What can I do with this sensor on my Samsung device?

Currently, many applications in the digital world have introduced the fingerprint detector as part of their operation, whether it is to make payments, unlock the phone, control access to the applications installed on our mobile devices or simply answer a call.

Other features that the sensor has is that it prevents people from accessing the information stored within these devices and lowering the notification window of the phone .

Prevent people outside you from checking your mobile

It is common that when we are in a meeting, be it family, work or friends, we usually leave our mobile phone within the reach of anyone, with the consequence that it can be manipulated by third parties, giving them full access to our information .

 

With the activation of the fingerprint detector in our Samsung mobile phones, we will be able to prohibit entry to the phone records, since once the fingerprint is configured, we will need it to be able to unlock the device.

Pull down the notification window of your phone

The phone’s notifications window is a quick access that is used by sliding the screen down and where we can see if we have something pending, such as a message notification, interactions from a social network or simply an update notice on our phone’s system.

To prevent outsiders from seeing these notifications, we activate the fingerprint sensor, since with this function, in order to access this window, we must initially  unlock the phone .

Is it important to know the model of my Samsung to locate the fingerprint sensor?

The models that integrate this sensor are classified as mid-range and high-end phones, Samsung integrates this function from the Galaxy A10 model , but something that we must take into account is that these sensors are not the same in all devices .

 

That is why it is important to know the model of our mobile phone to know where the fingerprint sensor is located, either on the side, on the screen or on the back of the phone . Below we present some Samsung models that integrate fingerprint sensors and where they are located.

  • Samsung Galaxy A52 5G: this model integrates the fingerprint sensor at the bottom of the screen.
  • Samsung Galaxy S21 Ultra: the sensor is located under the screen.
  • Samsung Galaxy M32: a mid-range phone that has a fingerprint reader on the power button.
  • Samsung Galaxy A42 5G: this model has a fingerprint sensor at the bottom of the screen.
  • Samsung Galaxy A22 5G: The phone has the sensor on the power button.
  • Samsung Galaxy z Flip 3 5G: this device integrates the fingerprint reader on the right side.
  • Samsung Galaxy A03s: this model has the sensor on the right side, right on the on/off button.

How do I activate the fingerprint sensor on Samsung?

The fastest way to unlock the phone is through the fingerprint sensor, that is why here you will learn how to activate this functionality on your Samsung devices.

  • On the screen of your phone, slide one finger up or down, with this you access the ‘Applications menu’.
  • We locate and enter ‘Settings’.
  • We slide the screen until we find where it says ‘Biometric data and security’.
  • We enter Fingerprints’.
  • We give you continue.
  • A warning message will appear on the screen, we accept it.
  • Immediately it appears on the screen to scan the fingerprint.
  • We are located where the fingerprint sensor is on our device.
  • We press our finger against the sensor and remove it when the percentage rises, we repeat this step until we get a completion message and we click done.
  • Finally, we enable screen unlockby sliding the switch to the right.

The steps that we have just presented to you are generic, so you can follow them on any Samsung device to activate this function.

For what reasons does a fingerprint sensor stop working?

There are several reasons why our fingerprint detector stops working, by following the checks that we are going to present below you will be able to identify the possible causes of this failure.

  • Make sure to use the same finger that you registered the fingerprint with at the beginning.
  • Check the state of the fingerprint detector, this means that it is not scratched, dirty or damaged.
  • If you use a screen protector, check that it is not in poor condition(scratched or dirty), this causes the fingerprint to not be read correctly.
  • Check that your hands are not wet, have excess body fat or any skin care product.
  • You are not pressing your finger well against the fingerprint detector, try to make it completely cover the entire sensor.
  • In case you have a scar on the finger with which the fingerprint detector was configured, you may have to proceed to delete the previous fingerprint and re-register a new one.

Another uncommon problem in the fingerprint detectors of your Samsung mobile devices are the updates that the company makes , for this error we just have to wait for it to be corrected by the Samsung company.
