not going to swear to it but most samsungs "antennas" are located in the bottom of the phone.. nowadays many different makers are placing them there.. wish i had worked on one yet so i would be positive. hope this helps
For health safety, most Samsung phones have the antenna installed near the bottom. When you are talking to someone via call, the lower part is situated far away from the brain, thus reducing the possibility of brain tissue injury. Also you will see that when you have any part of your body in contact with the antenna, the quality of the signal is lowered. This feature is called Specific Absorbtion Rate(SAR). The lower the value, higher is the safety. Hope this helps.
