The Hangouts app can be found on the Apps screen on your Samsung Galaxy tablet. If you don’t see it directly in the list of apps, look for it inside the Google folder. And if you still can’t find it, you can obtain the app from the Google Play Store. It’s free!
Hangouts hooks into your Google account. If you have any previous conversations, they’re listed on left side the main screen. The right side of the screen shows frequent contacts. If you scroll down the right side, you’ll see all your Google contacts.
The Hangouts app listens for incoming conversation requests; you can also start your own. You can even do other things on the tablet — you’ll be alerted via notification of an impending Hangout request.
To sign out of the app, which means you won’t receive any notifications, touch the Menu button and choose the Settings command. Choose the Sign Out item. (Scroll down to find that item.) Touch OK to confirm.
When using the tablet in the vertical orientation, you need to swipe the right side of the screen to see previous conversations or the contacts list.
Conversations are archived in the Hangouts app. To peruse a previous text chat, select it from the list on the left. Video calls aren’t archived, but you can review when the call took place and with whom.
To remove a previous conversation, long-press it. Touch the Trash icon that appears atop the screen.
Your friends can be on a computer or a mobile device to use Hangouts; it doesn’t matter which. But they must have a camera available to enable video chat.
