As more and more devices transition to EMUI 10, Huawei has hit an important milestone - there are now 1 million devices running the latest version of the company's custom version of Android.
Here's a list of devices that already made the jump to EMUI 10 (note that some of these are Honor phones running Magic UI 3.0).
More devices are being added to this list, for example the nova 5T. The oldest phones on the EMUI 10 update list are the Mate 10 trio, which hails from late 2017.
