Roland Quandt on Twitter shared a bunch of official-looking renders on Twitter of what he says to be the Nokia G21.

The photos reveal the device in dark brown, dark green, and light green color options and a textured back. In addition, it shows that the G21 will ditch the circular camera module for a more traditional rectangular module. This will house a triple camera setup which is believed to have a 50MP main camera.
Meanwhile, the front of the device looks to have a waterdrop notch up top for the front camera and a bezel at the bottom.
Based on its Geekbench listing, the Nokia G21 will have a Unisoc T606 chipset at the helm coupled with at least 4GB RAM and 128GB storage.
