Not sure if this is specific to my phone, or just a general Android thing, but anyway... I like to make my own ringtones. I made a folder on my phone's microSD card, just called "Ringtones", and dragged all the ones I made into it. They all showed up just fine when I browsed through my phone's ringtones to set one. Today, I got a call, but my phone played some generic little ringtone, and I was confused. I went to my ringtone settings, and it was set to one of the default ringtones. I scrolled down the list, and the one I made that I had set was no longer on the list. A handful of other ones were missing, too, but most were intact. When I open Astro File Manager, and navigate to that ringtones folder I made on the card, they're all still on there. So why did they suddenly disappear from my ringtone list on my phone?
