One has to admit it was inevitable-- advances in foldable displays have lead Motorola to bring back the Razr flip-phone, if in the shape of a 2019 Android smartphone featuring 2004 stylings.
The flip-phone format of the 2019 Razr means the device neatly sidesteps the UI issues associated with foldable phones such as the Samsung Galaxy Fold. Essentially, the 2019 Razr is a 6.2-inch smartphone (if with a taller-than-usual OLED display) users can fold into something half the size. The display even folds flat, making it superior to the Galaxy Fold in that aspect. It also includes a small display on the front cover, allowing one to easily check notifications and the like, and yes, holding up on calls is as easy as snapping the device shut.
Having a bitcoin node does mean the phone can mine for cryptocurrency. Instead, it allows the Exodus 1s to hold an entire bitcoin transaction ledger, allowing it to verify and relay cryptocurrency transaction without need for a 3rd party. It is a fairly compute-heavy task demanding connection to a wifi network and, preferably, plugging the phone into the power adapter. It also requires at least 400GB of storage (via microSD card), since the ledger takes around 260GB and grows at a rate of 60GB per year.
Both Pixel 4 and 4 XL share the same internals in the shape of a Qualcomm Snapdragon 855 chipset, 6GB RAM and 64 or 128GB of storage. The display is 5.7-inch in the regular Pixel 4 and 6.3-inch in the XL, and is based on a 90Hz flexible OLED panel capable of 100000:1 contrast, true black and HDR support. It also features what Google dubs "Motion Sense," a radar system able to detect motion and read hand gestures. For example, it can sense when the phone is about to be picked up and prepare face unlock, or automatically turn off the screen when put down.
