The phone was announced in Cairo, so the specs we see here are probably for the EMEA markets - the list price of €109 might not exactly be 'burner phone' money in some territories - as HMD has done some spec-tinkering for other markets before. On the flip side, there's an extra camera at the back for software-induced bokeh, a dedicated Google Assistant button and, as an Android One device, it's got 2 years of OS upgrades and an extra year of security updates in the wings. On this page, you will find tests, full specs, strengths, and weaknesses of each of the devices. 27 days from 2020 and there's still some sort of argument (cost? excess supply? the Luddite faction?) for not putting in Type-C pins in there. Here we compared two budget smartphones: the 5.71-inch Nokia 4.2 (with Qualcomm Snapdragon 439) that was released on February 25, 2019, against the Nokia 2.3, which is powered by MediaTek Helio A22 and came out 10 months after. That means no capacitive fingerprint sensor - just facial recognition for biometric authentication - and no handy reversible USB-C connector, just a microUSB port on USB 2.0.
The 2.3 hones in on that streamlining, enlarges a couple of aspects, but mostly retains much of the kit from the last go around. For context, the Nokia 2.2 from just this June was a vast improvement from its two predecessors in adopting a larger display and slightly sleeker design.
