Oneplus team has released official android pie update for oneplus 6, which is not an android one phone. here I am using nokia 6.1 plus (Android one) device still not received android pie update. please let us know when we will have hands on android pie .
I am not sure HMD global has outrighg stated anything about when the devices will start getting android P. Android p is still in beta for Nokia 7plus which will be one of the first devices to get it. Its on the final stages of its beta before it starts rolling out for that device. You can expect it to come after they have stabilised the OS for most of their devices
