It might be bricked. You can power off your phone and try to enter recovery mode( Power, Volume Up and Home ) or download mode( Power, Volume Down and Home )? In recovery mode, you can try wipe data/cache (factory reset) your phone. In download mode, you can flash a new/stock firmware with Odin (it is a little difficult and you should learn enough information before trying). Your S7 edge should recover to normal in either way.
