About this app

This app is an automatic file sync and backup tool. It lets you automatically synchronize files and folders with Microsoft OneDrive cloud storage and with your other devices. It is an ideal tool for photo sync, document and file backup, automatic file transfer, automatic file sharing between devices,...

New files in your cloud account are automatically downloaded onto your device. New files in your device are uploaded. If you delete a file on one side, it will be deleted on the other side. It works across multiple devices (your phone and your tablet). If their folders are synced with the same cloud account, they will be kept in sync with each other.

This is how OneDrive works on computers but not on Android. Two-way automatic synchronization should be an essential function of the official app. For whatever reason, it is not the case. OneSync is here to fill the gap.

All file transfers and communications between user devices and cloud storage servers are securely encrypted and do not go through our servers. No outsiders will be able to decrypt, see or modify any file contents.

It works well but sometimes stops working, and you have to crank the handle to get it going again. Make sure to turn on notifications for sync failures and disable notifications for successful syncs. (Note that on Samsung phones you must first go to Settings > Notifications > Advanced settings and turn on "Manage notification categories for each app".)

It's there in the app settings / Notifications. There choose which types of notications you want to receive or none at all.

No doubt this is a best tool, but I am currently using the “upload and then delete" sync method, but I’m facing an issue where the images are not getting deleted from my device after the specified number of days. I have tried changing the retention period to 7 days, 30 days, etc., but the images are still only being uploaded to the cloud and not removed from the device as expected. Could you please help me understand what might be causing this issue and how to fix it?

I can't explain how great this is and I'm very happy it. Native access to all my OneDrive photos and files are incredible unlike with the garbage way the actual OneDrive app does it. They have a Google Drive app too but too bad they didn't make a Google Photos one. There shouldn't be any surprise that the more often you sync, the more it drains your battery. This shouldn't be a reason to take off any stars, it's common sense and they even have a options to help with that.
