I have an AT&T HTC One. I put the developer rom on my phone because I wanted no carrier bloat, quicker updates etc. I'm having an issue where my signal info isn't accurate at all though. I only have 1 bar at all times, but I don't think that's accurate because my data speeds are very high and it doesn't really match up with what I see in Advanced Signal Status. I tried changing the "sku id" to "7" for AT&T instead of "6" in /system/customize/ACC/default.xml. It changed it to the AT&T icons and stuff up top but my signal stayed only at 2 or 3 bars no matter what, even when I had no coverage. I've also tried installing several different radio versions (including ones that I know worked from my previous rom). I'm not even sure what I'm seeing in my signal apps are correct either... does anybody have any ideas about what could be up here? I attached a file showing my signal status and my bars.
Thanks in advance!
