Samsung Galaxy s6 Screen black, glitching and blue light flashing.

[AC Question]

I threw my phone (like a complete overconfident *****) to a friend and it hit my dresser. Since then, my phone has a black screen that occasionally has a quick bar of light flash across it. Looks super glitchy. A blue light is flashing and the phone itself is warm. Did the battery get messed up? What did I do?
