In Blue Archive (and many Nexon-developed mobile games), error 80103 is a client-side storage check that triggers when your device reports less than the required free space for the game's update process. Unlike some games that only check for the final APK size, Blue Archive performs a double-check:
If your free space is less than patch size × 1.8, you get 80103.
