How to protect yourself from the Stagefright security flaw

Stagefright is very likely the worst vulnerability to hit the Android ecosystem. All someone needs is your phone number in order to send a malicious MMS message that compromises your device. Even worse, the attacker can erase the message so you never know you’ve been hit.

The first thing you should do to protect yourself is turn off MMS auto-retrieval. The example below is from Google’s Messenger app, which is one of the best apps for text messaging.

Go to Advanced > Auto-retrieve and flip it off. The only downside is you’ll get prompted to accept or reject MMS messages, which are those that include images, video, or group texts. It’s a worthy inconvenience to prevent your device from becoming a spy phone that monitors your every move.
