Samsung ChatOn fans who have been missing the app on their tablets will be happy to know that Samsung has optimized the instant messenger for Android tablets. ChatOn is comparable to BBM and iMessage, and while it may not be as popular it is a pretty decent app if you now a lot of people with Samsung phones. If you’re a ChatOn user and you have a Honeycomb or an Ice Cream Sandwich tablet, find the update in the Google Play Store.
