It's a quad core, not octa. Not that you'd need that much anyway. 16gb isn't great though if you like Apps. I know all about it as my S5 only has 16GB and I'm constantly out of room (as apps don't install on SD). Depends a bit on the footprint of preinstalled (cr)apps too (a whopping 4 GB with Samsung), let's hope they don't include too much junk. That said, I read that Android M will finally allow usage of the SD properly again, so if that phone will get an update it'll have plenty of room. That battery though, very good (on paper at least).
