Nobody is perfect and Android neither.
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!

* Explorer: A full-fledged file manager.
* Searcher: Helps you find files by name or content.
