YOU CAN NOW OPEN TWO WHATSAPP OR USE MULTIPLE SOCIAL ACCOUNTS IN YOUR ANDROID DEVICE.

Parrarel Space app enables you do that. 
Parallel Space is an application that allows you to manage two different user accounts for any app installed on your Android device. Basically, you can create two different accounts for anything like Facebook, Instagram, Clash of the Clans, Candy Crush Saga, etc.
Parallel Space is much simpler than you might expect. Basically, it's an application that creates a virtual space that is completely independent and separate on your device that allows you to run other apps inside. That way, you can use the same application twice on the same device. One runs on your device, and the other runs on Parallel Space.
Another great feature about Parallel Space is how little memory it actually takes up on your device, just over 2MB. Not only that, but this application doesn't require root privileges so it will work on any Android device. However, Parallel Space requests a huge number of permissions because it needs them for each app used on it.
Parallel Space is an extremely interesting app. Thanks to Parallel Space you can use a number of accounts for any app on your device at the same time. This feature can be specially useful for social networking and gaming.
