I've been scratching my head with this one for close to a year now. About a year ago my OnePlus Nord CE3 (Android 14, now Android 15) suddenly stopped recognizing the mic on any Bluetooth devices -- even when a device is connected, it stubbornly uses the mic on the phone itself, never the one on the device. I've tried this with two pairs of TWS earphones and a Bluetooth speaker, all running either Bluetooth v5.2 or v5.3. All three of these devices work perfectly when connected to my Windows laptop. Help? This used to work, I can't for the life of me figure why it stopped.

OnePlus Nord CE3 updated to Android 15 yesterday and the UI is...horrible? It's plagued by scaling issues everywhere, widgets are way too huge on the home screen, even messing around in developer settings doesn't fix it. Suggestions?
