I don't know if my phone works
So I just got an iPhone 6 from a friend. It has a broken screen, and from the looks of it, it may have a broken display as well. I have plugged it in to multiple chargers to see if it would show any signs of life. No vibration when I plugged it in, none when I held the power button, and none other than that. I plugged it multiple computers with multiple cords, and they did not recognize that something was plugged in at all. I don't know how to find out if it works so I know if it's worth trying to fix or not.
