The Amazing In-Glass Fingerprint Sensors Android 101: Everything you need to know!

In-glass fingerprint sensor android! Okay, so most of you must have, at some point in time in the year 2019, seen someone unlocking a phone with their fingerprint through the glass in the display which is pretty dope. That’s like a glimpse into the future of smartphones so for all knocking our phones lately for the last couple years we’ve gotten used to fingerprint readers.

Fingerprint Sensor Android : The Touch ID

Touch ID in fingerprint sensors became that standard and now pretty much every phone that comes out has somewhere on it this fingerprint sensor for unlocking it but, lately, they’ve gotten shoved to like the back of the phone or the sides or just off of the front entirely to accommodate these full-screen phones. The bezel is even in the infinity display now. People love the idea of shrinking bezels and it wouldn’t be wrong to predict that future smartphones will be completely bezel.

Fingerprint Sensor: But…

However, that does, of course, come with a couple sacrifices one of which being where do we move the fingerprint reader you can put it on the back like we’ve seen a lot, you could put it in the power button on the sides there’s a couple of possibilities you can even go the Apple route and totally remove it iPhone 10, of course, has no fingerprint reader and they’ve moved over to facial recognition or face ID.

Synoptic has been hard at work on their own solution and that’s what you just saw working; it’s called clear ID but whatever the name doesn’t really matter what matters is it’s a fingerprint reader underneath the display glass so the sensor itself is called the FS 9500 it’s made by Synaptics and it’s being shown in the VIVO phone called the X20 Plus UD it’s a pretty weird name but it’s on sale.

It’s the first phone that has this fingerprint sensor in it so, it does work in the exact same way that all these previous fingerprint readers have in the past. So, you enroll your fingerprint in the software just like any other fingerprint reader you can do more than one finger if you want and then you’ll notice you won’t be able to scan your finger until a little indicator light turns on, and this is how you know it’s ready to scan and where to put your finger.

Moreover, this is literally an optical sensor; a CMOS sensor the same type you’d find in a camera or in the smartphone camera itself. In order for it to work, firstly, it has to be an OLED display meaning that it’ll only be found in phones with OLED screens.

Secondly, it has to be shining a light on your fingerprint for it to reflect back under the glass and read it. So, when you put your finger on that indicator which is basically a helper for guiding your finger to the right place, you see a light shine for a second; a sort of a pulse that’s long enough for it to read the reflection of your fingerprint on that fingerprint sensor.

What if?

All of that is pretty impressive and it usually brings a couple of main questions to us. Number one: does it affect the performance of the screen in any way? The answer is no, it does not. Number two: can you see it in the display at all; if you tilt it to the right angle can you see the sensor?

The answer is yes. if you look hard enough and while the screen is off at the right angle with just the right amount of light you can see the little rectangular sensor under the display but it’s definitely so subtle that you wouldn’t notice it if you weren’t looking for it and of course once you turn the display on or light up any pixels around it even at the lowest brightness it’s completely invisible so, the in-glass fingerprint sensor is definitely really promising!
