At first glance, the new S6 and S6 Edge appear to be less cluttered, but you'll actually find some 56 applications pre-installed. That's 6 more than the 50 you'll find on the Galaxy Note 4! Between the Google Apps you'll find on every phone (Play Newstand? Come on), Samsung's apps like S Voice and S Health, the new Microsoft apps like OneDrive (intended to soften the blow of no microSD slot), assorted social apps like Whatsapp and Instagram, and carrier apps (6 on T-Mobile), there's a ton of cruft. A Moto G I have hanging around—which runs near stock Android—starts with just 33.
Ugh everything about this, though I'd be remiss if I didn't mention a certain folder on my iPhone overflowing with apps that I don't want and can't delete.
