5 tips to optimize the operation of the fingerprint scanner

The fingerprint scanner under the screen has improved a lot over the years. We explain how to optimize the performance of your in-screen fingerprint scanner tips.

1. Read reviews

When you buy a new phone, you may not always be tempted to attach great importance to the quality of the fingerprint scanner under the screen. You will probably check whether there is one, but not everyone takes the time to check what the experiences of a reviewer are. The quality of the screen, the camera or the performance seems a lot more exciting with a new device, and admittedly, they are.

Nevertheless, it is worthwhile to explicitly read reviews about the fingerprint scanner, and in reviews on tech largest, it is always a separate point that is discussed together with any facial recognition.

My worst experience I ever had with a fingerprint scanner was, for example, with the scanner on the back of the Samsung Galaxy A6 (2018), and in that case, I stated that very clearly in the review.Take the time to set fingerprint scanner

Our best experiences were again with the scanner of the OnePlus 8 series that works very fast, or that of the OPPO Find X2 Pro and Find X2 Neo because it also has an extra-large scanning surface.

2. Take the time to set

If you have a brand new phone, your enthusiasm may make you want to complete the setup as soon as possible. Nevertheless, it is advisable to take the time to register your thumbprint with the in-screen fingerprint scanner.

During that process, you have to lift your finger several times and place it on the sensor. Lift and reposition slowly so that your scanner has time to properly capture each position. Depending on the phone you are using, you will also be asked to scan a different zone on your finger each time.

That is the best way to optimize accuracy. In many cases, you will also be shown which area of ​​your finger to scan, and follow those guidelines as well.Make sure that the sides have been scanned particularly well, and each time apply light pressure on the screen.Register the same finger twice

Some phone manufacturers work with ‘self-learning’ software that also improves the performance of the fingerprint scanner by scanning, but make sure you give your phone as much data as possible to work with from the start.

3. Register the same finger twice

This is a tip that can give mixed results as it can really make a difference with some phones and not others. Fingerprint scanners are often sensitive to the angle in which you place your finger on the sensor.fingerprint scanner tips

If you first set up your fingerprint while holding your phone in your hand, it might be wise to register that same thumb a second time, but when your phone is on the table.

4. Have patience

This point may sound simple, but it’s important to give yourself and your phone sometimes. As mentioned earlier, the operation of a fingerprint scanner can be self-learning. As you unlock more, your smartphone can use that data to improve accuracy.

On the other hand, muscle memory also plays a role with fingerprint scanners under the screen, more than with scanners on the back. With a new phone, you should also give yourself the time to get used to your in-screen scanner so that you learn to place your finger properly. So don’t panic if your scanner isn’t as accurate or fast as you hoped at first.

5. Reset your fingerprint

If there is no improvement or your scanner is really underperforming, then you may have gone wrong with the setup. In the settings, delete your fingerprint and register it again as described in the second tip.
