Camera locking up and crashing

Today I had multiple camera crashes where starting the camera would cause it to lock up, phone would do a very quick reboot, I would get back in, and camera would crash again. It has been intermittent. Device started getting warm too. Now it seems to be alright. Opening camera on cover screen also crashed and made the cover screen zoomed in permanently. Restarts and cache partition wipes not helping. Issues have been reported to Samsung.
