This app only runs on Android 5.0 or higher (except Android 11). Please confirm you are running
Android 5.0 or higher (but not Android 11).
Unfortunately, the PSO2es Tweaker only works for Android 5.0 or higher and doesn't work with Android 11. Please use the manual installation instructions.
Instructions provided are for manual installation where one is either unable to use the PSO2es Tweaker (such as an incompatible Android device),
or prefer to manually patch out of preference. Please note that most buttons in the game cannot be translated as they're hardcoded into the game itself.
