Just to update, I have been playing around more with the Robin, so far everything is working as expected...except the camera. I have noticed the delay between pressing the shutter and the phone actually taking the photo has varied between 1-3 seconds. This seems dependent on the amount of light when the photos are taken. (less light, longer delay)
Also, if you switch to manual camera mode and change the ISO to 100-200, the photos are much quicker. Although this doesn't work for all lighting scenarios so my feeling is this is just a software issue. I am pretty sure Nextbit is working on it from what I've read on their forums. Otherwise the camera typically takes a good photo.
For me it's somewhat of an issue, I tried to take photos of my always on the move 2yr old and by the time the shutter went off, he was completely out of frame. I hope the fix is coming soon and significantly improves this otherwise I probably won't be using the Robin much.
