FYI. I noticed an update for DJI GO 4 dated 23 Feb 2017. I installed it. All my previous problems with my Samsung S7 Edge (Android 7) and the DJI GO 4 disappeared! I was using Litchi because the previous version of DJI GO and DJI GO 4 crashed every time on my phone! I almost bought an iPad Mini 2 or similar small tablet to fly. Glad I waited. They activated Live Streaming on Facebook too. Haven't tried it yet. Fingers crossed DJO GO 4 keeps working.
Update: Flying on 25 Feb with my third battery and my phone's screen started to lag badly. Menus would not close and then it just locked up. Controller still functioned with the Mavic in a hover. I rebooted my phone, clear the local cache and reconnected. All was normal again.
