Tasteful is not the first word that comes to mind when a company uses a public donation campaign to promote its product, but we’ll let this fly and focus on the message. It all boils down to a bucket of ice water pouring down on the Galaxy S5, and Samsung’s S Voice assistant throwing a punch at the iPhone 5s, HTC One (M8), and Lumia 930. The voice challenges the three phones to take the challenge, knowing they are not protected as well from the elements. The Galaxy S5, on the other hand, takes pride in being IP67 certified, meaning that it's protected from dust and from immersion in water of up to 3 feet deep, for up to 30 minutes.
But in a case of the pot calling the kettle black, Samsung falls victim to its own forgery. Notice how the time in the notification area of the S5 says 2:50pm, while the clock in the middle of the S5 screen reads 2:16pm. This obvious faking of the whole ice bucket challenge turns Samsung hard efforts to mock others at itself.
