The thing is, the Galaxy S6 is right now the very best Android phone if you mostly care about performance. Its display, camera and proc are unrivaled. Absolutely incredible stuff. Even they managed to implement a good fingerprint reader AND mostly fixed TouchWiz, to the point of making it nice and user friendly at last.
It saddens me to a point, but with so many brilliant phones in the €300 range it looks like Samsung will have to make peace with the idea of the Galaxy S range becoming a halo line instead of its former sales powerhouse.
Back in the day you needed to dole out €600 and over in order to get an Android phone that didn't suck after a year, but that is no longer the case. Samsung needs to wise the fuck up and start fixing its mid range while keeping the Galaxy S as their prestige line.
