According to rumors, the ultrasonic fingerprint scanner will be used in the Pixel 9 series.

Unquestionably, under-display fingerprint scanners are a handy way to unlock phones, but not all fingerprint scanners are made equal. While flagships from other manufacturers have embraced ultrasonic fingerprint scanning technology, Google Pixel smartphones have up to now depended on optical fingerprint scanning. However, the Google pixel 9 scanners may follow that strategy.

The Pixel 9, Pixel 9 Pro, and Pixel 9 Pro XL will include Qualcomm's 3D Sonic Gen 2 fingerprint reader, which is the same device seen on the Samsung Galaxy S24 Ultra, an unknown source has informed Android Authority in an exclusive report.

What then is the major issue? Since it's slower and more erratic than the fingerprint scanners on other flagship smartphones, Google's fingerprint scanning hasn't exactly been the best for a while. You should anticipate a failed scan if there is any moisture or dirt present; ultrasonic scanners have much less problems with this kind of problem.

The fact that optical scanners need a strong light source to function is another drawback. You will understand precisely what I mean if you have ever tried to unlock your phone in the dark and missed the scanner. It's not a problem if your thumb is covering the eye-searing light emitted by the scan area, but it may be quite painful if you lose your finger in a dark environment.

It's not as important to place your finger exactly since ultrasonic fingerprint scanners can scan a much wider region. In that sense, the suggested sensor isn't the best. Even while the 3D Sonic Max found in phones like as the Iqoo 11 has a far broader scan area than an optical reader, it is still superior.

The next Pixel Fold is the only forthcoming Pixel smartphone that will not be subjected to ultrasonic treatment. That model seems to be sticking with its side-mounted scanning position.

We'll be watching for further information in the run-up to August 13, which is when the next Pixel lineup is anticipated to be shown. For the time being, how about perusing our guide to the top Google Pixel phones to see what the latest Pixel phones have to offer?
