Raise up your hand if the fingerprint scanner on your iPhone or Android phone often fails to work on the first try, and you start to wonder if nature did not give you wrong fingers.
Relax, there are many reasons why the scanner may not work the first time.
- The tip of your finger does not fully cover the sensor.
- You have wet hands.
- The phone could not remember the fingerprint exactly when you first registered it.
- The implementation of the phone can make the scanner more sensitive, for example, if the software has more sophisticated security levels built in.
This advice does not help from all these, but it definitely helps.
If you are trying to unlock your phone so many times that you need to go back to entering the password, stop. Take a deep breath. And try this extremely simple solution that really works.
Register the same fingerprint two or three times. I do this with all the phones that I’m testing, and this makes the devices more agile when unlocking from the first time.
This is due to the fact that when you register your fingerprint in the phone settings, it is not always clear what parts of it are downloaded to the software. Nominally useful animation forces you to raise your finger to grab more of its area, but it does not necessarily reflect the data stored on your phone.
Scanning the same fingerprint more than once, you double or increase the chances that your phone will process a sufficient amount of data.
Of course, adding duplicate copies of prints will not solve your unlock problems if your hands are too wet to allow the phone to scan the imprint.
How to register multiple fingerprints on your phone.
Due to security reasons, most phones store a maximum of five fingerprints. The more fingers you scan, the higher the probability that the phone is unlocked by false triggering.
On Android phones:
- Open the Settings app.
- Click on Security.
- Select “Fingerprint”.
- Enter the PIN code.
- Click Add Fingerprint.
On iPhone with Touch ID:
Touch “Touch ID and password code”.
Enter your password.
In the section “Fingerprints”, click “Add fingerprint”.
Try it, and let me know how my little advice works for you.
