Sometimes the phone jump to 2G (EDGE) for no reason while HSPA and LTE work perfectly.
Here is the solution (and it will stay after power cycle):
Dial *#*#4636#*#*
Phone Information
Scroll down to network mode and choose "LTE/WCDMA"
Reboot the phone immediately.

This method works for me.

Trying to do this on my D855 international G3, on lollipop, but can't get into the phone information .

*#*#4636#*#* works, but when I click on Phone Information, an error is given 'note this application does not work on this device' . I suspect a changed lollipop radio/Rom thing.

Any idea on how to achieve this another way?
