There is too much stress on the system, hence it cannot cope and malfunctions. Your best bet is to shut down the iPhone and let it rest.[1]Furthermore, your power source may cause this to happen. For example, charging your iPhone via your computer with the lightning cable may not provide sufficient power for your iPhone.
