galaxy S7 model powered by Samsung's own Exynos 8890 processor.

Other regions, such as China and the U.S., could see the next flagship handset running on the Snapdragon 820 processor from Qualcomm.

Regarding the Galaxy S7's camera settings, there are no confirmed details yet regarding the configurations. But, the device's main camera is expected to sport a 16-megapixel CMOS image sensor.

In terms of battery life, it would be best for Samsung to learn from its past mistakes and equip the Galaxy S7 with a bigger battery life. After the release of the Galaxy S6, a lot of users were disappointed after seeing the 2,550 mAh battery of the smartphone.

Fortunately, rumors are suggesting that the company's research and development department is working on a lithium-ion battery that can last up to five days. Hopefully, this technology will be able to make the cut as one of the final features of the Galaxy S7.

As for when the public can expect to see the new device, Samsung has been recently known for unveiling its devices at dates earlier than expected. Since the Galaxy S5, the company has chosen the Mobile World Congress as the main stage for the introduction of its flagship smartphones.

Following this trend, the company could unveil the Galaxy S7 during the same event next year, which is expected to happen in February. If this happens, then Samsung could officially release the handset by March, 2016.
