LG VX-8350

I've had my VX-8350 for about 8 months. During the past couple of months, its transmission and receiving have deteriorated to where the phone is useless. My old phone, a Motorola V276, although inactivated, shows 4 bars while the 8350 shows none. The phone is fully-charged.

I'll be heading for the Verizon store in a day or two - I was just wondering if others have experienced a similar problem?

Thanks
Ted
