I am still running 1.4 because everything has worked flawlessly until today. I havent flown in a few months due to winter, so I charged a battery today but I get zero video in the app. App version is 2.7.1 on my S6 and tablet is 2.5.1 and both did the same thing. I restarted a few times with the same results. All controls seem to work and pics and videos did save to sd. Wondering if this is common at all, but I may have to finally update the firmware.
