. Nobody is perfect and neither is Android.
. Apps you have already removed leave something behind.
. Logs, crash reports and other files you don't really want are constantly being created.
. Your storage is collecting files and directories you don't recognize.
. Let.s not go on here... Let SD Maid help you!
SD Maid allows you to:
. Browse your whole device and manipulate files through a full-fledged file explorer.
. Remove superfluous files from your system.
. Manage installed user and system apps.
. Detect files formerly belonging to uninstalled apps.
. Search for files by name, content or date.
. Obtain a detailed overview of your devices storage.
. Optimize databases.
. Do actual app cleaning and remove expendable files, which supersedes what others may call 'cache cleaning'.
. Detect duplicate pictures, music or documents, independent of name or location.
. Run tools automatically on a schedule or via widgets.
Requirements: Android 5.0+
