I love my quantum. It's Really sturdy. Ive dropped about a million times and no issues yet. I want a FF camera really bad though.
If you look at this forum, the people with the least complaints are the LG owners. I've never had an LG, but they must be a good phone.
My only complaint is that its bulky. But that is what makes it so "fall resistant" so its a pretty fair tradeoff. It may not look as sleek as the other phones but I find it more practical.
Also there may be less complaints because they're a low seller.
