Why Fingerprints do not work after restarting mobile phone ?

I have been asked a very interesting question that when I restart , reboot my phone , it opens  with the pattern or  password and pin code , Not open with a fingerprint ?

Why does this happen?

If seen, then you have kept the fingerprint lock and if you open that first time after restarting your mobile , then it should be opened with the fingerprint, but it doesn't happen .

We going to talk about it.

So guys, first of all your biometric data is more valuable than your password that's attached to your phone.

  • You know that our Aadhar card works with all biometric, works with fingerprint and fingerprint works in many places, works in like banks and security at different places.
  • Fingerprint is also considered as a signature's subject. 

You'll know that the person who does not know how to sign, then they do thumb means fingerprint is very important thing and it's different for every person .

  • To save lots of your biometrics, first of all, it asks for the password, because it's going to be possible that you can even touch the fingerprint  means that somebody can hold your thumb and unlock your phone.
  • But if there's a password then you may not tell the password or you are in a state of unconsciousness.
  • And in the worst case, what do you know if someone lifts your thumb for unlocking your mobile , So it is one of the reason behind this screen lock does not open with the fingerprint after the mobile is restarted

            Why Fingerprints do not work after restarting mobile phone ?

  • Second thing guys,  it's like that you simply need to remember your password or the passcode or the pattern it's because how we unlock our phone whenever we do it with our fingerprint in everyday time .
  • And there comes a time , we will forget the Pattern or the password, because the thing that we don't use , we continue forgetting with time.
  • So , screen lock does not open with the fingerprint after the mobile is restarted

How Encryption works on mobile phone


  • Another reason for this is often that once you unlock your phone with fingerprint, that access won't go to your encrypted phone meaning your phone is encrypted. 
  • If something is encrypted, it works in Android in the same way that the encryption that opens for the first time or the form that opens is from the password authentication or your pattern authentication. It doesn't open with fingerprints.

How does fingerprint work? 

Do you know how fingerprint works?

  • Your phone has a fingerprint scanner that doesn't scan your entire finger.
            How does fingerprint work?
  • You know what you add fingerprints in it, you rotate it separately and give it to you from different angles, then read it, then whenever you're unlocking your phone with fingerprint scanner then a small ring The fingerprint of the part receives your phone, it doesn't complete, but it goes to the system and your mobile in unlocked.
  • Fingerprints are matched to both of them and any part that matches, then Your phone is unlocked instantly

In the United States, there's a rule that if the police wants it, then they forcefully can touch your thumb, because the law says that they cannot ask for a password or pattern.

Therefore, to make it more secure, only the password or pattern ask with starting on your phone. 

Fingerprint doesn't work because fingerprint is more valuable than your phone.
