Picked up my Epic this morning and love it. Also have an EVO and love it too. But, one issue I am having is my Epic has a much weaker signal than my EVO. It's not just less bars, but it's noticeable in sound quality/loss while talking on the phone. For example, my EVO has 2 bars and a weak signal at my home. The Epic has 0 bars and virtually no signal. Any thoughts on this issue?
