Today I dropped my iPhone 5s on the floor, the impact caused a lot of cracks on the screen, the screen itself is just black. At first it was still working, the screen was showing light when pressing the lock and home buttons, and the phone itself was also making sounds each time a message or call were received, and I was even able to make calls myself and play music through Siri. A few hours later, the phone turned off, I guess because it was out of battery. But, when I tried charging it, it didn't activate (at least i dont think so, because it didn't vibrate or make any sound). I tried resetting it, which didn't have any effect. When I plugged it into the computer, it instantly recognized it, which means that there is nothing wrong with the charger nor with the charger jack. I know that I will need a screen replacement, but I would like to know if its just the screen that is not working, and if there is any way I am able to activate it again to at least be able to make calls with it.
