It looks like Nokia 6.3 is already under the work by HMD global. The latest information came from a factory insider claiming that he had a prototype of the upcoming Nokia 6.3 in his hands, and it has a quad-camera setup at its back. Leakster added that the primary camera will be a 24MP sensor followed by a 12MP ultrawide, 2MP depth, and another 2MP macro sensor.
Some other details that made their way around are that the upcoming Nokia 6.3 will come powered by a more capable Snapdragon 7XX series chipset inside rather than Snapdragon 6XX series usually used in Nokia 6 series smartphones, and Nokia 6.3 will be very compact smartphone design to be used single-handedly.
For authentication, Nokia 6.3 is suggested to come with a traditional rear-mounted fingerprint scanner doubling as a power button.
HMD Global is likely to follow its yearly schedule and launch the Nokia 6.3 in the third quarter of 2020. You can expect Nokia 6.3 to make its way to the store by October.
