Meet Samsung's Completely Original Voice Control: Suri
Just because two things look alike doesn't mean the second thing is a copy of the first. Sometimes, there might be essentially only one way for something to work. That said, it might be in your best interest to envision at least a slightly different way of doing something. If for no other reason to prevent posts like this.
Jim Dalrymple posts a link to Samsung’s implementation of their voice control feature. Samsung has been widely criticized, and justifiably so, for copying Apple. The trend continues here. The least they could do would be to slightly change the voice, the way the UI pops into the screen or the shape of the elements, but no.
Apple first gave voice control a personality and interface with the introduction of Siri. It's been widely popular and is pretty well known. If Samsung wants to immunize itself from continued legal action and ridicule, they need to step up their game.
