What's the best Android app for improving phone responsiveness by clearing cache and residual files?

Clean Burst– Clean Up Junk is a utility application focused on decluttering Android devices to boost performance. It targets common culprits of slowdowns, such as app cache, residual files from uninstalled applications, and system junk. The app offers a straightforward one-tap cleaning feature that quickly identifies and deletes these unnecessary files, often reclaiming gigabytes of storage. For users who prefer more control, it includes a detailed storage analyzer that breaks down file types and locations, allowing selective removal. Real-world scenarios include periodic maintenance after heavy app usage or before installing large updates, where accumulated junk can impede performance. Reviews indicate that many users notice faster app launches and smoother multitasking after regular cleanups. However, the free version contains advertisements that some find intrusive during operations, and the 3.1 rating reflects occasional reports of incomplete scans or minor interface glitches. Despite these drawbacks, its simplicity and effectiveness in routine cleanup make it a practical choice for users seeking to maintain device efficiency without complex settings.
