If somebody tries and fails to access your phone three times, Android phones running today's update to Lookout Mobile Security (download) will be able to take a photo of the culprit.

Two new features today bolster the app's already robust security options. The Lock Cam feature -- which Lookout said in a blog post announcing the changes will be rolled out over the next week to free users -- takes a photo using your phone's front-facing camera, records the location data based on your phone's GPS, and then sends the package to your e-mail account.

If you've paid for a premium Lookout subscription, you'll get the feature immediately. To activate it, go to the app's Settings and make sure both Advanced Protection and Lock Cam have been enabled. If you don't see the Lock Cam option, it hasn't been rolled out to you yet.

Unlike the Lock Cam, the new Lock Screen message feature is restricted to premium accounts only. The feature lets you leave a message double the length of a tweet, at 300 characters, which will appear on your lock screen.

The feature must be accessed from the Lookout management portal at Lookout.com, then clicking the Missing Device Tab and the Lock option. The lock screen message is currently limited to English-language installs of Lookout only. While Ice Cream Sandwich owners get the lock screen option by default, older versions of Android aren't able to customize the lock screen with a message.
