Okay so this is going to be a very newbie question but hear me out, so I bought a new P3A on eBay running firmware 1.3.20 with the RC running 1.5.80 and the app 2.8.2 on a galaxy S6. So when I go to the DJI GO app there is no option to select 2.7k video, I'm guessing this is because the 2.7k update came out with 1.4.0010 firmware. So in order to get 2.7k video I would have to update the firmware, right? Can someone advised which firmware to update to. Also what else will need to get updated to work with the new firmware. Thank you.
