The Nokia N151DL has a circular camera bump, which is the design that HMD Global uses for most of its smartphones right now. This one is probably entry-level since we only see once camera, no fingerprint reader and a pretty chunky bottom bezel (opposite another notch).
Evan Blass has provided images of four unidentified Nokia devices. While we don’t know much about them – not even their names, just their model numbers – they do suggest a shift in design aesthetic. Let’s look at the N150DL and N1530DL first. They have their camera bump at the upper left, a rounded rectangle that is visually split into two parts, indicating that they are definitely related devices. These are most likely mid-range gadgets because to the notch. The fingerprint reader on the side suggests an LCD, and there’s a 3.5 mm headphone jack on top. We couldn’t make out the label on the triple camera, unfortunately.
Finally, the N152DL is most likely a C-series phone, i.e. an Android Go Edition device. Its design looks very similar to the C1 or C01 Plus, which are a few years behind current trends (the C-series aims to be as affordable as possible, so it’s not vain). There’s no word on when these four Nokias will go official, we expect to see more detailed leaks before then.
