My qualcomm chip (of samsung galexy core) heat up too much.

nishant singh since you have an IC that heats up immediately, it does sound like you have a shortcircuit somewhere on the board. Not sure which qualcomm chip you are referring to so it will help if you post some good clear images of your circuitboard. That way we can see what you see. Use this guide Bilder zu einer vorhandenen Frage hinzufügen for that. You also need to tell us what you have tried so far to repair this and what happened to it. A bad battery could be a partial cause for this since your IC may be part of the charging circuit etc.
