Prediction: The Galaxy Note 4 will have 4GB of RAM
Just like any other Galaxy Note device, the Note 4 will be huge, both in size and specs. Rumors say it might have a curved 2K display, 13 megapixel camera with OIS, and now recently, a 64-bit processor. Obviously these aren't official; they're just speculation.
As I was predicting the Galaxy Note 4 specs myself, I noticed something interesting. I'm not sure if this was intentional from Samsung, but consider this pattern:
Note 1: 1GB RAM
Note 2: 2GB RAM
Note 3: 3GB RAM
Note 4: 4GB RAM?
If Samsung followed this pattern, this would be sweet. Think about it, 4GB of RAM would be freakin' amazing, especially on a handheld device. While this might sound overkill, the combination of 4GB RAM, the rumored 64-bit processor, and Android L's 64-bit support, the speed would be great... as long as Samsung doesn't make TouchWiz even more bloated.
Once again, all of this is not true, but it's something to think about.
