Google unveiled a lot of cool new Pixel camera features at last week's event. Some of them, such as astrophotography mode, will come on older Pixel devices. But two will obviously remain exceptional for the brand new Pixel 4 and 4 XL: dual exposure controls that let you adjust highlights and shadows right from your viewfinder, and Live HDR +, which gives you a live view of what your photo will look like with Google's applied HDR processing.
Google has confirmed that these features are Exclusive Pixels 4 in response to customer tweet (via 9to5Google ):
Hi Mahfooz, Dual Exposure Controls and Live HDR + Require Live HDR + low-level capabilities in hardware that is only available on Pixel 4, so they won't be available on older Pixel devices.

It seems possible the "low level of hardware" that Google aims to include the new Pixel Neural Core with Pixel 4. We have asked Google for more information and will update this article with everything the company shares.
This week the Pixel 4 goes to stores and suppliers and it's a pretty good Android phone. But if you plan on sticking to Pixel 3 or 3A, you will still get some of the new software capabilities introduced last week, according to this handy list compiled by 9to5Google such as astrophotography and live caption mode.
