Viber's Sticker Market allows you to download free and paid graphics (stickers), which can then be used in chat conversations. Custom graphics (stickers) have become an increasingly popular feature in instant messaging apps, where they are generally seen as fun way of adding both a colourful and personal element to standard text-based chats.
The refinements to Viber's chat experience in the new version also include details like showing when your messages has been seen and whether your contact is online. With the new version Viber also becomes the first app that we are aware of to use a custom notification sound for incoming push notifications (a feature that was added in the GDR3 software update). It is now also possible, via the apps' settings, to hide notification content. Together with improved overall performance (loading speed and push notification deliver), the new features add additional polish to an already slick app.
This latest update continues Viber's policy of regular updates for its Windows Phone app, which has made Viber one of the best VoIP and messaging based apps available for Microsoft's mobile platform.
