If you still need the APK file (e.g., you switched to a custom ROM or want it on a different Android 12 device):

If you own a Vivo smartphone running Android 12 (such as those with Funtouch OS 12 or OriginOS), the built-in Vivo File Manager is your go-to tool for cleaning junk files, managing documents, and organizing storage. However, many users search for “Vivo File Manager Android 12 download” because the app is either missing, accidentally uninstalled, or they want the latest version on a non-Vivo device.

Use a trusted APK repository like APKMirror (owned by the same team as Android Police). Search for “com.vivo.filemanager” – the official package name.
