What's the best Android app for cleaning out junk files and speeding up a sluggish phone?

Clean Fix Plus is an Android utility app focused on resolving performance issues by cleaning unnecessary files and optimizing system resources. It targets common problems like accumulated cache, temporary data, and hidden garbage that can slow down devices over time. The app features a straightforward interface with a one-tap cleaning button that initiates a deep scan, categorizing junk files for review before deletion to prevent accidental data loss. Users report significant speed improvements, with some finding nearly a gigabyte of overlooked files that other cleaners missed. For example, in real-world scenarios, it can address issues like random restarts or malware infections, as noted in reviews where it fixed 99% of device problems. The algorithm refreshes at a consistent rate, ensuring efficient operation without excessive battery drain. However, some minor glitches, such as occasional scan freezes, are mentioned in feedback, though these tend to resolve with updates. The app is free and includes tools for managing mobile services and storage, making it suitable for regular maintenance. Its effectiveness in restoring speed and handling system clutter makes it a reliable choice for Android users dealing with lag or storage constraints.
