This popped into my head the other day following a conversation with an Android user who said they wished there was a way to lock their private data but still allow others to make calls and use the internet.
That's what this mode does.
Guest mode creates a temporary account on your smartphone that is free from any of your personal information. No photos. No contacts. No messages. No files.
It also disables the phone feature, but you can choose to activate that if you want.
So, how do you access this feature? Well, it normally lives at Settings > System > Advanced > Multiple Users, but not always. If you can't find it, a search for users should bring it up.
When you find it, you'll see it at the bottom of the list of Google accounts tied to the handset. To switch, tap on it, and the handset will switch over.
The process is fast and only takes a few seconds.
To switch back, navigate back to Multiple Users and tap Remove Guest.
If you want to give the Guest Mode access to the phone, before going into Guest, click on the cog next to it and enable Turn on phone calls.
Also, for quick access, you can make this feature available from the lock screen. Handy if you use it regularly.
It's a cool feature that helps keep your private stuff private.
