From the perspective of release time, Huawei's Mate10 series is the earliest model, which has been five years ago. According to the query, the Mate10 series was released by Huawei on October 16, 2017, and the first place was in Munich, Germany. In other words, there are still many users in foreign countries using huawei Mate10 models, which is also the key reason why it can get updates.
In addition, the overseas Huawei P20 series also ushered in the EMUI12 upgrade, which is a model released in Paris, France on March 27, 2018, and has many users in the European market. In terms of configuration, both the Mate10 and P20 series are equipped with Kirin 970 chips, so after upgrading EMUI12, you can also get a good fluency.
