I’ve been doing my own testing on my device (Samsung Galaxy s5) to push the limits of the app with my device and see what causes it to freeze so I know what it can handle to make my flight experience more memorable. Aside from doing everything that the mods have posted, I also tried something else after hearing a few other complaints.
I recall reading about how imagery is rendered to your device a few months back, so I tried something. If I fly in cockpit view the whole flight, I have ZERO problems. The imagery in the direction I’m facing is rendered without issues. Once you change your camera view and look a different direction, more imagery is being rendered, which puts more stress on the app and the device. My device tends to freeze up if I switch camera angles frequently throughout my flight as I don’t believe my device can handle the load.
I’m not saying stay in cockpit for the whole flight, that would ruin the global experience. However, staying mindful of how much you switch views may be be the difference between an app crash and a successful flight!
