We all like to think that once we lock our phones and set our pin numbers our privacy is guaranteed, that is not the case. To unlock anything you will need the pin number correct? not the case. Strangers should not be able to see any kind of data, or any kind of personal information you may have stored.
Sadly this is a fact of life, your personal info is not exactly 100% safe. There has been an issue going around effecting not only individuals but business owners as well. Folks have had their info tampered with. A CEO of a Toledo Tow Truck Company had his whole schedule and inventory info deleted away and a private catering company even reported they might have had some sensitive info deleted as well.
