2 bugs to report;
1. usb charging port registering charging when off the charger. Couldn't sync with Zune w/o plugging in and restarting. Randomly played the plug-in sound. Poor battery life. Sent to Samsung under warranty, they replaced component, 2 week turn around.
2. touch screen unresponsive and phone wouldn't go into sleep mode, just remained on with either start screen or lock screen displayed. Several button presses on same icon/letter/number to get input. Phone currently at Samsung repair center.
Love this phone, really bummed about the problems but Samsung is covering their stuff, which is good.
