If you want to see your Facebook profile or page as someone else, then here are the steps to do this task on PC and Android:
Sign into Facebook and then go to your profile by clicking on the profile name at the top.
Click on "View as" option which you can see besides "Update Info."
Now, you can see the profile as it looks to others and a notification at the top stating that you're currently viewing the profile as "Public."
If you want to view how your profile looks to a specific person (in other words, your particular friend), then click on "View as Specific Person."
Begin typing your friend name, and you can see suggestions. Choose your friend name, and you can see how your profile looks to that specific friend.
If you want to get back to your view, click on the "X" in the notification at the top. Alternatively, you can click on your profile name at the top to do this task.
That's all. You can see the profile as "Public" now.
Tap on "Exit View" option if you wish to get back to your view.
Go to the Facebook page you wish and then click on three horizontal dots beside the "Share."
Now, you can see "View as Page Visitor" option. Click on it.
That's all. Now, you can see the page as it looks to the visitor.
Click on the "Switch back to your view" link in the notification at the top to get back to your view. Alternatively, you can click on the page name on the left side of the screen to do this task.
Now, you can see the page in the view of the visitor.
If you want to get back to your view, then click "X" at the top.
