I want to clear most but not all the scores of email addresses and phone numbers on the contact section of an old Galaxy S4. Is there an easier way of doing this than on the phone itself? For example some sogtware I can use on my computer and then copy the edited file to the phone.
I'm not personally aware of any software but do be careful if you find some as the risk could be is that it bodges up your contacts.
Personally I would go through them one by one.
