If you don’t want your Facebook profile to be explored by anyone, you must know how to lock profile Facebook. 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.
