There may be more camera tricks in store. It's no secret that the Pixel 4 series has two cameras on the back (a standard 12 megapixel shooter and a 16-megapixel telephoto lens), but the sources also speak of working on a DSLR-like one Essay "for the phones. It's not clear if it's just an add-on lens or something more sophisticated.
It is reported that both pixels will have stereo speakers and Google Assistant features that are (at least initially) only available in the range. Other information is relatively well known. The two ran on Snapdragon 855 chips with 6 GB of RAM, had at least 64 GB of space and left the recess of the display for reasons of gesture radar and face recognition sensors behind.
Google may soon confirm the 90 Hz display, assuming it was willing to annoy Pixel 4 features when they expire. If it is real, it further reflects the sharp change in pixel line strategy. As a rule, pixel phones did not have much more than their cameras and software to set them apart from the crowd. A Pixel 4 with a 90 Hz display, secure face recognition and hands-off gestures would be another story. Although you've seen variations of these features before, using all of the features on a single device could make the pixel even more seductive, even if you do not pay much attention to Google's usual software tricks.
