Why can't I open the mobile phone with the finger print of the dead person?

After the death of a person can the mobile lock be opened with the help of his fingerprint.

 Nowadays privacy is also being challenged by the fingerprint sensor of the mobile. Its main and an interesting question is whether the lock of a person's mobile can be opened with the help of his fingerprints after his death?

 Friends, first of all, know that every person has his own fingerprints, which are completely different from others. Even if the children are twins, their fingerprints are different. Since everyone's fingerprints are different, it is very secure in terms of security. For this reason, fingerprint sensors, apart from phones, are widely used in many government and private institutions.

 A person's fingerprints do not change even after death. But it remains active for a short time after death. Once the body begins to decompose, the fingerprints also begin to decay. The body usually begins to decompose within 24-72 hours. Generally a person's phone cannot be unlocked after their death. Because, the fingerprint sensor used in other devices, including mobiles, not only traces the outer coating of the fingers, but also traces the electric impulses flowing between the fingers.

 In such a situation when the finger of the dead person is placed on the fingerprint sensor of the mobile, the sensor does not feel any electric impulse on the finger. Neurons in the body also stop working due to death. In such a situation the electric impulses stop. So the fingerprint sensor cannot unlock the phone.
