WIFI Calling Preferences Being Forced to Cellular Preferred

The only select few apps I set to allow location access to is Google Maps cloned along with google play services, isolated in my cloned Island work profile for when needed , then two I set to "allow only while using the app which are both needed for IMS registration to successfully complete at boot: DiagMonAgent and IMS Service. Since IMS registration takes place only once on devices at bootup, if I have wifi left on before rebooting it may trip to Cellular Preferred only once just at this moment depending how fast wifi connects vs completion of IMS registation. So as long as I don't restart with wifi on my issue is now 100% resolved and now completely entirely non-existent, "WiFi Preferred" calling mode is now holding persistently, only now accurately displaying unavailable currently when wifi diminishes before dropping or as changing WiFi to another connection, IMS re-establishes and maintains "WiFi Preferred" option through every transition. The other guy can above can run back to Verizon if so he chooses but either way we ALL live in this Google/Microsoft driven world whom both want to know every last detail of none other than you, good luck getting them to change their ways or to get your new carrier to sell you a device that has neither but works on their network, otherwise mod your own device you personally own how you like the way, we in the free/open-source Linux community, always have. Windows 95 does still function also if you so choose to use it for something or like demonstrating how things USED to work in days of ol, but if you want to use it with today's world of software and hardware both, you won't have much luck.  If you merely buy a device from any standard Cell Phone Carrier you are in fact buying into their whole entire knowledgeably ignorant scheme to hand them hundreds of dollars only because their service is somehow unexplainably "better" than their identical competition with identical devices and consolidated shared Cell towers, sales are not developers are not technicians, continue the endless loop. Open source already fixed the problem, Google and Microsoft never will because it is 100% strictly marketing based and profiting them, if a product doesn't work well or no longer does after being updated to "latest improved software" you'll come shovel out hundreds for another new one to replace a 6 month old new one….right??? There are other forums for those carriers too once you find yourself in the exact same current situation once your new device updates itself. Also good preventative to avoid vendor forced OS updates that some have found their devices booting up to regardless of disabling automatic system updates (vendor/carriers do have the ability to and do force system updates occasionally in waves to all devices reporting not being updated after a set time duration expires pushed through SMS/GMS code in the System Update app) if using Island then freeze (disabled until YOU open it)the update app and only update once you know updates are stable, most vendors wait months after security updates are released before they push them to available for your device to see in the first place so a little extra time on your end to actually verify stability between other actual users will keep this and any other unexpected downgraded updates from disrupting life
