Obviously, the most notable aspect of the Chinese-made handset is the distinct lack of official access to Google apps and services. This is the first flagship to be released by Huawei since being blacklisted by the US government, therefore it is the first new release to explicitly come without access to common Google Play Services.
Side-loading these services is likely to be possible but it is unclear just how this will be possible for most non-techie buyers. The Huawei Mate 30 Pro does come EMUI 10, which is based upon the recently released Android 10. Although, as expected, this build does not come with any Google apps.
It will be interesting to see how well this handset will perform outside of China. I have my sincerest doubts.
