Many users have reported iPhone volume button not working, which can be due to software issues, incorrect settings, or hardware problems.
Solutions include removing the iPhone case to check for obstruction, restarting the iPhone, checking volume settings, and cleaning volume buttons.
You can change settings to control ringer volume with volume buttons, clean buttons gently to remove dust, and control volume using AssistiveTouch or Control Center as temporary solutions.
