A security app often gives you functions beyond alerts that flag infections from malicious apps. Most mobile security suites offer ways to back up your phone—a feature sorely missing from Android—and some security tools can help you locate, lock, and wipe your device remotely should it be pilfered from your pocket. Installing a security suite on your phone may not sound like a glamorous task, but once you have set it up, you can rest easy knowing that you have a system in place in case anything goes wrong.
Lock your phone
This might seem obvious, but putting a PIN or pattern lock on your phone is one of the easiest ways to secure your device. Doing so keeps nosy friends out of your text messages and makes it harder for thieves to wipe and resell your phone. You can set a lock screen on your phone by going into Settings and making your way to the Security & Screen Lock option. Note that attackers and snoops can crack pattern locks by examining the streaks that you leave on the screen by entering your pattern over and over again, so a PIN is the way to go if you're worried about someone using your oily skin against you.
You lose the convenience of just being able to turn on your phone and get right into using it, but the increased protection is worth the extra hassle.
Look past the FUD
The most important thing to remember about Android security is that you shouldn't buy into all the scaremongering that media outlets report on an almost daily basis. Android's open nature makes it less secure than iOS or Windows Phone, but you can avoid most of the threats to your phone if you take even just one of the precautions described above. So while a plague of phone-bricking Trojan horses might be spreading via a shady app store in Ukraine, you and your freshly secured phone have nothing to worry about.
