When Apple first came out with the notch on its iPhone X, the company faced very harsh reviews from critics for ditching the fingerprint scanner. But the revolutionary face ID ended up replacing the fingerprint scanner as a must-have feature in all the smartphones launched since then.
We have seen a radical change in the way we unlock our phone, with facial recognition there is no need to adjust your hand for fingerprint or tab on multiplex on your home screen with code without moving any muscle you can easily unlock your phone.
Following Apple’s footsteps, Huawei is working on making the fingerprint scanner more fun to use. A few days back, the company filed a patent to bring full-screen fingerprint reading to its next line up of smartphones.
The patent also mentioned that the users will now be able to respond to text messages without unlocking their phones. How this will work is that the phone will be able to choose a particular area to activate the screen, which will be used and deactivate the rest of the screen space.
Last year, Qualcomm showed off of its 3D Sonic Max tech featuring a larger sensor, so almost half of your screen can be used to unlock your phone. What Huawei has been developing is far more advanced.
How the fingerprint scanner will work?
We currently use your smartphone to secure certain applications by providing individual fingerprint authentication to all the apps. The way we use it now is first unlock the phone; then, we have to open the app and locate the fingerprint scanner and place your finger to unlock that app.
Lots of steps to follow, isn’t it? Huawei’s fullscreen fingerprint display can bring all these to just one or two steps.
Now with the full-screen as a fingerprint scanner, you can just tap on the app and it unlocks. As the display is fully equipped with a fingerprint scanner, there is no need to locate a particular spot, you can press on any icon anywhere on the screen and it works.
This considerably makes it more effortless to use a fingerprint scanner is a way to secure our phone.
What challenges does Huawei face to bring full-screen fingerprint to reality?
The main challenge this technology faces is the cost. Implementation of this kind of technology requires multiple biometric sensors working together synchronously. Huawei, reportedly, has said that they are working on reducing the cost of sensors. This the best way possible to bring this technology to the market as soon as possible.
One of the issues that come with a full-screen fingerprint scanner is power consumption. Multiple sensors mean a lot of power drain from the phone battery. Huawei has been trying to solve this problem using machine learning. So the phone will only provide power to the part of the screen where the finger touches.
It’s fun to talk about a smartphone with a full-screen sensor but not so fun to bring it to reality. Huawei needs to innovate in many different areas to bring this technology to market. Also with all the trade restrictions placed on the USA’s company, this won’t be an easy task.
The company also needs to keep the final price of the smartphone with such technology within bounds. But as we saw with the Samsung Galaxy Fold of how the smartphone struggled since it’s launch. Huawei has a lot of room to learn from Samsung and also apply. If the company manages to avoid all that we might see an innovative smartphone with a premium price tag.
Huawei is now on a path ahead to be more like Apple. In simple words, the company will soon be controlling both hardware and software on its new line of products. Huawei has chosen to do this not by choice, but as Google denied giving them access to the Google services and the app store.
If the company, by any means, can achieve this, then they will achieve what Apple did with its face ID.
There is no definite date from the company, yet we can expect to see a smartphone with this technology by the end of 2021.
