I have a new Zenphone 3 too, and I'm also loving it.
I've also just got an Osmo gimble for it, to take rock solid video.
The biggest problem I've had so far is - I haven't had enough time off work to play with my new toys!
But I'm on holiday next week, so a good chance to check out all the features on the camera and see what it can do. So far, like you, I am really impressed with it.
