I have a few questions I hope someone can answer;
1.  In DJI GO 4: I have a Samsung S8+ for my controller.  I keep getting  the memory 94% Full icon in the upper right corner of the screen.  All  the other normal icons scattered around the screen edge are gone except  the map.  Please advise what memory this "full icon" is refering to and  how do I correct the problem.
2.  I'm thinking about purchasing a Samsung Tab S3 so I can run DJI GO 4  and GS Pro and/or Litchi.  I've seen some negative feedback about the  S2.  Anyone with any positive feedback on this device?  Please advise.
