If you don’t want your Facebook profile to be explored by anyone, you must know . Once locked, no one can completely explore your Facebook profile until he/she is in your friend list. Here’s how you can do this:
1. On your Android device, login to your Facebook account.
2. Tap on the three-dot menu icon located next to “Add to Story”.
3. Select the “Lock Profile” option to lock your Facebook profile.
4. You can see a notification stating, “You Locked Your Profile”. Now on, whoever visits your Facebook account, other than people on your friend list, will not be able to see your complete Facebook profile.
