In 2021, the user loyalty of various mobile phone brands is released, there is no doubt that Apple is the highest, more than 70% of Apple users will continue to choose Apple when changing machines, after all, iOS is Apple's biggest advantage, the system experience is indeed better than most Android, for many users, it may be difficult to get used to Android, game application data and Android are not compatible, naturally unwilling to try brands other than Apple.
As for the Android side, OPPO is relatively high, more than 40% of OPPO users will still choose OPPO when changing machines, I think it is because OPPO's product strength has been continuously improved in recent years, and many products launched in 2021 are worth buying, and another reason is after-sales. OPPO's after-sales service is definitely a relatively good job among mobile phone manufacturers, not only more after-sales stores (basically can be found around), the service is also quite intimate, such as two-way free shipping, 1 hour quick repair, etc., everyone who has been there knows how good the experience is.
