Contacts app black screen
My Iphone XR has been behaving weirdly lately. The contacts app is just a black screen when I open it and after a while it crashes. Also when I try to facetime someone, it wont load the Facetime as causes my phone to freezes and requires my to reset it. I have also noticed the text messages take a few minutes for thenotifaction to show up on my phone, but the messages go through right away.
iPhone XR, iOS 15
