I dont get very good signal in my office already, but I can make calls and text still. When im on an AOSP or CM11 based rom, it all fails. Also when im on AOSP or CM11 it will connect to the network then instantly disconnect and go into roaming mode then repeat this over and over again. I just want to know if this is a known issue or if there is some kind of fix.
It's related to multisim merges from cyanogenmod. Seems to affect Verizon mostly and 3g. As of right now no fix that I'm aware of. LS doesn't have this bug. It helps to allow roaming. As far as signal bars alone don't tell the whole story. The phone usually gets the same signal check it out with an app called advanced signal status. But aosp has always been slower with data handoffs from 3g to 4g or from WiFi to mobile. But not to say you aren't seeing these issues where aosp can't make calls where stock can but for me I can make calls and use data in all the same places. And I live in a low signal area.
