Recently while playing a game (COD Mobile) I noticed that when I connect my headphones (either Bluetooth or wired) the game voice chat uses the phone's mic instead of headphones. There is no setting in the game that let me change this. I also notice that (for example) when I send Whatsapp voice notes It also uses phone's mic. Headphones microphone is only activated during phone calls.
Is there a way to change this? I don't want to use phones mic when playing games but headphones one.
