Google has updated its official Gmail application for Android with a new filter that's designed to protect you from external phishing attacks by warning you when you click on a link that could point to a malicious website.

Even though the filter can't warn you about the fake Google Docs invitations circulating (since they're pointing back to Google's own website), it's still a pretty neat tool to have.

"Not all affected email will necessarily be dangerous, [but] we encourage you to be extra careful about clicking on links in messages that you're not sure about. And with this update, you'll have another tool to make these kinds of decisions," says the firm.

The upgrade is making the rounds in stages

According to the release notes, the server-side upgrade is making the rounds in stages and could take a maximum of ten days to reach all users — so if it hasn't reached your device yet, don't panic. It will shortly.
