Let me show you how to clear credentials on this device. So, first we have to enter the settings, and now we have to find lock screen and security. Now, let's tap on encryption and credentials and at the very bottom of the list, we've got clear credentials options so simply tap on it tap on. Ok, if you are ready, if you've got a pattern or a pen then enter to confirm and as you can see, that's all the credential storage has been erased successfully. So that's all this is how to remove credentials in your lgk52. Thank you so much for watching.
