At least there is such an opinion
Nokia smartphones are one of the last mainstays of pure Android, that is, these devices do not have their own graphical shell.
Nokia smartphones may lose one of the main features that make them stand out in the market. They may have their own shell
However, this may change soon. HDM Global, which licenses the Nokia brand, is said to be looking for a designer. In English, the vacancy is called User Experience Designer, but a direct translation into Russian will not give an understanding of the essence. In fact, from the description of the vacancy, it is impossible to say unequivocally that we are talking about the design of the graphical shell, but the source adheres to exactly this opinion.
For example, it cannot be ruled out that HMD simply wants to develop some kind of its own application for its smartphones.
