Fingerprint Scanner

As smartphones are evolving, so is our method of dissemination of information. All of our data is now consolidated in a single place in the palm of our hands. With this accumulation of data, comes a grave concern to protect it.

Smartphones nowadays practically store a virtual profile of your personality which you’d definitely not want to get into wrong hands that’s why smartphones come equipped with security options.

Apart from iPhone X and a bunch of other phones, almost every phone today is loaded with a fingerprint scanner and as fancy and gimmicky it may seem, it is not the safest option to protect your precious data. Even today the most reliable option to protect your data is a pattern or a pin.

Fingerprint Scanner Test

We recently tested some of the phones to check whether the quality of the fingerprint scanner is as refined as the companies claim. These phones included budget devices, mid-rangers as well as the premium flagships from different companies.

The test included the enrollment of fingerprint in any specific device. While registering the fingerprint, we noticed that there were two major flaws, one of which was seen only on budget devices like Xiaomi Redmi 4X and Huawei Y7 Prime 2018 while the other haunted even the most premium phones like the Huawei Mate 10 Pro.

To our surprise, not only did the budget phones but the flagships also came short on their claims and shockingly produced poor results in terms of recognizing fingerprints.

In budget devices, no matter how the phone instructs you to move your finger between the touches, it registers your prints even when you don’t do so. Though this may not seem a big deal to some of us, it certainly denotes that these scanners are nothing but a gimmick and are very vulnerable.

You might think of it as a huge threat to your privacy but wait till you know about our second test which also included high-end phones. You may already know that its a scientifically proven fact that all our fingerprints are unique and no two can ever be the same. Sadly, in all our phones that we tested, we could register all our fingerprints in a single reading.

Resultantly, the phone recognized all the 10 fingers as one and unlocked with every finger. Not only that but during the test, the phone registered the fingerprints of two persons as one which allowed it to unlock with both.

Phones Included in the Test

We tried to justify our findings by including phones from all the brands and all price categories. Every phone that we got our hands on, exhibited the same behavior. Although we used more than two dozen phones for this test, some of them are listed below.

  • Huawei Mate 10 Pro
  • Honor 10
  • OnePlus 5T
  • Samsung Galaxy A7 (2018)
  • iPhone 5S
  • iPhone 6
  • Xiaomi Redmi Note 5 Pro
  • Xiaomi Redmi 4X
  • Nokia 8
  • Huawei Y7 Prime 2018

This really shows how many loopholes does this feature have and why exactly shouldn’t we rely too much on fingerprint security to protect our precious data.

Among the Android phones, Oppo Find X is the first phone to miss the fingerprint scanner in favor of a 3D face unlock feature but still, now that we know the reality of these so-called secure sensors, we would prefer the pin and pattern lock over it any day.
