Hello, 

I'm not doing every update as soon as they get out and few days ago a updated my phone. There was 2 updates I believe one for may and one for June. 

Since those 2 updates, my front screen is not "waking up". It still works, I know that because for example if I open the main screen then close the phone without locking it the front display works fine. 

But as soon as I lock it, screen go black (normal) . Then when I want to unlock it, I can feel it unlocks (vibrate) but the screen stays black. I have to fully open my fold4 to see something which is pretty annoying.

Of course no fall or any event, every day use as I always did nothing changed except for the update. And the screen does work so I believe it's more a problem of software than hardware. 

Anybody got the same issue? Can I somehow go back to prior update to check out or something?
