The Xiaomi 15 supports the microphone anti-misplug design of middle frame integrated channel.
For your reference, here are the details of the microphone anti-misplug design on the Xiaomi 15:
1. The microphone port is intentionally designed to minimize the risk of accidental damage caused by mis-insertion. As the microphone hole is very small and located close to the SIM card eject hole, their similar appearance could lead to errors, especially when trying to eject the SIM card tray;
2. This anti-misplug design can reduce the likelihood of accidentally inserting the SIM ejector pin into the microphone hole and causing potential damage;
3. Although the Xiaomi 15 is featured with the anti-misplug design when you use the SIM card slot, please do not insert the SIM ejector pin into the microphone hole to avoid damaging it.
