Hi all. I have a new (to me...it's refurbished from Ting.com) LG Marquee. I am trying to add personalized ringtones to my contacts. I know where to go, and I select the ringtone I want for a contact and then hit OK, but instead of saving it, it goes back to Default. No matter if I try a ringtone I've put on the phone or a default one from the phone itself...and no matter if I use the normal way to do it on the phone or use an app (Rings Extended), it never sticks. Help, please? TIA!
