Google+ was launched on 28th June and till then it has gained lots of achievements from all over the world. The white interface of Google+ is good but I would love to use Google+ in black and many others also seek the same. To solve this problem, a developer from XDA forum, namely ecsnead69, has developed such an app which shows the entire Google+ in black instead of bright white.
To use this app, rooted device is not required, users are just requested to make sure to check installing apps from unknown source in the application settings. After doing that unzip the downloaded file and simply install the apk using a file manager.
Those users who have an AMOLED powered Smartphone, they will sure love the Google+ in black as the AMOLED makes the magic on maintaining the battery life of the Android device.
