Okay, so a couple of things to note so far in my experience with CM 13 B2...LTE only seems to activate when WiFi is turned off (also to note that even when LTE is indicated, it is not an option in wireless carriers settings... Only 2G or 3G). I tried resetting network settings, but as soon as I make a WiFi connection. LTE reverts to 3G (no LTE indicator). The other issue is that the system randomly will go into a SIM lock. I can unlock it, and then it locks again. The only way I've found to stop it, is to reboot. Lastly, when powered off and charging, the display backlight stays on.
