I think the lock icon should be in the circle? I’ll check mine. I think the circle is supposed to be there to emphasize the lock icon, which is being rendered too low on the screen, perhaps.
Other than bubbles or some dirt or something under the screen protector causing a bubble? Nope, nothing I have read here about something like this that isnt related to the screen protector. If you take it off, I bet they go away.
I am having the same issue i removed the screen protector still i see these circles...I am not sure what is the solution. Did you have a screen protector or did you remove one...and did you get this fixed ? if yes how ?
