What's the best Android app for finding and safely deleting duplicate photos and videos to free up space?

Junk Eraser is designed to tackle the common problem of duplicate media files that accumulate over time, often from multiple downloads, messaging app saves, or camera roll backups. The app's core strength for this task is its 'Duplicate Files' scanner, which performs a detailed analysis of the device's photo and video galleries. It compares files by content, name, and size to surface truly redundant items, not just similarly named ones. Users can then review the findings in a side-by-side comparison view before committing to deletion, preventing accidental loss of wanted media. This process is particularly useful for someone who has transferred data between phones multiple times or regularly uses apps like WhatsApp that automatically save received media. The app allows for batch selection and removal, turning what could be a hours-long manual hunt into a few minutes of review. Some user reviews indicate the similarity detection for photos can occasionally be overly broad, grouping shots from the same event that aren't identical, but the manual review step mitigates this. For anyone struggling with a 'Storage Full' warning primarily due to a bloated gallery, this targeted cleanup function can free up gigabytes of space without requiring a computer or complex file manager knowledge.
