In fact, iFixit admits they’re “at a loss as to how Google stuffed the entire system into a tiny featureless rectangle with no moving parts.” If you geek out on this sort of stuff, iFixit also explains how the chip works.

Pixel 4 Soli chip

According to the company, Soli sends out waves of electromagnetic energy that the chip then analyzes when they’re bounced back towards it. Soli looks at things like time delay and frequency shift to try and determine exactly what kind of object it’s interacting with. It then runs that data against a database of gestures created by Google to decide if it needs to trigger an action. The less complicated version is: “TL; DR: magic rectangle knows your every move.”

One other interesting tidbit of information discovered by iFixit is that Samsung’s Display subsidiary manufactured the Pixel 4’sseemingly inscrutable 90 Hz OLED screen panel. Notably, none of Samsung’s current devices include a higher refresh rate screen, though clearly the company has the ability to add the feature. Whether Samsung will integrate the tech into one of its phones next year is a different question.

After taking apart the entire phone, iFixit awarded the Pixel 4 XL a repairability score of four out of 10 (a higher score indicates an easier to repair device). That’s thesame verdictthe company reached with the Pixel 3. The two phones share all the same positives and negatives when it comes to trying to fix them , including screens that are difficult to replace on both devices.
