Hi! I currently have a SGS4 but am ready for something new. I used to have an N4 and really enjoyed it, but that camera really stunk and I depend on having a good camera in my cell. So I'm getting to decide between the N6P, N5X, or SGS7. I'm having trouble with the idea of no SD card slot. Anyway, I've read about the specs. But are there any things about the phone that may help me decide that you'd only know after having and using it? Thanks in advance!
