The description of Contacts Sync - Play With New Friends
Contacts Sync is an app that lets you automatically link all your phone's contacts to their WhatsApp profile pictures. This way, you will be able to see a contact's WhatsApp photo either from your contact list or whenever they call you. There are two prerequisites that you must fulfill to be able to use Contacts Sync correctly. The first: have WhatsApp installed on your device, otherwise the app won't be able to access the photos. And second: make sure your device is rooted. Without root permissions, the app won't be able to access the WhatsApp photos or automatically sync them to your contact list. Contacts Sync is a very interesting app, thanks to which you can quickly and easily customize your contact list. As long as you have fulfilled the two previously-mentioned requirements, the whole process will take less than a minute.
