Nokia X6-00 - My phone feels warm   In most cases it is normal
for your phone to warm up, for example, when you are using
multiple high-performing apps, listening to music for an
extended time, or when your phone’s charging. The environmental
temperature may also cause your phone to warm up.  Your phone
meets Nokia’s high testing standards for device safety. Nokia
also meets the international standard for safety (IEC 60950-1)
and country-specific requirements.  To avoid getting too warm
and to protect itself, your phone may automatically slow down,
close apps, and, if necessary, switch itself off.
