SD Maid System Cleaning tool (Android) regains precious memory and keeps it clean and tidy. This app is intended for rooted devices. Without root functionality is limited. Apps you have already deleted sometimes leave data behind. The system constantly creates logs, crash reports, and debugs files you don't really need.
Version 0.9.7 has fixed missing entry to show/hide optimize dbs tab, updated German and English help file, updated Russian translations and help file, changed explorer refresh to catch loop on erratic granting of root permissions, and fixed a bug on some ROMs causing SD Maid to falsely detect root.
