In the P2VP series, if you left your gimbal clamp on and forgot to remove to transfer files, the gimbal would heat up and a fat warning would appear on your smart device. Unfortunately, when you are transferring files you don't need to have your smart device and you wont see the warning that you have left the gimbal clamp on. How cool is it in the P3 series. DJI has made the camera go limp when the USB cable is plugged into the PC. This means you can leave the clamp in when transferring files/upgrade firmware etc.
