I have my GL hooked up to my computer. I can read the contents of the SD card; but apparently, I'm prevented from doing anything with them. This started with ringtones that worked just fine on my Droid Razr Maxx not working at all on the GL; but not all of them. After getting silence from the phone on trying to assign certain ringtones, I went into My Files to try to play the suspects directly. All I get told is that the player can't play files of this type. Well, it's the same MP3 that played perfectly on the Razr. And now, after altering the ringtone on my computer, I can't copy it to the phone. This makes absolutely no sense at all. I hope this doesn't mean I have to shut off the phone, remove the SD card, copy the file using a card reader, put the card back in the phone, turn it back on, and hope it now works. Anyone run into this? Thanks.
