Antenna locations
Your device may have internal and external antennas. As
with any radio transmitting device, avoid touching the
antenna area unnecessarily while the antenna is
transmitting or receiving. Contact with such an antenna
affects the communication quality and may cause the
device to operate at a higher power level than otherwise
needed and may reduce the battery life.

The Bluetooth, WLAN, GPS, and FM transmitter antennas
are located in the back cover of your device. If you change
the back cover, check that the new cover includes these
antennas, otherwise these connections stop working.
