Fixes Android 16 QPR1+ storage permission bugs on AOSP-based ROMs. The Problem On AOSP-based ROMs built on Android 16 QPR1+, the system fails to properly create or set permissions on scoped storage directories during app installation: /storage/emulated/0/Android/data/<package>/ /storage/emulated/0/Android/obb/<package>/ /storage/emulated/0/Android/media/<package>/ This causes apps like PUBG, Telegram, WhatsApp, and many others to fail with storage access errors such as: "read/write permission error" "Unable to create directory" "You don't have applications that can handle the file type" Root Cause Android 16 QPR1+ uses f2fs bind-mounts for Android/data and Android/obb directories instead of routing them through FUSE. This causes two issues: Storage Directory Bug vold (Volume Daemon) fails to create app directories with correct permissions due to missing SELinux policies or broken FUSE passthrough patches. FileProvider Bug FileProvider.getUriForFile() internally calls File.getCanonicalPath(), which resolves the f2fs bind-mount to the lower filesystem path: /data/media/0/... instead of the expected FUSE path: /storage/emulated/0/... This causes a silent IllegalArgumentException, preventing apps from sharing files via content:// URIs. How It Works StorageFixer is a hybrid solution — a root Android app combined with an LSPosed/Xposed module.
