2020 has come to an end, and this year’s flagship model has been released. The most amazing one is the Huawei Mate40 series. So far, everyone is still hard to find. Then there is the iPhone12 series, but the 12 series is on sale from the release. The date is really long, but from the feedback from netizens, it seems that various problems continue. A mobile phone is basically the only one that is popular every day. Is the 12 series really good?
