So I've had my Captivate for a week or so..and something that is super aggravating to me is that when in an app such as maps..if the backlight turns off, or if you press the home key to use another app-like gmail..whatever...-the gps turns off..so when going back to maps the device has to get another sat lock..which is an issue to begin with. Not happy with that...I thought this thing is supposed to multitask?
