This maintenance suite is quite full-featured. The tools it includes focus on tasks ranging from eliminating duplicated files (in the paid Pro version) to exploring temporary files or searching for 'cadavers' that are no longer being used.
SD Maid has these characteristics, which are included in any other maintenance app. However, it stands out due to its 'AppControl' section that allows you to freeze, restart, and delete any program that you have installed on your phone, or even the programs that come by default if you have rooted your phone.
This utility will also optimize your phone's database and compress it to make it faster to access and to free up space. In addition, it will find the files that weigh too much so you can decide if you want to get rid of them.
As if that weren't enough, if you activate the paid Pro version, you can use the duplicated file deletion utility and an app cleaner.
