Pixel 4

Google is expected to announce the successors to last year’s Pixel 3 and Pixel 3 XL devices in October. The Pixel 4 series will feature a slew of upgrades over last year’s models. Google, in fact, has been teasing information around the Pixel 4 for a couple of weeks now. In the newest such teaser, the company has more or less confirmed at least two features that are definitely coming to the Pixel 4; Face Unlock and motion gestures. Before we talk about these features, it would be a good idea to watch Google’s teaser video which we have embedded below.

Google Pixel 4: What to make of the latest video

As seen in the video above, Google has made it amply clear that the Pixel 4 series will support face unlock. However, being a flagship-class device, the face unlock capabilities of the Pixel 4 series would be in line with Apple’s Face ID technology. However, Google’s implementation would be markedly different from that of Apple. Apart from using the Soli sensor to support hand gestures, the Pixel 4 will also feature two IR cameras that will be dedicated for face unlock. Apple, in comparison, used just one IR camera. These cameras will use the flood illuminator to precisely map your facial contours for better face detection. Google is reportedly also building a stereo image of your face using these sensors which would ensure better detection under challenging scenarios like when the phone is placed on a table, and your face is not in direct line of sight to the camera. The aim, it seems, is to make the face unlock feature as fast and secure as existing fingerprint scanning mechanisms. The other major feature that you can expect with the Pixel 4 is its exceptional motion-sensing capabilities thanks to the motion-sensing radar called Soli. While I am still doubtful about the usefulness of having to use a motion-sensing gesture when the screen is just inches away from us, I am willing to wait to see what Google has in store for us. The primary use case, it seems, will be for actions like skipping songs, snoozing alarms, and silence phone calls.

Google Pixel 4: What we know so far

As mentioned at the beginning of this article, this is not the first time that Google has posted a teaser about the Pixel 4. The company had on its social media accounts posted an image of the rear panel of the device a few days ago. We are yet to see an image in which the front portion of the device is clearly visible. The previous generation Pixel devices – especially the Pixel 3 XL – was severely criticized for its huge notch. While we do not know if the notch would make a comeback, it is near certain that the Pixel 4 will have a large bezel area at the top to accommodate all the motion sensing and face unlock the hardware. Apart from this, the handset will be powered wither by the Snapdragon 855 or the newer 855 Plus chipset with at least 6GB of RAM. The Pixel 4 will also run Android Q at launch.
