Today's smartphones have bigger and better screens than ever before. But, while a 4- or 5-inch screen may feel roomy on your mobile device, it's probably less than a quarter the size of to the screen that your laptop or desktop boasts. If you'd like to use all of those inches for viewing and controlling your Android phone, meet AirDroid, a handy mobile application that allows you to take complete control of your Android device via your computer's Web browser.

AirDroid is supposed to work on all major browsers, but I had difficulty when I tested it using Internet Explorer 9: my connection kept terminating abruptly. But when I switched my browser to Google Chrome or Mozilla Firefox, I had no problems at all.

Once the connection is established, you can use AirDroid's slick Web interface to navigate the contents of your phone. You can view photos and videos (a QuickTime plug-in is required), and transfer files between the computer and the phone. You also can view your collection of Android apps, installing and uninstalling titles as you'd like. Additional options include reading SMS messages, and sending new ones from your browser. You also can share clipboard text between your computer and phone; organize contacts; check and delete call logs; and upload and download ringtones.

AirDroid isn't perfect. It occasionally stumbled when I tried to view photos via my Web browser, telling me the requested content could not be loaded. I also noticed a delay when trying to send SMS messages from my browser; they arrived a few minutes after I pressed send. And AirDroid can't be used to make voice calls. But, let's face it, if it included that feature, I might never to go back to using that 4-inch phone screen again.

Note: The Download button takes you to the vendor's site, where you can use this Web-based software.
