The only thing that stops it sometimes is shutting down, taking out battery for a second and put battery back in and restarting phone. It is the light right below
the camera eye at the top of the phone on the front.
Usually the light on the phone that flashes red or orange is a warning that something may have occurred with the phone i.e. the battery is bad, the phone is too hot, the phone is dangerously cold. Has anything happened recently?
