I'm having a strange problem (at least I think it's strange). My phone no longer detects MP3 files. I can see them in the file browser, but when I try to play them, it says "the player does not support this type of file." This is a bit problematic, considering I use MP3s for my alarms. I was late to work yesterday, and I was almost late today. I powered down the phone and reseated the battery, which appeared to have fixed it, but it wasn't working when I woke up this morning. The only thing I've done is plug it in to the USB cable to charge at night. Any ideas? A search turned up a number of similar unanswered posts. Samsung Galaxy S - Spring Epic 4G Froyo 2.2.1 Rooted.
