Your four-point checklist
The marks stay only in this open page. They are reminders, not a compatibility test, a device scan or a safety certification.
Check the release, then the phone
Android version requirements belong to a particular release. Find your Android version in the phone’s About settings and compare it with the publisher’s stated requirement for the exact file. Avoid treating the game name as a universal device specification.
The app manifest can declare a minimum platform requirement. Hardware, available storage and publisher support may also matter. A supported Android version alone does not prove that every app feature will work.
Leave room for the process
A downloaded APK occupies storage, and installation can need additional working space and installed data. Review the phone’s storage view rather than adding an invented fixed multiplier to the file size. Remove only items you understand and have backed up where needed.
