Hi, my screen is broken, but I want to make sure my phone is NOT before I spend any money on this. Yesterday, when I broke it, and up until earlier today, I could tell my home screen was being displayed, but it was upside down. The phone also made the usual startup noises and the screen would still rotate. I was using it in my car earlier to make calls while paired to my car so I didn't need a screen. Out of nowhere, the device unpaired and the screen is no longer readable. When I restart it, it no longer makes any of the startup noises. Does this mean my phone is actually broken, or is it still just a screen thing?
