LG G2 and G3 Lollipop update removed some features.

Hello,

So I updated my LG G2 and G3 to Lollipop and I noticed some features are now not working. The android service menu at *#*#4636#*#* now says this app is not supported on this device, it worked in Kitkat though. Also the menu where you can switch LTE Bands has been messed with and I can no longer force my phone to 4G HSPA+. This move has messed with the Modem's on the G2 and G3 and what's happening is my G2's modem will connect to LTE only now, try and call over LTE but VOLTE is not enabled in Portland, OR yet so the call just drops.

I asked LG and they said AT&T may have disabled those features and so Please AT&T, reenable those menus to make my G2 not drop calls anymore and let me switch back to HSPA+ as thats the best network in my area.
