Wipe Your Lost Galaxy S 4 Clean
As a last ditch security option if your phone has been lost, you can wipe your Galaxy S 4 clean by using Mobile Management Software (MMS). MMS software can remotely disable your device or wipe it clean. Here are some of the possible scenarios:
You were robbed, and a thief has your phone.
Remote Lock: This app allows you to create a four-digit pin after your phone has been taken that, when sent to your phone from another cellular phone or a web page, locks down your phone. This is above and beyond the protection you get from your Screen Lock, and prevents further access to applications, phone, and data.
If you know that your phone was stolen — that is, not just lost — do not try to track down the thief yourself. Get the police involved and let them know that you have this service on your phone — and that you know where your phone is.
You are a very important executive or international spy. You stored important plans on your phone, and you have reason to believe that the other side has stolen your phone to acquire your secrets.
Remote Erase: Also known as Remote Wipe, this option resets the phone to its factory settings, wiping out all the information and settings on your phone.
You can’t add Remote Erase after you’ve lost your phone. You must sign up for this kind of service beforehand. It's not possible to remotely download the application to your phone. You need to have your phone in hand when you download and install either a lock or wipe app.
Each of the preceding kinds of applications is available from the Play Store. The simplest security applications are free, but the better quality apps, like the ones mentioned in the antivirus section, are about $10 and require a monthly service fee in the range of up to $5 monthly. Decide what options work for you, consider the price, and protect yourself.
