After four years of no problems my Galaxy tab S2 has suddenly stopped syncing with my email provider. I deleted the cache and the data but that didn't solve the problem. I then deleted the account and tried to add it as a new account but I get this message: "Can't set up account. A security connection error has occurred."
[I usually use the tablet every day but hadn't used it for a week and the battery had gone flat.]
Any solutions?
