Google is done selling the Pixel 4 and Pixel 4 XL. Both handsets are no longer for sale in Google's US store. A spokesperson for the company confirmed with The Verge that the "Google Store has sold through its inventory and completed sales of Pixel 4 [and] 4 XL." And that buyers in the US can only get it through partners who still have supplies. These two devices will continue to get access to software and security updates for three years from when the device first became available.
It has been less than a year since the Pixel 4 and Pixel 4 XL was unveiled, making this the shortest time for a Pixel phone to be on sale. It also means the company has no flagship handset for purchase at the moment. The Pixel 5 won't be coming out until the fall, while the Pixel 4a is a mid-range handset.
