The only issues I've ever had on Android are when there's more than one DJI Controller-aware app running at the same time. They tend to fight over the USB connection to the controller when you plug it in/power it up. I always kill DJI Go (if it's running) before launching Litchi and vice-versa. I'm not aware of any other Android apps that conflict with flight software besides other flight software. That's not to say that there isn't something out there, but I've yet to encounter it.
