Lockscreen Delay and Non-responsive to Touch

---

I purchased a Nexus 4 8GB on launch day. The device consistently (multiple times per day) would be non-responsive to my touch on the lock screen when I pushed the power button to do a PIN unlock. I had to cycle the power button to get it to respond to my touch.

I called in an RMA the other night, Google overnighted a new phone to me. The same problem occurs, I haven't installed ANY programs. What are the odds it's hardware and not software?

Does nobody else have this problem???

I can replicate it: Turn the screen off, put five fingers on the screen, at the same time push the power button to bring up the unlock screen. My screen will usually not respond, or it delays a response by a couple seconds. It can take a couple attempts to get it to do it.

The only thing I added was the Google News and Weather widget to the main screen.
