Here is all the information on the rumored design, features and released date of the Pixel 4 series.

Since the original Pixel phones, Google has been consistently using two-tone design on its smartphones.

The patent documents revealed that like the predecessor models, the Pixel 4 duo may feature a single rear camera and a fingerprint scanner on its rear shell.

The Pixel 3 XL has a notched display whereas the upper and lower bezels of the Pixel 3 are quite thick. The patent images had revealed a Pixel phone design with notch-less screen. Hence, it is being reported either the Pixel 4 XL may sport a notch-less display. It I speculated that the Pixel 4 will have a 6-inch display whereas the Pixel 4 XL will be equipped with a 6.5-inch screen. The patent documents also showed that the phone features a USB-C and lacks support for 3.5mm audio jack.

The Pixel 3 and 3 XL have 4 GB of RAM and they come in 64 GB and 128 GB storage choices. Probably, at least one of the Pixel 4 phones may feature 6 GB of RAM. There is no information on whether Google will be selling a 256 GB storage edition of the Pixel 4 or 4 XL. Like most Android flagship phones of 2019, the Pixel 4 duo are likely to be powered by Snapdragon 855 mobile platform by Qualcomm.

Needless to say, the Pixel 4 and Pixel 4 XL phones will be preloaded with Android Q OS. Based on information found through a commit in the Android Open Source Project (AOSP) Gerrit, XDA Developers have claimed that the Pixel 4 series may have dual-SIM functionality.
