Galaxy labs added new future for see why phone get heated and which app causing it. I habe download it and seen its results. Its accurately showing it. Below is a post found on xda devlloper site which is in reference from Android police.
Galaxy Labs is also adding a module called Thermal Guardian, which is designed to keep your phone from overheating. Android Police says the module includes a thermal threshold slider that you can adjust when your phone starts to throttle performance.
“Dragging the slider to the far left, the phone informed me that it would start throttling 2 degrees before it usually would,” Android Police said. “Inversely, dragging it to the right will raise that threshold by 2 degrees. All of my devices get toasty during lengthy Duo calls, so I may try the cooler setting and see how things go.”
