Optimize your Viber

Viber's settings are light years ahead of certain other instant messaging apps, allowing a degree of customization you can only dream of elsewhere. Use the settings menu to personalize your Viber experience, from showing message previews to new message popups, or setting automatic screen unlock for new message and illumination settings. There's even a built in chat history email service and you can set up Viber to send automatic free replies to SMSes whenever possible. You can also manage your message ''Seen'' and contact ''Last Online'' settings from within the app, set auto-download rules for pictures and video and organize your Wi-Fi ''sleep'' settings. Plus set your notifications to be aggregated rather than individual. How good is that!
