Hey, so sometimes my phone can be fine but 3 days ago my phone started acting up, sometimes it happens and sometimes it don't but what is happening is I am unable to change the volume, the button works fine, when I click it the numbers pop up at the top indicating how loud I have it at, but for some reason the volume doesn't change, I could put it all the way done to 0/30 and there will still be sound playing or I could turn it up to 30/30 and the sound would still be the same, I haven't dropped my phone or anything, so I am kinda confused.
