What's the best Android app to quickly free up storage space on my phone?

AI Cleaner is a straightforward tool designed to tackle one of the most common Android frustrations: dwindling storage space. For anyone whose phone constantly nags about being full, this app automates the cleanup process. It scans the device's storage for junk files left behind by apps, unnecessary cache data, duplicate photos, and residual files from uninstalled applications. The interface is simple, presenting results in a clear, categorized list where users can review what will be deleted before confirming. A one-tap 'Clean' option is available for those who prefer a hands-off approach. This is particularly useful after uninstalling large apps or when managing a photo library that has accumulated many similar shots. While the core functionality is effective, some users might find the advanced file management features less comprehensive than dedicated file explorer apps. Reviews indicate the process is notably fast, which aligns with feedback stating it 'saves more time.' The app does not include a backup feature, so caution is advised when selecting system cache for deletion. Overall, for routine maintenance to clear several gigabytes of clutter, AI Cleaner provides a focused and user-friendly solution.
