Part 2 > Q123:
My device is getting hot
Q : When I’m using my Galaxy S4 , I often feel my device is hot to the touch. Is my device faulty?
A :Your device is not faulty.
However Samsung has released an enhanced Software . You can upgrade to the latest Software via the Kies tool
(visit
for further information regarding Kies) or via FOTA
Upgrading the software enhances the device’s performance and will help reduce the operating temperature
via temperature control method implemented by Samsung .
Additionally, when you use applications that require more power or use applications on your device for an extended period of
time, you may feel your device is hot to the touch. This is normal and should not affect your device’s lifespan or performance.
And while charging, the device may heat up. This is the same, and if the battery gets hotter than usual, the charger may stop
charging.(This is also explained in User Manual)
Samsung observes the International Safety Specification. At the same time, Samsung will continue to make our best effort to
optimize the software features for user convenience.

Octa Core CPU ,
does it heat up than Quad Core ?
A : The temperature of Smartphone is not related to type of AP chip.
