I have purchased the Litchi app and the DJI Go app keeps shuting the litchi app down. I have a S6 can anyone advise as I need both apps? I already know you can only have one or the other app open at any one time but even if the Go app is shut it still shuts litchi- I have to keep deleting the DJI Go app entirely to use the other app.

Yes, don't run both at the same time. You need to do more than just close the GO app and run Litchi. You need to be sure GO is not running in the background. In short, what you have to do "I have to keep deleting the DJI Go app entirely to use the other app" is what we all have to do. There may be a way to get your tablets OS to ignore background apps, but failing that, that's the step you must take.

Edit: this is not a big problem. Yesterday, I was going back and forth between GO and LITCHI while the bird was up in the air and had no problems. Remember, the bird will fly / hover when there is no app running at all.
