It's just been a couple of weeks since Samsung first rolled out the Galaxy S7 and S7 edge Nougat beta firmware, and looks like an update to the firmware is already on the way. This was confirmed by the tech giant during a conversation with a beta tester. As one would expect, the new/updated firmware will contain fixes for most (if not all) of the bugs that have been reported by beta testers so far. Sadly, there's currently no information on exactly when the firmware will graduate to public release and the roll-out will begin, although we expect it to happen sooner than later. Via
