A MediaTek Dimensity 8100 or 8200 is expected to power the phone with a 6.5-inch, FHD+, 120Hz AMOLED display

No information has been released regarding RAM and storage, but the camera department appears to be promising with a 50MP primary camera with OIS, an 8MP secondary camera that is probably an ultrawide, and some sort of low-resolution third camera. There is a 32MP selfie camera on the front.

The Nord CE 3 is rumored to include a 108MP main camera and two 2MP cameras, one for depth perception and the other for macro photography.
