Errr it is called "beta test" for a reason, all beta versions aren't final and are expected to have bugs in them. That's why the beta test is still ongoing, so Nothing can gather more issue reports - like yours - in order to get the public stable release as issue free as possible. If you want a stable device: Don't participate in beta testing in the future.
You will have to wait until Nothing releases the stable version of OS 4.0. When will this happen? We don't know yet, could be later this month, but could also very well happen next month. On e the stable release of OS 4.0 will be rolled out, you can upgrade to it just as usual, so no worries there.
Please also use the official feedback form to provide a bug report of your issue, just posting here in Nothing Community won't guarantee your issue being noted by developers:
- Open your phone's settings, go to system, go to feedback (at the very bottom), tap the little feedback button on the lower right and fill out the form
This way your observed bugged is logged by customer service and will be handed over to the development team for further investigation.
Hope this helps!
