Microphone issues

A lot of games that require you to blow into the microphone won’t work when you get to that point because my iPhone has noise canceling.

Usually a 5, sound issue makes it 1

I love this app, BUT I intentionally keep my volume at 0 when I play frequently. Right now, it will randomly play sound at 100% volume even though my phone is at 0 volume. This bug needs to be fixed.
