Although Huawei was never very fast to update its handsets, it seems that the Mate 10 Pro is already receiving Android 9.0 Pie in Europe. Two months since its release, the latest Android version still struggles to hit the 0.1 percent market share. In other markets, this handset should get the update — which comes with EMUI 9.0 on top — in the coming weeks.

I got the update. And now entering access code is slow as hell. It is so slow that the phone thinks I am going to zoom the screen by triple tap. The phone seems to be slower overall. All access rights given to the apps disappeared, autenthication app for netbanking needed to be reinstalled.... What a mess.
