How to use Galaxy Note 4 finger scanner?

What can I do with Galaxy Note 4 finger scanner?

Samsung introduced fingerprint scanner in  Galaxy S5. So, Galaxy Note 4 finger scanner  is actually the second iteration of this feature.

Apparently, Samsung  did not highlight the Galaxy Note 4 finger scanner partially due to poor reception of this feature  in Galaxy S5.

In Galaxy Note 4, Samsung polished the finger scanner without dramatic change. Now, it works far better than that in Galaxy S5. But it is still not up to par compared to fApple’s Touch ID.

Galaxy Note 4 finger scanner allows you to:

  • Unlock the phone with your fingerprint. This is probably the most widely used function.
  • Verify your Samsung account with your fingerprints.
  • Sign in to websistes  with your fingerprints instead of typing password.
  • Send payments or access Paypal account with your fingerprints.

How to use Galaxy Note 4 finger scanner?

To use Galaxy Note 4 finger scanner, you must register your fingerprints on the phone.  The fingerprint info is save only on the phone, according to Samsung.

Step 1: Access Fingerprint manager

You can go to Settings–Finger Scanner to access the Galaxy Note 4 finger scanner settings.

Tap Fingerprint manager as shown below.

The system will tell you that  your fingerprint info will be saved in the device, not on any Samsung servers. This is to address the privacy concerns of some Galaxy Note 4 owners.

Step 2: Register fingerprints for Galaxy Note 4 finger scanner

You then can register your first fingerprint.

You need swipe through the home button downwards.

Of course, after you register 10 downward swipes, you can register upward direction swipes.

You cannot swipe through home button horizontally because of the two hardware buttons in each side of the home button.

Once finishing one fingerprint, you can tap Done to save the fingerprint info into the phone.

Step 3: Create backup password for Galaxy Note 4 finger scanner

When you try to save your first fingerprint info, you will be asked to set up a backup password  for Galaxy Note 4 finger scanner (alternative password).

This backup password can be used when your fingerprint is not recognized, for example, when your hands are wet. In other words, whenever fingerprints are accepted, this backup password can be used as well.

This password is saved locally on the phone.  You can only change or reset this password with your fingerprints or this password itself. Google account and Samsung account can NOT change or reset the backup password unless you reset the phone.

So it is important to write down this backup password, and save it in a safe place.

The security requirement for the backup password of Galaxy Note 4 finger scanner is 6 characters long  with at least one number and one letter.

If the backup password does not meet the requirements, you simply have to provide it again before you can confirm the password as shown below.

How to manager fingerprints in  Galaxy Note 4 finger scanner?

You can manage your fingerprints (e.g.,  register more fingers, delete fingerprints) in Settings–Finger scanner–Fingerprint manager.

To access fingerprint manager, you need authenticate yourself with your registered fingers, or with the backup password.

You can tap the keyboard icon to type the backup password if none of your fingerprints is recognized.

Once you enter fingerprint manager, you can tap the+ button to register more fingers. Galaxy Note 4 allows you to register up to 3 different fingers.

But actually you can use different fingers for each registration, i.e., you can use different fingers for the 10 strokes.  So, it is easy to register your 5 fingers without losing accuracy.

To manage the saved fingerprints, you can tap and hold the name of the fingerprint as shown below. This will make it selected.

Once the fingerprint is selected, you can tap the pencil icon to edit, or the dustbin icon to delete it. Both icons are in the top right of the window.

Another way to manage fingerprints is to tap the menu key (3 vertical dots) as shown below.

Then tap select.

Now you can select one of the registered fingerprints.

Once the fingerprint is selected, you get the similar icons of editing and deletion as shown above.

Why my fingerprints are not recognized  in Galaxy Note 4?

Sometimes, it is frustrating when your fingerprints are not recognized.

Some possible causes of the failure of Galaxy Note 4 finger scanner include:

  • your finger is too wet. Dry it.
  • you do not wipe through the home button. You need wipe though the home button. This can be tricky if you are using OtterBox like cases.
  • the part of finger tips is not registered. When registering your fingerprints 10 times, you need try different parts , especially for big fingers.
  • hardware failure.
  • internal software hiccup. You may reboot the phone to try again.

How to unlock my Galaxy Note 4 if my fingerprints are not recognized?

If, for whatever reasons, Galaxy Note 4 finger scanner refuses to accept your fingerprints, you can still unlock the phone through one of the two methods:

  • Use the alternative password (backup password).  On the lock screen, you can tap the keyboard icon to type the backup password to unlock the screen.
  • Use Android device manager to unlock the phone with your Google account.

Please note, your Google account can only unlock the phone. It cannot  reset the backup password for Galaxy Note 4 finger scanner.

If I forget the backup password for Galaxy Note 4 finger scanner, how to reset it?

If you forget the backup password (alternative password) for finger scanner, you can reset it with one of the following 3 methods.

  • Use your fingerprints. If your fingerprints are recognized, you can go to Settings–Finger scanner – change backup password to reset the backup password by authenticating yourself with your fingerprints.
  • De-register  all fingerprints. Of course, this also requires that your fingerprints are recognized. In fingerprint manager, you can delete all fingerprints. Once all fingerprints are de-registered, the Galaxy Note 4 finger scanner is reset. You can register your fingerprints again and setup a new backup password.
  • Factory data reset. If you forget the backup password and none of your fingerprints are recognized by the Galaxy Note 4 finger scanner, you probably have to reset the phone. This essentially erase all your data and settings on Galaxy Note 4. So, you should always backup your data before resetting.

Can you use Galaxy Note 4 finger scanner now?

  • I just put the fingerprint scanner on my phone. I have 2 issues:
    1. When I click on the keyboard icon to put in my password nothing happens. My phone restarted and now I can't get into my phone because you have to use the backup password and I can't get the keyboard to appear.
    2. The fingerprint scanner doesn't work consistently and I want to go back to not using it but I can't figure out how to cancel it.

    • 1. Did you disable Samsung keyboard? When you set up fingerprint, you were asked to set up password/pin. You can only use PIN or password to unlock the phone after a reboot. Fingerprint is only a secondary method since Marshmallow because the fingerprint data must be protected by PIN/password.
      2. You can delete all registered fingerprints, or choose not to use fingerprint to unlock phone in fingerprint manager.

  • I bought the note 4 and it won't allow me to register my fingerprints I get an error tells me to restart the phone and try again iv done that a hundred times iv cleared the cache and force stopped it iv factory reset the phone it still doesn't work I loved my s5 but hated the s6 edge so I went with the note 4 without the use if the fingerprint scanner I may as well have reverted to the s4

  • Thank you so much for your post! I've been locked out of my phone for the past six days because when I was in power saving mode, the fingerprint option somehow disappeared and my Wi-Fi and I were both off. Because of this, I was unable to sign in via my Google account. I kept entering what I believed was my backup password and all different combinations of other passwords I use for my laptop and email etc. It wasn't until I read your post about "the security requirement for the backup password of Galaxy Note 4 finger scanner is 6 characters long with at least one number and one letter" that a lightbulb went off. My password was correct, however I had omitted the one digit I placed in there. I've been so stressed out for the past week and this is a huge relief. I really feel for anyone who's going to this because everywhere I turned, I was only given the grim choice of having to wipe my phone which was never an option. I hope this helps someone else. Good luck to all !

      • Hai. .if I open the finger scanning it will showing the fingerprint bt if i try to open its need the backup password. ...bt i forgot my password bt I need to open the lock by my finger........it's always showing backup password
        Plzzz help me

        • Is your Note 4 running on Lollipop out Marshmallow?

          If in Marshmallow, it doesn't use backup password. You need set screen lock as pattern/PIN/password to use fingerprint.

  • helo all
    please help me

  • When trying to access private mode using fingerprint it doesn't work (had glue on my finger) and then your prompted for password. Password has been lost and it no longer gives the option for using my fingerprint. Please answer this question: IS THERE A WAY TO GET THE OPTION BACK TO SCAN FINGERPRINT?

    • if your fingerprint can be recognized. you can change backup password in Settings-- finger scanner with your fingerprint.

      • AGAIN, it no longer gives me the option to use my fingerprint it goes right to asking for a password (even in settings). IS THERE A WAY TO GET THE OPTION BACK TO SCAN FINGERPRINT?

        • It depends on firmware (your region). In some regions, it may switch back to fingerprints after clearing cabbage and a few reboots. But in other regions, it seems it will not revert back until it's updated or reset. You may check with local Samsung service center to find a way out.

  • Every time I swipe my finger and it can't read my print I get a vocal message swip slower ir no match. How do I get rid of that verbal message

  • I just unlocked my phone! My phone was locked out at the lockscreen and for some reason I was not able to use the fingerprint scanner and it keeps prompting me to unlock with backup password. I was going to factory reset password but I found a solution from the internet that is to use Find my Mobile ( from Samsung ) to unlock it. Below the link,
    https://findmymobile.samsung.com/login.do

    I was quite surprise it actually worked!!! Hope this helps!!

  • as of a little while ago my phone wont recognize my fingerprint and its saying the backup password is incorrect. i have no way of unlocking my device while its doing this, how can i fix it?

  • Thanks but i don't have samsung account on my phone, and did not received any offer to unlock by Google account, is there any other option?

  • Hi, my note4 fingerprint option disappeared and i forgot my back up password as well, can you plz help me how to unlock my phone without losing my data

  • Hi Goodmorning, My Note 4, since today morning onwards got problem with fingerprint unlock, but i could able to unlock the phone with backup password. Then i wanted to change the finger print unlock mode. then I tried in setting, i tried to swipe my finger, then its says Not Match, then i used backup password. Then there an error message saying.. 'incorrect backup password', but i used the same backup password to open the device in the first place. Can you please suggest how to rectify this problem. Thank you

    • Unlikely. You probably entered the wrong password.

      Anyway, you can try to add a Samsung account, enable find my mobile, then reset the screen lock from Samsung find my mobile website.

  • Hello,

    I have a standard white samsung galaxy note 4. I have 3 of my fingers registered to unlock my device, I however did forget my backup password. The problem I have is that no matter what I do the phone always sends me straight to the back-up password way of unlocking my phone, I have no way of using my fingerprint scanner. the fingerprint scanner option doesn't even come up. I tried turning my phone on and off again, nothing happened. I tried letting it run out of battery and then charge it again, nothing happened. I have tried removing the battery while the phone is turned off, and then again removing the battery when it was turned on, nothing happened. After all my attempts it would always jump straight the back-up password option. I have also tried to do something using the android device manager, that also didn't work. What do I do?

    • You can try random password a few times. In some regions, it will then allow you to use Google account to unlock the phone or reset back to fingerprints.

      Android device manager note can only lock it wipe device. It cannot unlock devices due to legal reasons. You can try Samsung's Find my mobile services to unlock the phone with your Samsung account if you added the Samsung account to the phone before.

  • Hi, I cannot remember my back up password for the finger print scanner, the android device locator, I changed the password but this did not work. Am I screwed? Is the re-set the only way? Being trying it for a while now!

  • So I have the Note 4, and I use the fingerprint scan for my lock screen, and it works fine. But oddly enough, sometimes when I wake the device, I see the phone, lock, and camera icons on the lock screen, and if I just swipe across the screen, the device unlocks without prompting me for a finger print. Other time, it will prompt me for my fingerprint as soon as I unlock the device. Anyone have any ideas?

    • You can access camera from Galaxy Note 4 lock screen without unlocking the phone. This is the purpose of camera shortcut in the lock screen. But you cannot access other apps of the lock screen security is fingerprint.

      • I get that, but it unlocks the entire phone. What I mean is I swipe across the middle of the lock screen, not any icons (camera, etc), and the phone unlocks and loads the homescreen. Basically, I am bypassing the fingerprint security by simply swiping the screen.

          • I think that may have been it. It was enabled by default, so I've disabled it. I also set it to lock when the power button is used. Seems to have corrected the behavior. Thanks!

  • Here is a simple question. If the finger print scans are held locally on the phone, and samsung offers no master reset option---------------then why other than tracking users for the Samsung and the NSA , would you even need to register a finger print ??? Snowden warned everybody about mass spying and this is yet another way to verify that it is "you" that was using your phone. This type of information will be used against people who the government decides has committed any type of crime. So your own phone will testify against you. Big brother in the palm of your hands !!!

  • Fingerprints is currently set as the screen lock type for at least one of the following: encrypt device Exchange active sync

    Select another method and try again.
    This was the message I get when I want to deregister the fingerprint

  • ok so I did something bad. I put in the wrong fingerprint wrong until my phone locked and I thought it was going to just give me 30 secs and then I could try again but yah that didn't happen and I don't know my back up password not even my gmail that Verizon created for me. aahhh idk what to do! I really do not want to reset my phone! Help me Please!!!

  • Go to settings, security, and clear credentials. Once complete you can go and remove or turn off you finger print scanner.

  • Hello. .I am using finger print lock. But now I want to go back to Swipe screen mode. .but when I checked settings. ..in that it shows disabled by administrator . .encryption policy or credential storage. How to go back to old mode

    • Very likely, you have one or more Exchange email account, or have a VPN account. If these present, you are not allowed to use swipe.

      • I used the fingerprint lock for the private mode in my galaxy note 4 . But now all of a sudden it doesn't recognize my fingerprint nor does it accept the backup password.PLEASE HELP I donot want to lose the files in my private folder

        • There is no official way to reset the password for private mode. You have to reset the phone: this means you will lose the folder.

          You may try to backup the phone with Kies on a PC to see whether you can find these files.

  • The fingerprint function is a disaster for me. It will not recognize my one fingerprint, so I can't get into the menu to stop fingerprint identification. I suspect women have more problems as our fingerprints are not as prominent. This feature should be removed as it is horrible and creates frustration and work.

  • I use att note 4 but could not register my fingerprints even I tried steps again and again even I reboosted not 4 several times. I thought that could be a hardware failure and how should I deal with this problem.

  • My backup password does not work. I think my finger was just wet. I would like to go back to scanner. How can I switch back from backup password to fingerprint scanner? Also, Device Manager does not unlock the phone. It only locks it. And when I enter a new password. It informs me my phone is already locked, no need to change password. I want my scanner back. I am sure it will work.

    • Android device manager allow you to set a new lock. To be precisely, it is a reset of the lock. so you can use new pin unlock the phone. The word in the page is a bit misleading.

      • SIMON!!! HELP PLEASE!!! I am so desperate and frustrated! Is there any way at all to switch back to fingerprint scanner from backup password? I cannot remember my password at all.. I tried ALL combos and ALL password that I can think of and it's not working at all!!! I am in my 70th times now! I know if it went back to my fingerprint scanner it will work. I was doing laundry last night and my thumb was cold and it didn't recognized it and so it went to backup password. I did go to my ADM account and the password that I put in (6 numbers) is NOT working to unlock my... it is still saying Incorrect Password. Then this morning I went to AT&T and they are no help at all. They said that they cannot unlock it for me and directed me to Samsung Customer service office so I went there and the tech guy told me that since Google updated, ADM doesn't work anymore to unlock the phones. Is that true at all??? Is that why I cannot unlock my phone using my ADM account? I hate to do a Master Reset. I have tons of entry on my calendar (which I didn't sync) and Colornote memos (which I haven't sync yet) and tons of recent vacation pictures on my phone. AARRGGHHH!!! I am going to cry!!! Please help!!!!

        • Yes, Google updated the android device manager. You cannot reset the screen lock with android device manager. It can only lock the screen if it's unlocked.

          You can try Samsung Find My Mobile service if you have a Samsung account on your note 4. It can unlock your phone. Please follow this guide http://gadgetguideonline.com/galaxys6/samsung-galaxy-s6-guides/how-to-unlock-samsung-galaxy-s6-and-s6-edge-if-you-forget-the-screen-lock-password-and-your-fingerprint-is-not-accepted-either/

          • HI Simon... Unfortunately, I cannot look into my Galaxy Note 4 device for this Samsung Find My Mobile Service because it is locked. (By the way, I am in my 100 times of trying a password :( ).. I do have a Samsung account and I registered my Note 4... but I cannot do into my device for this to work :( .. Any other suggestions please???

          • You can access find my mobile from any pc. Then choose unlock. Can you log in Find My Mobile from your pc with your Samsung account?

            There are no other ways to unlock the phone without resetting it. This is the purpose of the lock. Otherwise, anyone with the phone can easily access your personal files.

            If you think you can still have chance to remember the password, reboot the phone, have a cup of coffee, walk 1km, then go back and try gain. Don't stress yourself to hard.

  • Well now, Tiana, aren't you just the smartest thing ever!!! It worked!!!! I don't know how you knew to do this, but I am so glad. Thank you!!

  • I only have gmail and I just checked VPN and it says No VPN's. Any other possible causes? Thank you.

  • Not sure what that is exactly, but what can I do to find out if I have done this and how to reverse it? Very appreciative of your help.

    • If you have either VPN or Exchange (email) account, you cannot choose swipe. You need remove them before swipe is available.

      Did you set up any email accounts in email app (not gmail)? VPN can be found in Settings--More networks--VPN.

  • I want to turn off my finger scanner but my Note 4 will not let me. I went to Lock Screen, then under Screen Lock it says 'secured by fingerprints'. I hit that and it prompts me to scan my fingerprint. When I do this, it goes to the list of security options. The options Swipe and None are not allowing me to select them, they are grayed out and both say turned off by administrator. The others (pin, partern, etc) will allow me to select them. What do i do to get this finger scanner turned off? I don't like it.

    • Very likely, you added some exchange accounts or vpns. They will not allow you to turn off the security on lock screen.

  • Everytime i go to press the fingerprint scanner button it says that theres an error and that i have to restart my phone. But even when i already restarted the phone like 20 times it still says the same thing. What am i doing wrong!?

    • In that case, you can unlock the phone with the backup password. Disable fingerprint for lock screen. Restart the phone, set the lock screen to fingerprint scanner, then try to lock and unlock with fingerprints.

  • Hi, the other input is swype . I checked the android device manager is activated. Can you tell me how I use it on my PC?
    Thanks
    Mark

    • On your pc, just Google Android device manager and follow the link. After logging in, you can locate the phone, ring your phone or unlock the screen.

  • I have been using my finger print scanner on my note 4. But sometimes it does not recognize my prints.Then I have to wait the 30 seconds and hope it works the next time. My big problem is that if my prints are not recognized I try to select enter backup password. All I get is a pop up saying choose input method. I choose samsung keyboard. I am then caught in a loop, I do not get a keyboard to enter my password.

    • probably, you have installed other input method or keyboard. You need set one as default so that it will ask you to choose.

      For the fingerprint scanner, you actually can use all of the 10 chances with different fingers. With 3 fingerprints saved, you can register about 5 fingers

      • I do have the samsung selected as default. As to using different fingers. Are you saying as it asks for the 10 different swipes I can swipe say my thumb 4 times ,my 1st finger 3 times and my 3rd finger 3 time's? Then I would be able to unlock trying the three different fingers? I am still scared about not being able to get the chance to enter my password. I might get locked out of my phone then what do i do?
        thanks
        mark

        • For the input method, what's the other input app?

          For registering fingerprints, yes, you can use different fingers for one fingerprint.

          If you cannot unlock the phone, you can use Android device manager on your PC to unlock the phone. By default, it is on. You can check it in Settings--Security--Device Administrators.

          Anyway, if you have no confidence on finger scanner, you should use other screen security settings (e.g., PIN or password).

  • I have registered my finger print but unable to make the screen lock secured with the Fingerprint scan. In fact, when I tried to select the screenlock, The Fingerprint section is greyed out with a message that says "Turned off by administrator, encryption policy or credential storage." How do I make my screen lock secured with my Fingerprint instead of PIN. Thank you very much for your help.

    Tim Thai

      • Yes. you are right, Simon. Is there a way to get around? This Exchange account is forcing me to use 6 digit PIN instead of 4 and that is really drive me nut sometimes. Thanks.

        • There is no workaround as i know. Micosoft programs always require excessive permissions. Exchange is the worst. It may control your phone remotely, erase all data in the phone.

          Unless the phone is given by your company, you should stay away from exchange account. You can add the account as normal email account. Of course, you will lose the exchange calendar and directory.

          Anyway, it's up to you and who owns the phone. If you just use the email feature, add it as a normal email account.

          If the phone is configured by the IT staff, you cannot do anything.

  • Hi im having trouble with my phone since 3days the backup password is not working, please help me dont want to delete all my files can't have access to my phone.just received call

  • What if I want to temporarily want to not use the fingerprint scanner to unlock my phone. Can I turn it off without having to reinstate my fingerprints and pass word??

  • I have a AT&T Note 4, I tried to use the fingerprint scanner to unlock my phone after I registered my fingerprint and backup a password. The fingerprint scanner didn't recognize my thumb print after the phone is turned off, and I have to use the backup password to access my phone, how can I reset this finger scanner if it don't recognize my print? Please help!

    • You can de-register your fingerprints (with your backup password) as shown in "How to manager fingerprints in Galaxy Note 4 finger scanner" part of this guide. In Settings --Finger scanner--Fingerprint manager. You can authenticate yourself with the backup password. Then you can see the list of registered fingerprints. Tap and hold any of them to select it. You can select more. Then tap the delete (dustbin) icon in top right to de-register (remove the fingerprints). You can always register fingerprints again.

  • Ok, My wife has a note 4 and started using her finger scanner. Everything was going great. Then tonight, she went to scan her finger to unlock her phone and it would not recognize her finger. So she entered her backup password. That allowed her to access the phone. I advised her to go delete her finger scans and re-scan them. So she accessed the Finger Scanner menu under settings and had to put in her backup password, the phone keeps saying that the backup password is incorrect. How is this the case when it was the correct backup password for her to access the phone? PLEASE HELP!!!

    • i want to deactivate the password feature every time at the lock screen. i was able to get rid of the finger scan but now it asks for a password each time. all my options are greyed out. i've tried the clear credentials and nothing. my phone is encrypted does that have something to do with it? can you have the finger scan for websites only and not the lock screen?

      • If the phones is encrypted, you must set a password for the lock screen. It doesn't make sense to encrypt the phone with unlocked screen. Remove the encryption if you need set lock screen security as none or swipe.

    • Yes, it should be the backup password.

      Anyway, if you can still unlock the phone with the backup password, you should set screen lock to something else.

      • What if I want to delete my registered fingerprint? I have gone to fingerprint manager and it won't let me delete it after I select it! What do I do, I hate this thing....please help!
