DhananjayBaraik I struggle to see your point here about ignoring very first customers. As you can see from this graph, up to November 2023, there's been a very regular cadence of updates for both devices, especially Phone (1).

Also worth pointing out that NOS 2.5 Beta has already been communicated to land on Phone (1) very soon.
Regarding simultaneous updates, please try to remember Nothing is still a very small company, and most likely doesn't have the resources that other companies have. Plus there's testing that needs to happen before an update is pushed up to us consumers.
