Hi I asked about this problem in the Optimus GT540 forum 2 weeks ago and nobody was able to help, so I thought I would try here. Hope you can help. I have an lg optimus gt540 android mobile as stated and when I use the music player that comes with android it lists every track twice on my screen. So if a album has 10 tracks it doubles it up to 20 tracks and it does this for every track. If I play an album I hear a track twice before hearing the next track twice and so on. I have a 16gb SD memory card with plenty of space left on it in the mobile. I have about 80 albums on the memory card. I have checked and there is only 1 of every track on the memory card and not two as the music player is listing. Do you know how I can fix this problem? I installed the avg free version app to see if my mobile has any viruses but my mobile is not powerful enough to run it and it locks up, so I have un-installed it. Thanks if you can help.
