Google has today announced that they are bringing Video Chat to Google Talk messaging service. Available over 3G/4G or WiFi you can video chat with your friends on Google Talk on other Android phones or the PC client.
In your Google Talk friends list, a video or voice chat button will appear next to your contacts and you can simply touch the button to connect with them. Any text chats from the person you’re talking with will be overlaid on your phone’s screen so you can read them without having to leave the video. And, if you need to check something else, the video pauses automatically so you can go back to your phone’s home screen or another app. The audio will keep going even though the video has paused.
This update requires Google 2.3 or greater, which means for now it will be limited to Google devices until carriers get their acts together.
