How do I fix Daydream in my AT&T Samsung Galaxy S4 recently upgraded to Lollipop 5.01?

[Vital Miranda]

Daydream no longer works since I upgraded my AT&T Samsung Galaxy S4 to Lollipop 5.01. The screen turns off after the screen time out (30 seconds), and no Daydream ever displays. I have done a factory reset twice, and wiped the cache. I have selected many daydream applications and even downloaded some new ones. None of them work with any of the available settings. Nothing I have done works. Does anyone has a suggestion on how to fix this. I have Daydream switched on under the Display in the My Device settings. Any help is greatly appreciated.
