I just got the S21. While on a call, I tried to reply to a text using the microphone (voice input to text). I got a notification that says “can’t use voice input while on a call.” So it’s prohibited. By default, voice input is controlled by Samsung. I also switched to google for voice input to see if that worked. I don’t get an error message but Google says something to the effect of “I didn’t catch that,” so it doesn’t work either at the moment.
Any workaround for this? Is this an android 11 issue? I could voice text while on a call on a galaxy note 4 (android 6). All these years later and the S21 is incapable of doing this? Frustrating.
