There are currently only a few hundred Android apps designed specifically for tablets running Google Android 3.0 or higher. But there are hundreds of thousands of apps for Android smartphones and most of them actually look halfway decent on tablets with higher resolution screens. Some don’t though.
Soon Google is going to offer users a tool to force those apps to fill your tablet display. Basically you’ll see a button on the bottom of your screen whenever you’re running an app that isn’t designed for Honeycomb tablets. It will allow you to either “stretch” or “zoom” to fill the screen. Stretch mode is the default, but if that doesn’t work, the new zoom option will run the app in an emulated mode and scale it up to fit the screen.
Apps will look a little more pixelated when you use this mode, but it sure beats running them in a tiny window on your 10 inch tablet.
