Just entering for completion sake, since it just popped up. I am certain that this phone has by now been fixed :-)

@antonramirez you have two power management IC under there, u5000 and U5001. Those are most likely getting hot. U5000 is for the power on circuit and U5001 is part of the rear camera circuit. U5000 and U5001 are both in the rear camera circuitry. I would start off by disconnecting the cameras and see if that makes a difference. you can also check the components for those circuits. Use the Samsung Flowchart for that. To identify the components, use the component layout file and do a search with your PDF reader for the component. i.e. search for C7032 to find its location.

Ultimately you need the full schematics and board layout files in order to determine if it is the PMIC that is short, or is it some component in the circuit that creates a short circuit.
