From Lollipop you can create different user accounts e.g. if you want to keep social and professional separate, or if others use your device. You can, therefore, manage your different identities / accounts with WhatsApp / Facebook / Twitter on the same device.
- Set up a new user – go to Settings> Users> Add user.
- Access the profile from the shortcuts by tapping on the user icon and choosing the profile you prefer.
- In each of the profiles you will have separate personal files, e.g. photos and accounts of services such as Gmail, WhatsApp, Facebook, or Twitter.
- … and there you go!
