I did a bit more troubleshooting and found that when I stream the file to my iPhone or iPad the speed is often not displayed which is good (I still find a few files here and there with the speed visible though but they are rare). However once I download the file to my device then the speed is displayed even with that video stamp option turned off. Due to that, maybe it's the App that has the issue and not the actual camera as the App version was also updated around the same time as the camera firmware. Doesn't really solve the problem though. Any Andriod users here having the same issue? Previously I was using a mini 0805 and you could turn the GPS off completely so there was no speed or maps or anything. Shame you can't do that with the RC500S as all I want is the video. I don't need a map, I know where I went. I'll wait until I hear back from DOD and will post their reply in case others are having the same problem.
