It is worth noting that the update is available only for the users in the Wave 1 markets for now, which includes:
Austria (A1 AT, T-Mobile AT)
Among the above-mentioned regions, 30% are already receiving it, 50% will get it by tomorrow (August 21), and the wave one rollout (100%) should get completed on August 22. The other markets might get it in the Wave 2, which usually starts after two weeks of the completion of Wave 1. However, sometimes the updates can arrive in some regions in between the two waves.
With that, the company is still left with two more phones, Nokia 1.4 and Nokia 5.4, from the supposed-Q2 rollout, let alone the Nokia 6.2, Nokia 7.2, and Nokia 9 PureView.
Anyways, do share with us in the comments section below if you are receiving the update on your Nokia 3.4.
