The S5 was IP67 with a removable battery and an SD slot (so don’t listen when people say they removed batteries for the waterproofing).
The S6 had no waterproofing, no removable battery and no SD slot.
The S7 brought back the SD slot and had IP68 water resistance but they never returned the removable battery.
The fact that shrink-wrapped agreements aren’t automatically void worldwide is a fucking abomination. No you shouldn’t get to push a legally binding contract on me after I paid for the product. It’s my property now and if you want to require a license agreement after the sale then I should be able to decline it for a full refund fuck you.
