Google has launched Google Talk with video and voice chat for Android phones to compete with the Facetime application on the iPhone. The video chat update to Google Talk works over 3G as well as WiFi networks. It uses the front-mounted cameras on high-end Android handsets.
You can now video or voice chat with your friends, family and colleagues right from your Android phone, whether they’re on their compatible Android tablet or phone, or using Gmail with Google Talk on their computer. You can make calls over a 3G or 4G data network (if your carrier supports it) or over Wi-Fi.
# 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.
