It's been happening for a while now but I've just gotten around to posting this issue. I'm running Cyanogenmod 10.1 on my Galaxy Note 2 but one fine day, it stopped showing me the signal bars. I've even updated my ROM twice but it hasn't resolved the issue.
The phone calls and text messages work just fine but it always shows me that I don't have signal. Here's a screenshot:
Would any of you know why this is happening and how I could resolve this issue? Thank you.
