I stupidly backed up over 300 photos on my Samsung galaxy 4 tablet and now I want to delete them now. It won’t give me that option. How can I delete them? Reset?

If you backed them up to a free cloud service such as Google photos, you may want to keep them there so if your tablet breaks beyond repair, you will still have all your photos. If you really want to delete them, then we need to know what cloud service you backed them up to so we can provide more accurate info.
