Unknown app icon in iPhone I was organising my app screen on my iPhone SE. I move the apps around till I am satisfied. Once I was done, I got this app icon (red circled on the screenshot) on my main screen.

It doesn't open, if I touch it for long, the other apps start to wiggle in their place, but this doesn't respond at all.

What is this and How do I get rid of it?
Restarting your phone may resolve the issue.
