"Hi, I'm using iPhone SE and I update it to iOS 12. Then I found that when I open the Phone app, it will be frozen. I can neither select or scroll. I have tried restarting my iPhone but it didn’t work. I found on the internet that it may be related to an app called NoMoRobo, but I didn't have it installed. What can I do to deal with it?"
