Here's when Nothing is finally rolling out Nothing OS 4.0 based on Android 16

"Nothing introduced Nothing OS 4.0 based on Android 16 back in September, and ever since then it's been testing it with open beta builds. The company has now provided an answer. The rollout will start on November 21. And it's not just the rollout - Nothing promises we'll also get a "full announcement" of Nothing OS 4.0 on that day,"

"The company unfortunately hasn't mentioned whether it will roll out Nothing OS 4.0 to all of its supported phones at the same time or one at a time - we assume the latter since every other smartphone maker does it that way. If that's the case, then we wouldn't be surprised at all to see the Nothing Phone (3) be first in line to receive the update - after all, it is the company's highest-end device to date."

Nothing introduced Nothing OS 4.0 based on Android 16 in September and has been offering open beta builds for testing. The stable rollout of Nothing OS 4.0 will begin on November 21 alongside a full announcement that should provide additional details. The rollout schedule for supported phones has not been specified, and a staged release is likely. The Nothing Phone (3) is expected to be among the first to receive the update because it is the highest-end device in the lineup. The update rollout and announcement aim to finalize and expand on the beta period developments.
