Phantom 3 Advanced Firmware 1.6 Samsung Galaxy S6 Edge Plus Marshmallow OS DJI Go v2.7.2 Litchi v3.3.0 First, I turn on my P3A then I connect my phone to my controller then turn on my controller. I will get a pop up asking me if I want to connect to DJI Go or Litchi. I launch which one I prefer and it connects to my Phantom. The next time I go to use it I need to go into settings/applications/default applications and uncheck whichever app I chose to open previously, then I go through the process listed above and it connects without issue. Now, when my phone is connected and I turn on my controller nothing happens. If I manually open either app neither will connect to phantom. I went through the default apps and nothing was checked. I had this issue recently but when I rebooted my hone it worked fine, now it wont. When use my Samsung TabS2 it works perfectly. As always, any help is very appreciated!
