From Android 4.2, Airplane Mode can be toggled from the device system settings only so this app will no longer work.

This update just adds maxSdkVersion="16" (Android 4.1) to the global section of the manifest, so the Play Store will not allow 4.2 and higher system versions to install this app.

This is an Android team decision, not mine.
