Thanks mate, I don't want to do that as it's only a few months old. I think I will send it to DJI for getting it fixed. Thanks for your help though. Appreciate it.
Haven't found a similar problem on any forum so far - may be it's a one off.
I recently bought the Phantom 4 Pro, the shutter button on the remote doesn't take a picture. I clearly hear the sound of it taking a picture when pressed but nothing is written on to the SD Card 9 out of 10 times. I have to use the button on the ipad to take a picture.
