The game suddenly play BGM sound volume at max, even though I have set my phone sound volume at 0 and when I open control center, I see the sound volume is 0 as well.
This happens many time with this game only, I don’t find this issue with other app. From my observation is it happens when put game in background for a while and then switch back to game, but not guaranteed, it happens randomly.
PS. I didn’t accidentally pressed volume up button, cuz I play one hand.
