As a necessary step in moving forward with development, we will be increasing our minimum device requirements for Android in 21.1. Infinite Flight will now require a device with a 64bit processor and Android 7.0 or newer. This shouldn’t affect many of our users since most devices released in the last 4 years likely have a 64bit processor and Android 7.0 support. This decision does not come lightly but is necessary as we continue to add more features and maintain a good experience for as many users as possible.
If your device doesn’t have a 64bit processor and cannot be upgraded to Android 7.0, you will still be able to enjoy Infinite Flight on versions prior to 21.1.
To find out what processor your Android device has, please follow the instructions found in this article.
EDIT: Thank you to users who pointed out the above article references an app that is no longer available. Please try this app instead to help find out if your device is 32 or 64bit.
