Samsung Galaxy S 6 Important Information Manual page 22

Caution! Some applications or prolonged
usage may increase device
temperature. Prolonged skin
contact with a device that is
hot to the touch may produce
skin discomfort or redness,
or low-temperature burns.
If the device feels hot to the
touch, discontinue use and
close all applications or turn
off the device until it cools.
Always ensure that the device
has adequate ventilation and
air flow. Covering the device
with bedding, your body, thick
clothing or any other materials
that significantly affect air flow
may affect the performance of
the phone and poses a possible
risk of fire or explosion, which
could lead to serious bodily
injuries or damage to property.
