What is this blue and white shield icon on my lock screen?

[Android Central Question]

When my phone is locked It is a blue circle with a white shield and a blue + in the center. It comes up as “hide whats” and then content hidden.
Does anyone know what this is?

Do you have a notification from a medical application installed on your phone?

 

[jennyh1231]

No, Nothing medical

It seems you have an app, security maybe, and you have a notification from it. You should be able to find it by reading the notification.

I can’t unlock the phone.

If anyone has seen this on their phone let me know what app it’s for

You didn't mention you were unable to unlock your phone. Do you have Lookout installed so you can get to it from a desktop?

 

[jennyh1231]

No lookout. It’s not my phone. Just wondering if anyone recognizes the icon
