Actually I don't think she's wrong. After 'living' with the V20 for a couple of weeks, the camera experience is just not consistent, and even less so when you compare it to the likes of the S7 or the Pixel (I've owned the first, not the latter, though).
The first thing I noticed is how 'unfit for cropping' the pictures looked, especially on the Wide Lens camera. And it seems I'm not alone. I didn't, however, experience the shaky video she did.
But yeah, when you market this as a 'content creation' device, it certainly doesn't live up to the marketing hype.
It's not a bad device. I like how fast it is (definitely zippier than an S7), but the camera leaves much to be desired when it's competing against top shooters like Samsung's or Apple's.
