The Huawei Mate 30 series is to be the next highlight for Huawei in the coming month. However, Huawei will not be able to use Google Services (including Google Maps, YouTube, PlayStore etc) due to licensing issue from the US-China trade war.
However, this doesn’t restrict them to use Android AOSP as their operating system which we can see that it will be featured as their OS. For user who want to use Google apps on Mate 30 series, you will need to side load it just like the phone you bought that comes with China ROM.
Nonetheless, more details will be coming out on 30th September.
