Has anybody figured out a way to disable 4G on the Spectrum 2 and just use 3G? In the past, when I had the Motorola Droid 4, I did this by using the app "LTE OnOff". All it is, is a shortcut to the submenu "Testing > Phone Info" under the hidden menu (which you used to be able to access by dialing *#*#4636#*#* on older phones). But whenever I try it on the Spectrum 2, it looks like it opens then menu, but then I get the Popup error message "Note: This application does not work on this device," and it closes. I've tried other apps like the old "Phone Info" app, and "Hidden Menus", but they all basically try to lead you to the same place (Testing > Phone Info), and you get the same error message. Very strange. It's like this menu is disabled on this phone. I've also tried going into the phone settings under "Settings > More... > Mobile Networks > System Select > Network Mode", but there's only an option for "LTE/CDMA" (4G/3G). There's no option for "CDMA Only" (3G only). Any ideas? Thanks so much in advance!
