We don't really need any confirmation that the Galaxy Note 4 will be coming out later this year, but there's a slight chance the company might launch its next flagship phablet a little earlier than planned. Samsung recently updated its SideSync software to work on all Windows computers, and in the hardware compatibility list, the company has mentioned the Galaxy Note 4 as one of the devices that SideSync now supports. Now, this doesn't exactly mean much and could be a result of someone typing in Galaxy Note 4 instead of Galaxy Note 3, though it makes us wonder if Samsung is making a habit of sneaking in upcoming product names in such lists just to build up anticipation, and also if the Note 4 might come to market earlier than its predecessors.
The Galaxy Note 4 is expected to arrive in the third quarter this year, supposedly with a new form factor that could include a curved (or even three-sided) display. Details on its specs are currently unknown, though it's possible it might be the first Samsung smartphone to sport a 2K display (2,560×1,440.)
