Black Screen after 4.4.2 update on HTC One

[Anthony Chow]

So over night I updated my HTC One, and this morning when I used it and I pressed the home button, the screen went black, but I can still see the notification bar, and the little bar with the dots at the bottom. This happens every time I press the home button, and what I do to get out of it is to double press the home button, which shows my tasks , then I press it again and it goes to my home screen. I use Nova Launcher, and my phone is NOT rooted. This is irritating me, please help.

I fixed it! All I had to do was change the launcher back and fourth.

I have an HTC m8 and today this is happening to me. I press the home key and the screen goes black except for the function keys. If I press the previous apps key i can get the screens to show up but pressing home just gives me a black screen. I only use the stock launcher
