Nokia 7.3 launch date is yet to be revealed, but the phone is expected to be announced later this year
Furthermore, Nokia 7.3 is also said to feature an improved selfie camera, upgrading from 20MP on the Nokia 7.2 to a 24MP or 32MP lens. Earlier reports claim that HMD Global is testing two Nokia 7.3 prototypes — one with 5G that could be powered by the Snapdragon 765G SoC. Since we're still months away for the official announcement, things might take a turn at any point.
Separately, there have been quite a few developments with regards to the Nokia 9.3 PureView leaks. A recent report suggested the handset would still retain the same Penta-camera setup, but without the Light camera technology, and that it will have a big 108MP ultra-wide-angle lens. Other reports suggest a 64MP primary camera sensor with OIS, but unfortunately, details regarding the other two sensors are unknown at the moment. The Nokia 9.3 PureView is tipped to be powered by the Snapdragon 865 SoC and will have 5G connectivity and wireless charging support. For selfies, the smartphone is said to offer a 48MP front-facing camera. These specifications seem a bit over-the-top and the final product may be completely different.
