I have a rooted Epic. I was trying to get into and view my system folders and write ringtones to the system media files, as well as notification tones, etc. I found File Expert, a free app in the marketplace, and was successfully able to copy ringtone and notification .mp3 files to the phones system designated files (system/media/audio/"ringtones" or "notifications"). My plan is to not have to worry about keeping these files on my SD Card, especially since my SD Card has an issue with unmounting itself, and my ringtones disappearing. I've missed a few important calls because of this, and it drives me crazy. The problem is, once my files were added into system directory, and I rebooted my phone, the files show up in my system ringtones when I go to change them, but will not play. The ringtones are in .mp3 format, but that was never an issue coming from the SD Card. also, all of the original ringtones (the .oog files) still play perfectly fine. Any idea as to why this is, and what I need to do to get the .mp3's to play as system ringtones? Screenshot of my system file with the ringtones in place.
