[Update: Fix out] Samsung will begin patching fingerprint scanner security flaw within 24 hours

Samsung really talked up the ultrasonic fingerprint scanner on the Galaxy S10 when it launched. It was supposed to be faster and more secure than other methods. We knew the first part wasn't true soon after launch, but we only found out how easy it was to fool the sensor a few days ago. Cheap screen protectors could allow any fingerprint to unlock the S10 and Note 10 phones, but Samsung promised a quick update. Samsung has now pushed notifications to phones promising the OTA will start in about 24 hours.

Nokia 9 PureView update addresses fingerprint scanner performance

There's a lot to like about the Nokia 9 PureView: it's got a unique camera setup, its construction feels high-end, and it's generally a solid performer. The in-display fingerprint scanner, though, just doesn't work as well as it should. Or at least it hasn't up until now — Nokia is pushing an update that's meant to address the scanner's poor performance.

Why Samsung using ultrasonic tech for the Galaxy S10's in-screen fingerprint scanner matters

Samsung has just announced its latest super-duper flagship phone, and among the new features it boasts is the world's first commercial ultrasonic fingerprint sensor under a display. We've seen other in-display scanners on phones from the likes of OnePlus and Huawei, but they use optical technology instead. This new ultrasonic method is supposed to be better in more ways than one — let's take a look at why.

The OnePlus 6T's in-display fingerprint sensor becomes faster with every use

Fingerprint sensors mounted under phone screens have finally made it to market, and the OnePlus 6T is one of the first phones with the new tech. In our review, we found that the in-display sensor isn't as fast as previous OnePlus phones' fingerprint sensors have been, though it's still quick enough. However, in a recent blog post, OnePlus explains that the 6T's sensor will actually improve over time.

Fingerprint 'master keys' created with neural network could break into your phone

Working with biometrics is always a balancing act. With passwords, authentication is simple — either it matches or it doesn't. But when that "password" is part of a user's body, whether a face scan, iris match, or just a regular old fingerprint, systems have to anticipate and account for a little bit of wiggle room. After all, you don't want that face scan failing because you got a pimple, or your fingerprint rejected because you touch the sensor at a slightly different angle each time. But now a new attack takes advantage of the flexibility programmed into these systems, generating fake "universal" fingerprints.

OnePlus confirms what we already knew: 6T to have in-display fingerprint reader

The OnePlus 6T was rumored to have an in-display fingerprint sensor ever since the Oppo R17 debuted with one. OnePlus phones are often based on one of the R-series devices and as the timing lined up with our expectations for the 6T, we collectively figured it would get one as well. Last week's alleged leaks of the phone's packaging seemed to corroborate that, and now Cnet has received confirmation from OnePlus (with screenshots) that the 6T will have an in-screen fingerprint reader.

Nokia reportedly working on Snapdragon 845 device with in-display fingerprint sensor

Many of us are perfectly happy with the fingerprint scanner positioned on the back of our phones — where there's plenty of room even as bezels on the front shrink. However, under-display sensors continue to be heralded as the next great innovation in mobile tech. Vivo has shown everyone else what's possible and other OEMs are sure to follow suit, hoping that the wow-factor alone will move consumers to get on board.

It wouldn't be a surprise to hear that any Android manufacturer is working on a device with an in-display sensor, and that's exactly what we're hearing about HMD Global, the maker of Nokia-branded handsets.

On Android P, touching the fingerprint scanner will prevent the phone from going to sleep

You're reading a gripping article or story on your phone and suddenly, the display goes a little dim. You know the 30 seconds or 1 minute display timeout you've set is great for regular use, but for reading stacked pieces of text, it's not nearly enough to get through one screen. So you touch the display a little, maybe swipe up and down, just to keep it from sleeping and you continue reading. With Android P, you can do something else: touch the fingerprint scanner.

Opinion: In-screen fingerprint scanners are cool, but may be too late to matter

Here at CES 2018, I had a chance to look at what some of us probably considered mere fantasy a few short years ago: a fingerprint scanner that can see through a smartphone display. It sounds like something that must be so complex it would be beyond explanation, but really, the basic principles aren't terribly difficult to grasp.

The short of it is this: smartphone screens are light-permeable, because they are porous. The thinner the display, the more light-permeable it probably is, and OLED screens are the thinnest currently being manufactured. By shining a bright enough light through the porous display, a sensor can observe the reflection of your fingerprint against the display components and use that to create a computer-readable image.

DigiLux uses fingerprint scanner swipe gestures to control your display's brightness

Swiping down on the fingerprint scanner to show notifications came as a gesture with the Pixels last year and resulted in a lot of drama before it was enabled for Nexus 5X and 6P phones in Android 7.1.2. With Android Oreo 8.0, the fingerprint scanner gesture API was opened up to developers so they could make their own apps with it.

And today's app is built on that. DigiLux uses the fingerprint swipe gesture to lower or raise your display's brightness. Before you start using it, you will need to allow it to modify system settings and turn on its accessibility service.
