Download OneSync APK for Android - All versions
Sometimes a new app version doesn't work well on older devices. The new app may not be compatible with your device's operating system. Until the developer fixes the issue, try using an older version that you know worked before. To find previous versions of OneSync, check its version history on the website Captain Droid. It has all available old file versions of the app available to download. Any OneSync version downloaded from Captain Droid will be completely virus-free and free.
