I just got the phone about a week ago & the volume buttons are unresponsive unless I open my control centre or a few hours after I restart the device. I thought downloading the latest software would fix the problem but to my shock & anger it still isn’t working properly. I’ve attached a video of the process I have to go through in order to increase/decrease the volume on my phone. I understand that this can seem like first world problems but it’s annoying that a brand new device isn’t working properly
