So here are four tips to aid in keeping you safe.

You will find this in Settings and About Device then select Software Update
Make sure you update under wifi only - this will save you data
Updates are sent down to PROTECT you , don't ignore them.
Keep your Apps updated
Go to the Google Play Store icon on your device , look for the " hamburger menu " select " My Apps "and press Update
