I've had a Samsung Mesmerize on US Cellular for around three weeks now and I love it so far but I just recently started having this problem. I added someone to my contacts, just her phone number no picture or anything and she's not linked to Facebook or Gmail. sometimes when I text her it will work fine. when it's working fine, her whole number will show up at the top of the conversation like this <xxx-xxx-xxxx> as it does with my conversations with anyone else. but just for this one contact and nobody else yet, it will randomly decide to delete the area code from the conversation even though it still shows up in her contact profile. so now in the conversation it's only showing <xxx-xxxx> and it will not let me reply to her when it is like this. the only fix is to delete the conversation, then delete the contact and re-create it. just deleting one or the other will not work. has anyone else had this problem? she's someone I talk to the most frequently so this is a gigantic pain in the ass. any and all help is greatly appreciated. thanks!
