Hi, can anyone help me

, i have just bought a MotorolaV535 it's the first time i have bought a new phone for a while so still getting used to it.
The problem is the other day whilst sitting in the pub i decided to power bluetooth on and search for devices, now my phone only managed to find one device (Most the time it does'nt find any) while my mate who was sitting right next to me searched on his old sony erricson and found about ten other phones.
Now is there a a simple setting i have to mess with to sort this out or do some phones just differ from others when it comes to bluetooth??
Appreciate any advice
