I just bought a Nokia 8 TA-1012 (sim free) on the understanding from several review sites that Android O was now available for this phone in the UK. I've applied the various security patches but there is no Android O upgrade. When will this be available in the UK?
I've received an email from Nokia support asking for IMEI number so they can send me a manual update. I'll let you know how that works out.
I suspect you are right about that, I've just received another email from Nokia support telling me that I'll get the Android O update when I get it and they have closed the call.
