After update my Z1 to 4.4.4 deodex FW, in menu for mobile network just disappear option to choose only 2g .
In picture is my current setting. There is LTE/3G/2G option, only 3G and 2G/3G.
During update I dont wipe data. Can be that the problem?? Or is just normaln that you cant have only 2G network on android 4.4.4?
