The Android Market is an inextricable component of every Android device. That is one of the important areas that Google prioritizes and focuses on. Being so, Google has again improved the famous Android Market with the unofficial release of Android Market version 3.1.3 that leaked out online.

The updated app has several new exciting things to offer since the last version. The app has the same app icons and interface from Android Market version 3.0.26. But, this latest leaked version reveals that Google has integrated the +1 button on every listed app. Other significant changes are PIN security for purchasing apps, new settings menu, and faster and smoother browsing.

+1 Button

In the newest version of the Android Market, a +1 button appears on every app listed on the Market. The +1 button’s sole purpose is to let people know what they think about an app (i.e., whether they like it or not). Clicking the +1 button for an app is tantamount to a recommendation or a vote in favor of the app. This practically makes app discovery and selection easier, since the number of +1s for an app can often indicate the app’s popularity. The +1 button could help you determine which app is fab and which is not.

PIN Security

The previous version of the Android Market allows the phone’s owner–or anyone else who gets a hold of the phone–to download, install, and purchase apps. The Android Market’s latest update will make such transactions more secure with PIN code verification. Before the phone can purchase and install an app from the Android Market, a PIN code will now be asked before the transaction can proceed. This is a nifty security feature that can protect your phone from unwanted downloads. The PIN code feature can be enabled or disabled in the User Control screen.

Easier Browsing

Android Market 3.1.3 also added some features for smoother and faster browsing. The app now allows a categorized view of apps. It can also filter apps into books, movies, and music, so you don’t have to browse through hundreds of applications before you find the app that interests you. You may also filter your content and look only for apps with a certain popularity level.

These are a few of the features on the new Android Market 3.1.3. If you want to try it out before Google officially pushes it out to users, grab and install the APK from the mirror links below. You may need to enable “Unknown Sources” from the Settings > Applications screen. The leaked APK hasn’t been confirmed to work on Honeycomb tablets yet, but feel free to try. Root access is not required.
