I have a Galaxy S4 for about a year, I have this problem almost since I bought it, but it appears and reappears, so I let it go.
My Galaxy S4, using WhatsApp Music and the CPU temperature rises to just using these programs 45-50ºC
Using only the poweramp the instrument reaches 65c for no reason.
Using browser is hopeless, the device rises to 50-70 degrees and finally restarts or shuts down.
When I bought the unit in the first week I realized that he was heating a lot, but did not reach this temperature (50-70) normally.
I read in various forums that the normal temperature of the Galaxy S4 units were 35-56c
Recently, I downloaded a few albums of music and some pictures on my phone that day he shot and started this strange behavior, and following the same steps bellow, the problem still persists.
I already own a Galaxy Note and I have witnessed the bug "AndroidMediaScanner".
I did all the steps (exept formatting the MicroSD, I recently formatted to exFAT SD) Until I checked the status of the reading process of media using the Android ADB, there was nothing abnormal ..
Even without the memory card, few files in SD (just applications) the problem still appears.
What do you think? It may be a hardware problem that requires replacement?
It may be the battery?
It may be the ROM • (when the OmegaROM use a series of modules Xposed)
Recently reinstalled the ROM and the problem still persists.
I read in a blog that the DS Battery Saver could be giving conflict with the manager's native battery used in the Galaxy S4, I uninstalled the program, yet the problem persists warming.
Connected to the USB temperature suddenly increases to 65c without any reason or use.
Sorry for the English. I used Google translator.
Maybe i attach prints.
