SellCell has conducted a survey of 5,000 American phone users in early Mar 2021 indicating that Apple iPhone loyalty (willingness to buy the same brand again) is at an all-time high of 91.9% while Android faithfulness is dropping. Samsung users’ loyalty fell from 85.7% in 2019 to 74% in 2021. It only got worse for other brands. (Apple Insider, SellCell)
