Built an Android app for OneDrive duplicate detection (something I wish Microsoft offered natively)

After years of dealing with duplicate photos and videos in OneDrive, I built a solution and wanted to share it with the community.

**The problem:**
- Samsung Gallery sync creates duplicates in both "Camera Roll" and "Samsung Gallery" folders
- WhatsApp media gets backed up twice (original + shared copy)
- App resets/reinstalls trigger re-uploads with "(1)" suffixes
- No native duplicate detection in OneDrive

**What I built:**
OneDrive MediaOps - an Android app that scans for duplicates directly in the cloud using perceptual image hashing. No need to download files to a desktop first.

Key features:
- Cloud-based scanning (no downloads required)
- Perceptual hashing catches visually identical photos even with different filenames
- Preview before deleting
- Batch deletion

**Why cloud-based matters:**
With 50GB+ of photos, downloading everything to run a desktop duplicate finder wasn't practical. This scans thumbnails directly via the Graph API.

Would love feedback from the community - especially if you've been dealing with the Samsung/OneDrive sync duplicate issue.
