Help Random black sliding screen after unlock

[sorinu26]

Hello, sometimes after I unlock my N4 a black screen appears which slides immediately to the left and dissapears. It looks like an app in my opinion.

Somebody encountered this?

I was able to take a screenshot with the black screen:

Sorry to say, that screenshot doesn't help a lot...do you have any more info..??

This appears both on my N4 and my N7.

I'm using Android 4.4.2 untouched on both devices. My launcher is Google launcher.

I think an app is causing this because I have this problem on both devices but I can't find which one. Is there a way I can list all my installed apps here?

I've used apps similar to Share Apps in the past to email myself a list of installed apps (with links to the Play Store for each).

When you got to the my apps in the play store, it has recently updated apps. Maybe its one of these apps that are causing the problem. You could try uninstalling one at a time to see if you can find the problem?
