Holding your ear to the speaker makes you hear a noise. This bug exists since the beginning of the game. It occurs on different iPhones. The in-game music and the sounds are switched off.
Congrats, you have excellent hearing!
@petri it’s true. Also happens on Android. It’s a low intensity, low frequency continuous sound. I had to max the sound volume on the phone to hear it.
I have the assumption that the battery consumption can be lowered if this problem is resolved
I can hear it (samsung s8)
For me it happens when switching to base view
