I tapped the .msf file, and it imported into MobileSheets without an error. So that is not what I experienced. It may depend on the Android OS version and the launcher that is being used on the device. If you are seeing that on your Samsung S7 FE device, then I don't have an explanation, as I tested on my Samsung S8 Ultra which should be very similar to the S7 FE, although the S8 Ultra has Android 15 instead of Android 12.
