Samsung is top-tier by Android standards. 4 years of security updates and 3 years of OS upgrades (minimum - some devices, such as the premium models, get more than that).
Better than Google themselves when last I checked, which is shameful.
What would such an assumption have to do with anything? I put my seatbelt on even when I don't intend to get into car crashes.
Arbitration clauses and class-action waivers universally favor the corporation -- in this case Google -- and should not be legal. I'm proud to retain my basic legal rights.
