okay so when i try to get people to send me ringtones or pictures through bluetooth, they can search for new devices and find me, but my phone wont respond. once they find my phone and hit send, it says waiting for lg gr500 for a long time and my phone never gets an alert about the file theyre trying to send. i think my phone is the problem because they can find me but my phone is never given an alert saying that someone is trying to bluetooth something to me. what should i do and how do i fix it?
