First Samsung Galaxy Note 5 rumors hint at crazy 2K or 4K screen

Now that Samsung's Galaxy S6 is out of the gate, the Internet's attention is gravitating towards Samsung's bigger flagship: the Galaxy Note 5. Samsung typically busts out the new Note in September at IFA, but the very first rumors about the phablet are already out, and we expect to see a whole lot more of them ahead of its launch.
Here's what we know so far.

Same jumbo screen with 2K or 4K clarity

Samsung's screens are known for being very bright, colorful, and bold. The Galaxy S6 upped the ante with a super high resolution of 2,560 x 1,440 pixels, which is typically referred to as a 2K screen. SamMobile suggests that the Galaxy Note 5 may also have a 2K resolution, but Samsung could also bump the screen up to 4K.

If Samsung gives the Note 5 a 4K screen, it would be one of the very first smartphones with that kind of resolution. Of course, the higher the resolution, the more energy the screen will suck from the battery, which is something that typically upsets users. The screen will be Super AMOLED, as usual, and is likely to be the same size as the Note 4's 5.7-inch screen.
Samsung is also expected to reboot the Galaxy Note Edge when it introduces the Note 5. The curved screen is rumored to measure 5.4 or 5.5-inches, and sport two edges. It's unclear whether the edges will be substantial and useable like they were on the first variant, or if they'll be pretty, but useless, like those on the Galaxy S6 Edge.

The processor may be Exynos, Snapdragon, or both

Samsung is currently testing a variety of processors, SamMobile's source says, so it's unclear which chip the company will decide to use in the end. Reports peg Qualcomm's Snapdragon 808 as the chip that may power the Note Edge 2, but there are two Samsung Exynos processors in consideration, too.
TheExynos 7422 may power the Note 5, and if it does, it will offer an all-in-one solution (ePoP), which combines the CPU, GPU, RAM, storage, and modem on one chip. Another alternative is the Exynos 7430, but it sounds as though that processor isn't ready for use in a mainstream device just yet.

Camera possibilities and more

The Note 5's camera and other specs remain in shadow, but the Edge 2 may have a 16-megapixel back camera with OIS and an 8-megapixel front-facing camera. Of course, these are early spec reports, so it's possible that the cameras will be entirely different. Another weird spec possibility is offering a Note Edge 2 model with just 16GB of internal storage, which seems unlikely to be true.
