As was to be expected, smartphone sales dropped significantly in Q2 2020. The question is how manufacturers react in this environment. Changes can be made in the product portfolio, pricing and promotion strategy as well as sales channel strategies.
Samsung suffered most, but I would venture that their wide product range and economies of scale should have allowed them to react better. The article mentions the Note 20 as a possible saviour for Samsung, but I doubt that, even though it is a great product. It is just the wrong price at the wrong time for it make a significant impact.
