One of Samsung Galaxy S4's coolest features is the Face Unlock. Once activated, your phone will scan your face, and when it's been matched with the face on file, your phone will unlock itself automatically. However, this may not function properly, as different lighting may alter your face, making recognition difficult. Should you feel the need to change the face unlock with a new face, for whatever reason, you can simply disable face unlock. Once disabled, your phone will delete the stored face. You can then setup a new face unlock.

How to Unlock Samsung Galaxy S4 if You Have Forgotten Your PIN

In many cases, Samsung Galaxy S4 does not give you the option of entering your Gmail account ID and password to bypass the lock screen. If you have forgotten the PIN, try it several times until it gives you the option to select "Forgotten Password." To prevent this from happening, you can send the PIN to your Google account in an email when you first set the PIN, so even if you can't remember it, you will have the information in an email messages.

Was this helpful? Yes | No | I need help

If you are using the pattern, try it around five times, and if you still haven't done it right, you will be given the "Forgotten Pattern" option. Tap it and enter your Google ID and password to bypass the lock screen. If, for whatever reason, the option of "Forgotten Pattern" never comes up, try these steps:

Broken S4, need help accessing the photos?

I went on a trip today and when I came back my S4 was broken, I also have a pattern lock on it... How can I get my files back

How is the phone broken? If it's still functional, you might have a chance to retrieve your photos. Download and install Samsung's Kies sync software on your computer. You can find the download here:

Was this helpful? Yes | No | I need help

http://www.samsung.com/us/kies/

Connect the phone to your computer and hopefully you can retrieve your photos with the phone on the pattern lock screen.

If that doesn't work, you can attempt to guess the pattern until the phone prompts you to enter your Google account info. At this point, you can get back into the phone with the Gmail info you used to set up the S4. In case you've forgotten that info also, you can go through a recovery process here:

My face unlock failed too many times and I do not know the backup pattern or my email address?

Galaxy S4 won't unlock please help

If you cannot remember your email information, and you are not connected via WiFi or data connection, you will have to do a Hard Reset on your S4 to be able to use it again. Do the following to do the Hard Reset:

Was this helpful? Yes | No | I need help

  • Turn off your phone.
  • Press the following:

- volume up

- home

- power

  • When phone vibrates, release power button.

I cannot remember the PIN that I entered during setup of Face Unlock. What will I do now?

If you are unable to remember your PIN, the best thing to do is unlock your phone using the face registered during the Face unlock set up. If the phone does not recognize it, try to unlock it at the same location and time as when you set it up, as artificial lighting and ambient light conditions affect the way your phone interprets the face.

Was this helpful? Yes | No | I need help

If the phone fails to recognize the face, the only option left is to perform a Clean Data from Samsung Galaxy S4 by Reset. The reason why Hard Reset is the only option is because Samsung locks your phone for your own protection. Performing a Hard Reset will erase all the data on your phone. This means that any application data, progress and phone cache will be deleted. To Hard Reset your Samsung Galaxy S4 you can follow these:

Was this helpful? Yes | No | I need help

  • Turn On and Off the Samsung Galaxy S4 by pressing and holding on the power button until the phone vibrates indicating that it has been completely turned off.
  • With your device turned off, simultaneously press the Power Button + Home Button + Volume Down key for 3 seconds or until an Android icon appear. Release all three buttons once the Android icon shows up.
  • Using the Volume keys, navigate to the option: Wipe Data / Factory Reset and press Power button to confirm.
  • Using the Volume keys, navigate to the option: "Yes -- delete all user data" and press Power button to confirm.
  • Galaxy S4 will now reboot and will restart. Your phone is now reverted back to factory settings.

I had lost my pattern so I could not change my face detector what should I do?

I also having problems to use face detector in darkness./..... its my marriage gift so its very important for me please give ma advice LOL

If you forgot your pattern, you can always gain access to your Samsung Galaxy S4 with the use of a backup PIN. You have six available options for screen locks on your device that includes Password, PIN, Face and Voice, Pattern, and Face Unlock. You can activate every single one to ensure multiple layers of protection and security on your phone.

Was this helpful? Yes | No | I need help

You will really have problems using the Face Detector in the dark because it needs an indoor spot to work, which should be neither too dim nor bright.

To change the screen lock settings:

  • Go to "Menu".
  • Click on "Settings".
  • Select "My Device".
  • Tap on "Lock Screen" and "Screen Lock".
  • Key in the needed security unlock information.
  • Click "Continue".
  • Choose the security lock feature you would want to customize or change, and then follow the steps for that screen lock feature.
