Today, I was doing a medium haul flight when the interface suddenly disappeared. The volume also disappeared. The flight was still progressing well without any lag or freezing spikes but I could not access the interface when I tapped the screen. A few internet connection mishaps occurred during the flight.
I reinstalled Infinite flight after previous scenarios and I always Restart my device before any flight. No other app other than IF was running.

This might be your problem Ive noticed that on older devices the new update glitches out some times causing this, and as your device is around 5 years old it is no surprise.
Does this happen with all flights or was it every now and then?
I have experienced it as well on Android where I would be flying and not able to bring it back. I usually had to hit the back button to get to the pause screen in order to get it working again. I don’t think I have experienced lately though.
