Quick Diagnosis Tips
Phone says storage full but you can't find large files: Open AnExplorer → navigate to root or internal storage → enable Sort by size to surface the largest files and folders.
Downloads not showing in Files app:
AnExplorer shows /sdcard/Download/ directly. Go to AnExplorer → Internal Storage → Download.
SD card not visible: Check if the SD card appears in the AnExplorer sidebar under Storage. If not, go to Android Settings → Storage → check if the card is mounted.
