Or how about Nokia just fix the system. It seems to be pretty broken, and there are non-stop complaints about delayed/missing updates on this forum. Either that, or their update delivery infrastructure is grossly inadequate, and the insane delays are due to them dribbling the updates out to balance load.
I shouldn't have to screw around updating manually. It's inconvenient, and I've read reports of manual updating permanently breaking automatic delivery.
One of Nokia's main selling points for this generation of phones was update service, and it never said anything about having to manually update.
I updated mine to Oreo last month by swapping my sim for an O2 one from my EE sim successfully. and this morning my Nokia 6 (TA 1033) updated itself to the March security patch. I am in the UK. Nick
