Since a 4G connection can cause a dramatic drop in battery power, many users of the AT&T Samsung Galaxy Note have been asking about disabling the 4G connection on the device. Unfortunately, you won’t find a setting for turning 4G off within the Android setting menus. You do have a couple of options though.
While there is no option to utilize a plain 3G signal on the AT&T network, you can use a network switching widget such as Widgetsoid to toggle the setting to down to 2G.
Your other option would be to disable the data connection entirely. This can be done by going to Settings > Wireless and network > Mobile networks > uncheck Use packet data.
It’s quite frustrating that the device doesn’t give the user more control. If any of you out there come up with something that works better for you, please share it below in the comments section.
