Many Android users using the fingerprint sensor instead of face unlock. They are facing some trust issues in that lock, even if it is fast compared with the fingerprint lock. Many users complained that the sensor on their device is slow to respond. Well, the reasons for the delayed response of your fingerprint sensor has been discovered. We are going to share how you can speed up your device’s fingerprint in a natural way that does not require any hard work. In this article, the steps are 100% safe and do not have any side effects like third party apps or devices slow. Before we proceed further we will discuss the possible reason(s) why your fingerprint is taking time to respond.


Fingerprint sensors are designed with different technologies; there are ultrasonic scanners,  optical fingerprint scanners, capacitive scanners, and in-display scanners. However, irrespective of the technology used for the fingerprint sensor on your device. If the sensor seems to be slow to respond to touches, follow the steps below to speed it up.

How to Improve the recognition speed of your device fingerprint sensor

Method One- Remove Extra fingerprints

If you have Low RAM device then this method can be helpful. Some people set up the whole fingerprint recognition slots, which is about four. May be using up all the fingerprint slots can cause the response to be slower than expected. But some people have confirmed that after they removed some slots, their sensor started responding much faster.

Some smartphones allow you to setup up to four or more fingerprints on your device. Set only two prints for Left and Right hands. It is efficient to use two imprints. So, that when you can’t reach your mobile with one hand, you can use other:



  • At first visit your device settings menu
  • Now search for the fingerprint settings option
  • Delete all the fingerprints
  • Setup new fingerprints
  • When setting up the “one” fingerprint, make sure you add up to 40% of each thumb, then 10% of each tip of your finger.

The last step may seem quite difficult to understand; however, here’s the explanation.

You have to place a finger on the sensor a couple of times before you set up a fingerprint. Thus, you should keep putting each of your thumbs until the fingerprint scan is about to be completed, then you can add the tip of your fingers.

Method Two: Add Extra Fingerprints

This Method and the above Method can be a little bit Opposite thoughts. New mobiles have enough RAM to handle a lot of apps. If your mobile is an In-Display sensor mobile or flagship device, and it is slow in recognizing your fingerprint, this method will help you. Lots of people have confirmed that it works for speeding up your fingerprint sensor. The way is quite simple; here’s how to do it.

It has been confirmed that in some device if we added multiple fingerprint sensors, It can enhance the recognition.

Add more finger prints


  • Go to your Settings >> Security >>Finger Imprint
  • Then delete all your current fingerprints
  • Set up Two prints for each thumb (Left x 2 and Right x 2).

Method Three: Remove Dirt

  • Clean the dust on the surface of your fingerprint sensor (If it is a Physical Sensor)

Dust on the surface of your sensor is also a primary reason why the sensor is responding slowly or not recognizing your fingerprints. You’ll surely solve most fingerprint issues by cleaning the sensor’s surface. Clean with a less wet cloth. This method is only applicable to Physical sensors. If your mobile has an In-Display fingerprint sensor, you may frequently clean your screen.

Method Four: Clear Cache

Finally, the best way to speed up your fingerprint is to clear junk and cache on your device. Lots of junk and cache files can cause a smartphone to act slowly. You can try clearing the cache files and junk on your device and see if your fingerprint will respond as you expected.

To Conclude:

If you follow the above steps wisely you can enhance the speed of your Fingerprint sensor. If your mobile has In-Display Sensor, and you are using Tempered glass, you should check it is supports the sensor or not. The issue happened when Samsung Galaxy S10 devices are released. Make sure you don’t install any third-party apps to optimize this process other than in-Built apps. So, We should optimize the best way to use it.
