Unknown Microphone access in control center
I updated to iOS 18.3 a few days previously, and it's been running well on my iPhone. However, I noticed something wrong on my home screen. The Microphone was on. When I opened the control center, it said that an unknown app had access to the microphone, but it had done so without my consent. When I checked settings to see if there was an app that had requested access, there was none.
The Issue was resolved after a hard restart, but it still baffles me. This has never happened in the past ten years of using the iPhone.
