Update: December 11, 2025 (1:38 PM ET): Nothing has responded to Android Authority’s request for clarification. A spokesperson for the company has offered the following statement:
We use a phased rollout for every major software update so we can identify potential optimisations for users, these are often related to third-party apps.
Such optimisations were identified as part of the Nothing Phone (2a) Series and were rolled out on 1 December 2025. The rollout across all devices is progressing as planned and continues gradually.
