1. Under the Standby page, click "Application".

2. Click "Set".

3. Slide up the screen and click "Application Manager".

4. Slide the screen to the left and select "All".

5. Slide up the screen and click on "Samsung Cloud Date Relay".

6. Click "Clear Data".

7. Screen appears "All data for this application will be permanently deleted." Include all files, settings, accounts, databases, etc. ", click" OK ".

Once you've done this, you'll be able to synchronize your data with the Samsung account.
