iPhone Xs CarPlay/Bluetooth signal bars not updating
Bumping up again, issue still exists under all versions of iOS 13. I have also tested a second Xs, an Xs Max, and an Xr with the exact same results across multiple carriers. Numerous bug reports have been filed, and logs have been collected at their request with no resolution in sight.

iPhone Xs, noticed that the cellular signal strength on both my Mustang and the wifes Grand Cherokee doesn’t update as I’m driving around.
My typical drive from work includes a couple of spots where signal drops from 4 to 1 bars, and I usually watch for these when getting a new phone to see if fringe area coverage improves. I noticed on this new phone that the signal remains at 4 bars as it is when I leave work until I turn the screen on, as soon as the screen is illuminated the signal updates and shows the current signal. Once the display turns off again, signal no longer updates on the car infotainment display again.
Connected my wifes iPhone 8 today and confirmed signals update as expected on her Jeep while driving around. Disconnected her phone, reconnected my Xs and signal strength no longer updates on the display.
