Keep on mind that htis happens when you mount the device as a sd card because the device can not access the files when connected as Mass Storage... This may be your situation...
Thanks Wildman, for your input.
TBoltOwner, I would like to ask if the contacts are connected to your Google account? Please go to Menu, Settings, Accounts & Sync, and Google. You should then be given options to check. You should check at least "Contacts" and "Gmail."
Add the ringtone through your contact list, click edit and change the ringtone to what you want. Adding it through your contacts once it is synced with your Google account seems to correct it.
Please post back with your findings. Thanks very much!
I did exactly what you said and my phone still plays a ringtone I have set for my girlfriend for anyone that calls but at random when she calls I get the default. It all happens randomly. This seems like a GB error as my phone was fine until the last OTA update.
I'm having the same issues. Works some of the time but randomly goes to default tone. Doing a soft reset (pulling battery) resets it, but now have done reset almost once a day.
I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
i tried this and it does not work. any additional help for now would help.
i had a droid x and loved it. i was given a thunderbolt as a gift.
random ringtones drive me nuts. the htc settings and phone are crazy.
