Hi Mike, just curious about something. I have an HTC Sprint M7, and a while back after an OS update, I lost the ability to see the GCI, PCI, and TAC through Signal Check Pro. I'm still unable to see these in SCP, however in the LTE Discovery app, I can see all three of those values. In SCP, it just tells me those values are invalid or missing. Just curious how that app can see them, but SCP can't. Thanks.
