distance limit

I am using a Galaxy 8+ and running Litchi. No matter where I seem to fly I can at best only reach 3300 feet from the RC before my connectivity bar signal indicators drop off, then to red, and then nothing. Any thoughts on the matter?

Hello, I have been flying the mavic with no issues on firmware 1.03.0400 and on the GO 4 app v 4.0.2 on my android phone for a long time. Today I used the mavic with same firmware but using an iPad mini 4 with the latest GO 4 app. 2 issues! Message saying I am in a class D area and cannot fly...
