Being Pixel 4 and Pixel 4 XL launch day, Google has done what it typically does and went ahead and made the first sets of factory image and OTA files available for each. This one is a bit different, though, because there are 3 files and build versions available for each.
As of right now, the Pixel 4 (“flame”) and Pixel 4 XL (“coral”) have Android 10.0.0 builds QD1A.190821.007, QD1A.190821.011, and QD1A.190821.011.C4 ready to be downloaded.
What’s the difference between each? Umm, Google hasn’t said! What I can tell you is that my Pixel 4 review unit (I had a Verizon SIM in the phone) started on build xx.007 and then received an update to build xx.011.C4. For review purposes Google made it clear that they wanted us to be on a .011 build. They made reference to Face Unlock possibly working better on xx.011, but again, I actually received xx.011.C4.
Should we find out the differences, we’ll update this post. Also, don’t be surprised if you pick up an over-the-air update now that the phone is readily available.
You will find each image or OTA file at the links below. For instructions on how to flash a factory image, here you go. For instructions on how to flash an OTA .zip file, here you go. To check for the update, head into Settings>System>Advanced>System update.
