Motorola RAZR V3c

I know this is an odd question, BUT has anyone noticed a problem with the keypad and/or internal screen overheating after extended periods of time talking on the RAZR?

I have an LG (6100?) that feels like I put my face on a stove top burner if I talk on it too long (ie. more than 15 min. ha), and I would like to avoid another phone like this when I upgrade.

Thanks.
