In fact, Nothing had already confirmed that Android 13 would not come to its Phone (1) this year. Apparently the tide has turned now. While there won’t be a full, stable Android 13 update for the Nothing Phone (1), the first beta will be out before the end of 2022.
Nothing already tests Android 13 in a closed beta, now the open beta should come sometime in mid-December. If you own a Nothing Phone (1) and want to test the beta build, you can register on this website.
As the text on the site explains, feedback given on the beta build will be used to improve Nothing OS until the official launch of the Android 13 update. However, as with any unfinished software, expect bugs, crashes, and other issues. It is therefore advisable to back up your own data before installing the beta.
Nothing, on the other hand, does not reveal when the stable Android 13 update will come. But since we are only just before the first open beta, the new firmware will definitely not be available this year.
