Fingerprint is one of the most efficient unlocking methods on a phone: it’s convenient, direct, and secure. However, its location on the mobile has gone through many places and now the proposal is to allow the entire screen to be used to access the cell phone.
Currently, device manufacturers often put the sensor on the side, with the power button, or at the bottom of the panel, which often requires precision for the user to unlock it.
To solve part of that problem, samsung is developing a new technology that will allow people to put their finger anywhere on the screen to read it and access the phone.

Most manufacturers that use fingerprint unlocking on the screen implement optical solutions that take an illuminated image of the fingerprint to then compare it with the previously registered one and determine whether or not it is the user who wants to access.
Ultrasonic sensors that are emitted to create the image of the finger are now being implemented, seeking to expand this range.
Additionally, this new feature will allow the panel to support up to three fingerprints at the same time, giving more options to people to directly enter the mobile just by putting part of their hand.
At the moment the company is not clear when it will implement this system on its mobile devices, although choy He assured that it will be available “soon”. Although Dieter May, CEO of the French startup ISORGspecialized in sensors for smartphones, assured that the company will have this technology ready in 2025, so there is still time to see it on the market.

Hide a tab in incognito mode with fingerprint
Android users have a privacy option that allows them to protect pages opened in incognito mode in Google’s Chrome browser by limiting their access with their fingerprint or main lock screen pin.
This is the process to activate this feature that is not officially available for now, but can be accessed by enabling an option:
1. Open Chrome on the mobile device.
2. Copy and paste this link in the browser: chrome://flags/#incognito-reauthentication-for-android.
3. Select the ‘Avalible’ button.
4. Look for the ‘Enable device reauthenticate for Incognito’ option.
5. Click on the restart button.
At this point the app will close and turn back on automatically. Then the second part must be done to configure the function:
1. Go to Settings > Privacy and security.
2. Activate the option ‘Lock incognito tabs when I quit Chrome’.
3. Finally, you will verify the fingerprint or PIN that is used on the lock screen.
