Notably, I encountered a few issues while removing and placing the phone: If you accidentally open up an application on the phone while placing it, for instance, that might break the pairing. A few times, Samsung reps had to outright reset the Note 4 and start from scratch because it froze. These are prototype devices and not the final product that'll ship to consumers later this year, but there's some roughness to how the phone is physically paired. A slight jingle plays when it connects, which is a nice touch, but I'd also like a more secure docking area. It feels like trying to jam a phone into a micro-USB port at an awkward angle, and that's not a great first experience.
