I am not able to set it as well as the channel for HD in DJI GO. I have tried it with Galaxy S5 and TAB S 8" and it is the same. If I connect the Tab or S5 to RC then switch it on and then P4 - I am not able to set anything in the HD option, There is nothing to set. But if I run DJI GO switch to P4, HD without connection to the RC and then I connect to RC I am able to set thw quality an the channel. Do you have the same experince?
