You can use the Samsung Galaxy S8 to store your data directly in the Samsung Cloud. For this you have 15 GB available. This is a useful thing. However, the setting of the S8 is configured to sync photos from the gallery.
If you do not want to, then we now show you how to delete already synchronized photos in the Samsung Cloud. Just proceed as follows:
Start from the Home screen and then open:
App Menu --> Settings --> Cloud and Accounts
Here you can find "Samsung Cloud". Select the entry and you can see a small overview, which you can synchronize everything. Now tap "Manage Cloud Storage".
Here you will find "the gallery data". Tap the entry and then select "Delete". You must now authorize and the data is then deleted from the cloud of Samsung. Finished.
