Mine went gray on Saturday, and then today it was black. I will see what version app I'm running and will try to go back to 1.39 what do I have to lose? WOOPS, I think you were talking about the Android app. I'm running the iOS app. All the P2V+ software is dated 4/7 including the iOS app which shows the latest is 37. I don't even know where to look to see which version I'm running, but I haven't changed the firmware it was delivered with, so I assume I'm running 37. I will play around with some of the tricks mentioned and see what happens.
Update: I think I've tried everything suggested, but I got nothing. Too bad, because it was working so well.....100% with no problems! then this! Sucks! OBTW, I found where to locate version number I'm running.....same as what's listed as latest. I've tried calling DJI, they don't answer and the cut the connection; sent them a support request, nothing; and tried an email.....at least they sent an auto reply saying they're looking at it. :-(
