Android devices have built-in microphones for voice calls and audio recording, but their quality varies by model. Many users seek external microphones for better audio quality, yet most Android apps do not support recording through them. Currently, audio input selection is limited to individual applications, which can be frustrating. Google has allowed developers to implement microphone settings via the MediaRecorder API, resulting in some apps offering input selection options. Android 16 may introduce a system-wide audio input switcher, allowing users to change the audio input device across all applications. This feature is currently in development and was discovered in the Android 15 QPR1 Beta 3 release, though it is not yet functional. The anticipated release of Android 16 is in Q2 of 2025.
