How can you put your fingerprint on the mobile screen without the reader first? Is it possible to have it? Although the answers seem very reasonable, exploring TikTok we encountered these doubts on several occasions.
Some people say it’s possible, others recommend apps that supposedly do it, but is what these videos show true? Today we will reveal whether or not it is possible to enable the fingerprint reader on the screen of your mobile phone, although it is not official. Are you waiting to find out?
False: If your mobile doesn’t have an in-screen fingerprint reader, you can’t set it up
As we mentioned earlier, some users of Tik Tok claim that the mobile screen can be used as a fingerprint reader to unlock even though the sensor is not in the first place. The principle behind this rumor is that all mobile screens will integrate a fingerprint reader because they are touch. So even if your smartphone has an official side or rear fingerprint reader, you can still unlock it with biometrics by placing your fingerprint on the screen.
The fact is that the biometric sensor is only in the place indicated by the manufacturer, so this is completely wrong. this is A completely independent piece to the touch screen coverSo it has nothing to do with her. If your phone manufacturer says the biometric reader is on the side, it won’t be on the screen. If it says it’s on the back, it won’t be on the screen either. And if it says it’s on the screen, it won’t be anywhere else or you can’t move it there, at least not easily.
Why do we make this final explanation? Because it can definitely be done, but only if you have the appropriate technical knowledge in electronics and software. In other words, if you’re a handyman when it comes to these things, you can probably upgrade your phone to install the fingerprint reader somewhere else and reconfigure the software to read the biometric data from there. However, this is something that requires a lot of knowledge. It is dangerous and will void your warranty.. It’s not something anyone can do, a simple app you download from the internet and that’s it.
In fact, we invite you to be very careful about this kind of thing. These types of videos may be a malicious app trying to sneak malware onto your smartphone. Also, you should understand another thing: there are different fingerprint readers for mobile phones and they cannot be installed everywhere.
What kind of fingerprint sensors are there in mobile phones?
Although the central question of this article has already been discussed, it is good to have more information about the types of fingerprint readers used in mobile phones and how each one works. Various technologies have been used over the past few years, but the majority of the market has opted for these options:
Capacitive fingerprint sensors: They were very popular at the time and are still found in many devices. They work similarly to touch screens by detecting the electrical charge on our fingers. The grooves of the foot do not touch the ground, so they do not grip. Contact lines work, so they are captured and stored as a special pattern to help you unlock your phone. Sensors of this type They are used on the back and sidesEven if they are on the physical “home” key, disappearing at some point. They are the most reliable and fastest Physical optical fingerprint reader: They have been used very little in the mobile market because they are very easy to cheat, slow and ineffective. These By taking a photo, they capture the fingerprint in 2D, is stored and used for comparison during opening. Since it’s not a 3D model, your fingerprints aren’t as prominent as other readers, which is actually its main drawback. They go under the screen and only work with OLED panels. In this case They use an ultrasound transmitter and a microphone. The transmitter emits sound from the surface of your finger and the microphone is responsible for recording the frequency, including any irregularities in the fingerprint. The footage is in 3D, so it’s safer. They weren’t that fast at first, but today they’ve improved a lot.
You already know, don’t let yourself be fooled and don’t believe everything you see on social media. And if a friend comes to tell you how to configure the on-screen fingerprint reader even if it’s not there, I’ll be happy to present this article to them.
