Randomly will not work. Black screen after boot, phone really hot.

Phone is completely stock. Haven't messed with it at all. My phone died around 5% battery left so I went to put it on charger. Charged it up for like 20 minutes while I watched a movie, and i went to turn it on and it was really hot. It booted up still but whenever it was done booting, the screen just went black. Nothing would work. If i hold power button down, the power down option appears and it works to shut it off. If i shake it, the camera comes up but I cannot take a picture or do anything. Any idea? I also tried to reboot into recovery and couldn't . I dont know if im not pressing the correct buttons so if you know the correct way please let me know.
