What is the blue pulsing ring radiating from my home button on my screen?

[AC Question]

I cant click on the ring and it showes up randomly. I cant pinpoint what makes it show up

What device do you have? Also, are you able to take a screen shot of it?

Did you ever find out what it was? I have the same thing.
