At this point in time not much is known about the phone, but the latest rumor from SamMobile has revealed that Samsung has apparently begun development of the firmware for the Galaxy S7. According to their sources, the development actually begun a month earlier than when Samsung developed the firmware for the Galaxy S6.
What does this mean? If you recall, there were rumors that suggested that the Galaxy S7 could be unveiled in February 2016 (there have also been rumors suggesting January) so we guess it’s not surprising that work has already begun, and it could also serve to corroborate the claims that it could be launched earlier than expected.
So far what we know about the phone is that it might come in 3 variants. It could also be powered by a Qualcomm Snapdragon 820 and Samsung’s Exynos chipset, depending on the market the phone is released in. Either way it’s best taken with a grain of salt for now, but hopefully more details will surface soon.
