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. No need to download files to a desktop first.
Key features:
- Cloud-based scanning (no downloads required)
- Algorithm 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 media directly via the Graph API.
Available on Google Play: https://play.google.com/store/apps/details?id=com.onedrive.mediaops&pcampaignid=web_share
Would love feedback from the community - especially if you've been dealing with the Samsung/OneDrive sync duplicate issue.

Nice problem choice—this is a very real pain point for OneDrive + Android users, especially Samsung owners. A few thoughts, split into questions to strengthen adoption.
Questions…
You don’t need to answer all of these here, but they’re worth addressing in your Play Store listing or FAQ:
1. Privacy & permissions
- Is anything sent to your servers?
2. Rate limits / large libraries
- How does it behave with 100k+ photos?
- Does Graph API throttling slow scans significantly?
3. False positives
- Can users adjust sensitivity?
4. Video duplicates
- Any limits on video duration/size?
5. OneDrive account types
- Personal vs Business accounts?
- Multiple accounts supported?
- Nice work 🙂— this is exactly the kind of “why doesn’t the platform do this?” app that gains loyal users.
