Ever since its debut late last year, Samsung's ChatON application has been a moderate hit amongst folks using iOS, BlackBerry, Windows Phone and Android devices. Now, along with outing a slightly redesigned logo (pictured above), the Korean outfit's also updated its app in Google's sweet OS to version 1.9.5 on handsets, or 1.7.3 if you're handling one of those larger slabs. Most notably, the ChatON refresh brings the London 2012 spirit with a timely "Olympic Buddy" feature, which keeps you in the loop by pushing out breaking news, daily schedules and, of course, medal tables. Additionally, there's now a walkie-talkie service within the phone application, while the tablet variant gained the ability to send documents to your friends -- not to mention it finally lets you use fancy emoticons. Feeling pretty antsy to give it a try? That Google Play link below will take you there.
