Hi, I have a phantom vision 2 Plus and use a Samsung Tab3 All with the latest firmware, software and App. Wifi expander pointed to the DJI Very many times I loose my wifi connection and don't have vision. Also when the DJI is not far away (50 to 100 meters) I can control the DJI without problems. What could be the problem?

It seems to be a general problem with DJI, they use poor electronic komponents, mine (PV2 vision) had also gone blind cause defect wifi board (just 2 year old)

I'm afraid that the issue is that your Samsung Tab 3 does not have enough processing power to run the latest version of the app.
