do you here the ring in the bluetooth device? in most cases, the phone shouldn't ring if bluetooth is on, hence the term "hands free". if not, then there might be an issue.
could be your phone having an issue. my gf recently replaced an lg g2 due to wifi issues. if you have problems on multiple networks then just take it in.

Be careful in downloading any other emulator than those mentioned above. And make sure to check the files you download
