4" class flagships?

I really need smaller phones. I've come to the conclusion I really don't care about the PPI wars (not that I've ever cared that much beyond insisting on a 480p display as a bare minimum for a ~4" handset) and value a device that doesn't get in the way far, far more.

Not interested in the Samsung G4M or the HTC OM. Apart from the Sony Z1S, what else should I be on the lookout for? Ideally I'd like something around 120g, 4.3" max (4" preferred) but leading specs elsewhere.
