I live in Italy and I used for one year Huawei Nova 2s with all Google apps with Android 8. It worked properly until the update to Android 9 EMUI 9. Now I install Google play services but the phone is instabe and it is not possibile to use all apps based on Google play services which means almost 90% of useful apps. Incidentally I bought the phone from an internatonal reseller. I made the hard reset of the phone and the result is: China continental.
Therefore now the device is not compatibile with Google.
I tried all GMS instsller and the result is that is possible to install apps but thei will not open itself. It seem that are blocked by an invisibile link. Please help me to solve the problem.
