Whats off-Turn Off WhatsApp

The app calls the Android App manager and shows the administration of WhatsApp. Here WhatsApp can be terminated directly. If you start WhatsApp again, the new messages are retrieved. Until then, you're in WhatsApp offline (only one hook, messages will not be delivered). However, one can continue to surf the Internet and use all other applications.

Advantage of the "app":
Rather than to go more step by the administration menus, you can finish WhatsApp directly.
Unfortunately, you can not quit WhatsApp directly (unless you have his phone rooted - but because invalidates the warranty). But so it works out pretty easily. Have Fun.

Thanks again to Sven for support.

Oh, because of the message that errors can occur: So far I have not found any WhatsApp error - otherwise please message.
