KPraveenKrishnakumar as usual, Google Pixel phones will be the first to get Android 15 and that’s officially scheduled for October 15th. From that date onwards we can expect other OEMs like Nothing to release their updates. I guess November will be when we can expect Nothing OS 3.0 with Android 15.
Don’t be so anxious about it. It’s better to get the update later but have it throughly tested and bugfree. No Android phone on the market has received the official and final version of Android 15 yet.
