EDIT: I understand what you're implying now, but when I captured this similar screen I was not out of airplane mode. I was driving though an area where traffic was moving 5 mph during rush hour.. I went out of engineering mode.. made a call to see if I could.. went back into engineering where the status had not changed.. there was a "bad value" reading for maybe 5 mins - kept toggling to check...then it simply went to no reading ( it had nothing there ) for several mins.,.If this was a sign of searching I'd think It would go away quick;y and if it didn't - then I wouldnt be able to make a call.... but I had tested this by making a call then again went back to engineering from that after endiing the call..
I thought one of the advantages of e/csfb was the ability to use both LTE and make calls on a CDMA network at the same time if implemented by carrier? I know some are eager for 1x800, but if you're in an area where call quality is mostly superb like where i am - then you're not looking for eagerly for a solution. Id think in a year when voLTE rolls out it would matter even less. Plus wi-fi calling ....
Is my thinking way off?
