If you have a Samsung device (Galaxy S4, S5, Note 3, 4...) you might receive the Android 5.0 (Lollipop) update soon.
We have received reports of crashes in Infinite Flight after users have installed the update on their devices. We strongly advise against updating to this new version of Android until we push an update that fixes this issue.
We apologize for the inconvenience and are working hard to find a solution as soon as possible.
