The Honor 7X will get the final version of Android 8.0 Oreo in May, including the in-house EMUI (Version 8.0) interface.
For some weeks there is now the beta of Android 8.0 for the Honor 7X and the release will take place in May. Do not be surprised now, because Huawei has announced the update for the second quarter and can now comply.
However, the message comes from China, so it is not clear whether it will go directly worldwide in May. However, I do not think that the international rollout will take much longer and I expect that in Q2 as well.
The Honor 7X costs less than $330, an Oreo release is therefore not at all self-evident, but since it came without Oreo, it was to be desired. This would be a criticism eliminated, with Android 8.1 and the EMUI 8.1 course would have been nice. That (and Android 9.0) will probably not happen.
