The Samsung Galaxy Note 4 is rumored to be released in September of this year with speculation focusing on a 4K display, but 64-bit processor support is postponed until next year.

Samsung has previously been consistent about its product release date and feature rumors with last year's Galaxy Note 3 release rumors almost entirely spot-on.

The Galaxy Note 3 was first announced at September 2013's annual IFA trade show in Berlin, Germany. The Samsung Unpacked event during the show announced the third generation of the popular Galaxy note, while the product itself released very shortly after on September 25 (October in the U.S. and Japan).

While not much is known about the Galaxy Note 4 itself, we do know that Samsung predictably reserves these Unpacked events for the really big launches. Last year's Unpacked event announcing the Note 3 was called "Episode 2" after an "Episode 1" announced the Galaxy S4 smartphone. Already this year has seen the Unpacked Episode 1 in February with the Galaxy S5's announcement, so it only makes sense that the Episode 2 event will follow last year's lead by announcing the Galaxy Note 4. This year's event will take place from September 5th through the 10th in Berlin.

As for the Galaxy Note 4's features, rumors indicate that the "phablet" will get much of the same technology as the Galaxy S5 smartphone, including dust resistance and water resistance "in up to one meter of water for up to 30 minutes."

Reports from Bloomberg indicate a three-sided display will be used for the Note 4, allowing messages on the screen to be read from an angle. CNET was reporting that Samsung is confident that its 64-bit processor chips will be ready sometime this year, but recent reports point out that next year is much more likely with Android's current lack of support for 64-bit chips.

Some feature rumors that also seem most likely for the Note 4 include handwriting recognition on the lockscreen and a 4K (3840 pixels x 2160 lines) resolution. The AMOLED Ultra HD smartphone display has been confirmed by Samsung for production, although it is unclear if it will be available in time for the Note 4.
