I have working QCI.
It should be noted that the app works a lot better if you disable DSDS in the phone's secret menu. NSG tends to get confused about which SIM card it should show info on if you have DSDS enabled.
Interestingly, my DSDS was already disabled by default for me.Awesome, thanks!
Any idea why @mightyvenom is only seeing the IMS QCI on the Pixel 6?
Does Network Signal Guru display the QCI?
I test prepaid plans and part of that process...forum.xda-developers.com
I'm totally new to this app having only used it once to check QCI on my HTC 10 so I don't really know how to troubleshoot it.
