The phrase refers to acquiring a specific version of a popular sandbox game for mobile devices via an APK file. This indicates a desire to install the application, build number 62 of the 1.21 update, on an Android device. The term implies either downloading from a third-party source or obtaining the installation file for manual installation.
This method of acquisition can be useful for users who need to install an older version, access the application when the official app store is unavailable, or bypass geographical restrictions. However, it carries potential security risks if the file is sourced from unverified origins. Previously, obtaining applications through APK files was more common before the widespread adoption of official app stores.
