Nokia 7.2 and Nokia 6.2 might have similar hardware specs concerning the processing power, which is one of the most important specs that distinguish devices. While that might be cool for some, their externals should differ. It would be nice if Audi Q7 would look like Volvo XC90, but that is not the case and some buy Audi and other Volvo because those cars define their owners differently.
According to the product listings for the official clear and flip case for Nokia 6.2 and 7.2, those devices might share the body shape, dimensions and looks. Nokia CC-162/172 or the clear case and Nokia CP-162/172B or flip cover case should be compatible with both Nokia 6.2 and 7.2.
The price of the clear case should be €12.99, while the flip cover case will be pricier at €19.99. Well, this is good because in case you own both 6.2 and 7.2, you can buy one clear case and one flip cover case and change them between the phones.
Oh boy, it will be interesting to see if the front will differ now when we know that the back and the sides are the same at Nokia 6.2 and 7.2.
