I literally just got the Optimus S two days ago. I'm already not recieving calls and when I finally do get those calls the quality is so bad. The other person has a hard time hearing me or/and I can't hear them very well (Like talking to someone in a tunnel). In one case, I was talking to my friend and suddenly the couldn't hear me hardly at all. I had to hang up and begin the phone call all over again. (BTW: I get great signal where I am. Always have full bars) Also, it will suddenly stops loading my apps. For example, I'll pull up Twitter and it just loads and loads. Nothing happens and it says it can't recieve the data. I had to restart my phone again. I haven't had any other trouble except it can be a little choppy and slow, but that's what I already expected really. Any help would be awesome. I wonder if I just got a lemon and need to return it. Thank you!
