My daughter and I both recently got the LG Extravert 2 and have both had the same problem. I was the first to have the problem with not being able to delete messages, but I was able to solve it after turning my phone off and removing the battery for 30 secs. But I can't seem to get my daughters phone to do the same. I've made sure the messages aren't locked (I've even locked them and then unlocked them), I've checked all the settings, I've tried to delete all messages in the inbox, all messages from an individual, and deleting each message one at a time; none of which have actually worked. It always tells me that it has worked, but then it returns to the inbox and all the same messages are there. I don't get any kind of error message, or anything saying it can't complete the action. It's getting really frustrating because this phone doesn't seem to have that much of a memory for storing text messages, and once it's full, wont accept any new messages. Anyone else have this issue or know how to fix it?
