Call quality is making me want to go back to my Droid X. Voices go in and out frequently, and it is not because of who I am calling. I was speaking to my mother on her home phone land line and her voice still went out as if I didn't have reception. When I call my girlfriend, who has a Droid X, her voice sounds muffled and I constantly have to ask her to repeat herself. Not to mention the abysmal signal strength I get in my apartment and when I am in most buildings. It makes calls, web browsing, app downloading and pretty much everything I do on the phone slow.
The only reason I didn't trade it sooner was the screen and how well it performs in the sunlight. That is a MAJOR thing for me because I am always walking to and from classes and then back to my apartment. I like to use the music player and text while I walk, so being able to see the phone's screen in direct sunlight is a necessity for me.
