These has been multiple conflicting rumours lately about the the Samsung Galaxy S7 lineup. Few days back, GSMArena also reported that there will be 3 devices in the S7 lineup by confirming from its contacts over ITSKINS, namely Samsung Galaxy S7, Galaxy S7 Edge and Galaxy S7+. But it looks like there is indeed a fourth device, presumably Samsung Galaxy S7 Edge Plus, in the works as suggested by this screenshot leaked earlier today.
According to the screenshot and information leaked by the redditor, the said device features a 5.7 inches Quad HD display, 12MP camera at the back, a 5MP front camera. All this is packed inside a full meta body design running on Snapdragon 820 coupled with 4GB of RAM while carrying an internal storage of 32GB. According to the leakster, it has a micro-usb port, not USB Type-C. Leakster also says that he forgot to check the sd card to confirm if it has any microSD slot or not.
Camera with a lower resolution suggests that the device might be having something different for that department. Few months back, PhoneArena also reported that Samsung trademarked BRITECELL indicating towards better performance in low-light conditions.
