I can now confirm that wearing a smart watch creates interference with the mavic's remote. I just picked up my Samsung gear s3 and wore it while flying the mavic for the first time today. Since booting up the remote, I got a message saying strong remote interference. I have flown from my house about a dozen times without ever seeing this message. I took off anyway to test it out... I know... Im dumb. No toilet bowl, BUT, while pushing the stick full forward, it would go, but at a slight angle to the left. Before anything crazy happened, I hit the return to home. Mavic landed about 20 feet off from original take off spot. Booted everything down... took off the watch... booted all back up and the message was gone and the Mavic flew flawlessly. Hope this helps you!
