I have a Dji Phantom 3 Advanced and a Tablet Samsung Tab E with 8GB memory.
The GO App frequently stops the FPV image and reports NO SIGNAL on top center.
If I return to main screen of the app and activate Image again it usualy recovers.
Can anybody say Why? Could it be lack of memory in the tablet?
How much memory should It have? Can a SD card improve it?
