Black screen after upgrading to Android Oreo latest version

I have finished upgrading the OS on Samsung S8 and the McAfee black screen blocks me from accessing any other window on the device. I can't do anything. 

Is anyone facing same problem and is there a resolution for that?

I had the same problem this morning. All I see are a few dashes at the top of the screen and I also get notifications saying McAfee security is trying to use the camera.

Need help!!

I've had the same thing this morning but sorted now!  follow these instuctions and you will be back in business......   Ted

 

  1. Turn the device off.
  2. Press and hold the Power key past the model name screen.
  3. When “SAMSUNG” appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see Safe Mode.
  8. Uninstall apps that are causing a problem, ie. McAfee.
  9. Reboot and then McAfee can be re-installed with no issues.

I've tried this, but it won't let me uninstall McAfee! However, I turned off Face Recognition whilst in safe mode and changed some McAfee permissions - which seemed to do the trick.

Thanks for the info on how to access Safe Mode.  Much appreciated!

You have to remove McAfee as an Administrator first, then uninstall the app..

Please note that I had to permanently remove the app because after turning off my phone it happened again!
