Learning how to use any new device, or troubleshooting an issue on your smartphone can be a frustrating experience. Sure, you can call or text the tech expert in your family and ask for help for the umpteenth time, or if you own a Samsung Galaxy S7 or S7 Edge, you can video chat with Samsung support directly from your device.
Using the Samsung+ app, not only will you be able to see and hear the support representative, but he or she will -- with your permission -- be able to take control of your device and illustrate how to change your lock screen wallpaper or add an email account to your device.
To get started, download and install the Samsung+ app on your device.
Next, open the Samsung+ app and tap on the "+" sign in the lower-right corner. Next, tap on Video Chat from the list of options. Tap on Start Chat to begin the call. As noted in the dialogue, you will not be visible to the person you're chatting with unless you intentionally turn on your camera during the call.
In order for the person to walk you through troubleshooting an issue or completing a task, you'll need to grant permission for Samsung Assist to access your device.
When Samsung Assist is running, the words "Samsung Assist Active" will remain displayed in red on the bottom of your screen (see below).
In a test call, I asked for help changing my wallpaper. As you can see above, he was able to show me exactly where to go should I want to change the wallpaper again in the future, complete with circling the exact button I need to press.
