Who I have the same questioned this topic

I just recently upgraded to iPhone XR bc I had to upgrade and didn’t want to be stuck with intentionally obsolete technology and have been Beyond disappointed. The  Phone drops calls, does t matter if I’m in the or house in the car.  I get less signal bars when I’m right next to my router vs being. Out somewhere.  What is the deal with this phone!  I’m really regretting that I got it.  And seriously looking at getting and 8 instead of the garbage. Has Apple come up a with fix for this?  If not - why not
