With the launch of the Galaxy S6 edge+ and Galaxy Note 5 behind it, Samsung is now focusing on its flagship handset for next year: the Galaxy S7. Thanks to the folks over at SamMobile, we now have some details about the Korean company’s next flagship.

Samsung has codenamed the Galaxy S7 as ‘Project Lucky’ because 7 has long been considered a lucky number. The more interesting part, however, is that Samsung is testing the Galaxy S7 with its new Exynos 8890 chipset. This chipset will make use of Samsung’s Mongoose CPU architecture and will be the company’s first custom ARM cores. Unlike this year though, Samsung does plan on launching certain variants of the Galaxy S7 with a Snapdragon 820 chip inside, particularly in markets like the United States where CDMA networks are sill prevalent.

Additionally, the source says that Samsung is working on getting its UFS 2.0 NAND chips to play nice with external microSD cards. The main reason why Samsung did not include a microSD card slot on any of its flagship devices this year was that its blazing fast UFS 2.0 storage chips were not compatible with them. However, the company is trying to come up with a method to make the two different storage interfaces play nicely, though it it still unclear if the Galaxy S7 will come with a microSD card slot or not.

Lastly, the source says that Samsung is testing a new 20MP ISOCELL sensor that it plans on using on the Galaxy S7. It is also working on a project dubbed “all lens cover” but details about this project are unknown for now.
