Ever since the GB update, I've gone to bed only to wake up to my phone completely disconnected from the network.... no voice.. no data. The only way to restore the connection is to turn the phone off and restart. I've recently turned the power saving options from "Nighttime Saver" to "Performance Mode" to see if this is the issue. Anyone offer any help? For what it's worth, I had to replace about 5 Samsung Fascinates in order to get this phone, so returning this device seems like it's not an option.
