I love my G6 and I would hate to judge the V30 by what it felt like in the store with a bulky security device attached to the back of it.
How does it feel in the hand compared to the G6?
VERY slippery. However, I have small hands and was nervous, as well, about going with a large phone. It is very manageable. There probably isn't another one out there this size that feels as good as this. Definitely will be adding a thin case for grip.
