Yeah, I was camping on the JMT between the half dome trailhead and the clouds rest trailhead on the evening of July 4th.
I swear I heard some big crashing sound that evening, but never located where it might have come from. Of course it would have been on the opposite side of Half Dome from where I was, so wouldn't have been able to see any dust or anything from a fall.
Still can't be sure that it was this, but so far all the news peg the fall as being between July 3rd and 5th when the climbers found their route missing, so you never know.
Didn't even hear about the half dome slab failing until I got home. Despite having cell coverage, most of my time in the Yosemite 'wilderness' I tried to only use it for weather forecast checks.
