If you’ve lost functionality, you may wish to report this for the devs to see (in addition to troubleshooting a solution with the community here):
To ensure your feedback gets to the correct teams at Nothing, you must share your thoughts and findings in the correct places:
Phone (1) Feedback:
Report directly on your device by visiting: Settings > System > Feedback
Phone (2) Feedback:
For now, use the Google Form found here. (Feedback via Settings App coming soon)
Issues shared via a discussion on nothing.community are unlikely to be seen by the relevant teams in good time. Discussions can still be used to validate/confirm bugs are repeatable, but feedback should still be submitted as requested above.
