This is a WTF problem. I have an HTC Desire, bought it last August. When I first got it, it would randomly play some strange song that I have no clue where it is on the device. It sounds like it could be some sort of alert or ringtone. Did it a few times, then it stopped. Didn't think about it as it was not an ongoing issue. However, recently I did a reset and now it's been happening again. There is no rhyme or reason, it's totally random and getting annoying. I had the HTC Hero previously, and never happened with that phone. I am using the same SD card, but I have gone through all my ringtones, alerts, notification sounds, and MP3 files but have no clue what's causing this. Any ideas?
