Disconnects - normal or time for return?

[mobalized]

I've had my Mavic for 2 weeks, and I've flown about 7 hours with it. I have experienced approximately 5-10 disconnects where the app has indicated disconnected and I've had a hard time getting it to reconnect on my Note 4. Of those times, probably 3-4 have also had a controller disconnect. None of these were more than 200 yards line of sight. I've had other flights much further out through obstacles without disconnecting. I know other people have had similar instances, but is this just "normal" behavior, or should I be trying to exchange it with Amazon?

Thanks for feedback!
