Google just announced a face unlock feature for the upcoming Pixel 4, which claims to be just as accurate and fast as the iPhone’s Face ID. There have been hardware and code leaks that suggested this feature was coming to the Pixel 4, but there was also another big hint: Google has been publicly gathering data to improve it.

These features are part of something Google’s calling “Motion Sense”, and it’s powered by the company’s Soli chip. Face unlock has been present in tons of Android phones for years now, but Google’s working to make its version the fastest and safest we’ve ever seen.
To make sure the Pixel 4‘s face unlock works as good as it can, however, Google’s now confirmed that it had to conduct “field research” by going out on the streets and paying people with $5 gift cards to scan their faces. A report about this first surfaced earlier this month, but a Google spokesperson has now confirmed it.
After 18 months have passed, Google will get rid of the face data it collected from these tests. Furthermore, while it still has the face scans, it’s said that they’re “encrypted and access restricted” with no connections to people’s Google account if they have one.
It seems like Motion Sense will be one of the main selling points for the Pixel 4, so it’s not surprising that Google wants to take its development seriously. How all of that research and scanning will pay off, however, remains to be seen.
Conclusion :- Overall performance and functionality is awesome. Phone is in budget with good features.It have many advance features when compared with the previous version of google product. while purchasing on On-Line store we can get many benefits like discount, Exchange, EMI and many more.
