According to Android Geeks, this information comes via the same inside source who accurately pegged the Note III’s launch date. The source goes on to mention that Samsung will “send out the invitations to the Unpacked event sometime mid-August.” It’s unclear if the “release date” mentioned means you’ll be able to walk into a store buy a Note 4 on September 4th, or if Samsung merely plans to hold its launch event possibly begin preorders on that day. As reported at the time, the Note III didn’t officially go on sale until September 25th of last year. As for what to expect, rumored specs published by GSMArena suggest that the new Note will have a 5.7-inch 1440 by 2560-pixel screen (for 515 pixels per inch) a 20.1-megapixel camera, have either Exynos Hexa or Snapdragon 801 chipset innards powering the device. GSMArena points to a ruggedized, waterproof design as a possibility as well.
