Yes I did mean "no".
Remember the question is about applying the first law of robotics. "A robot may not injure a human being or, through inaction, allow a human being to come to harm." Your example may show "intelligence" or "conscious" just as plants and animals do but not to the level needed to follow or to act in a way to carry out the first law of robotics.
Cell phones would need to understand that they are a phone and what circumstances are happening right now and how they can affect the outcome. Lets take an example that could be challenged by what the first law says. You make a call the cell phone knows that the conversation you are having is making you or the other person upset (but we will just with our end of the conversation in my making a point although the cell phone would also have to worry about the other person also). Should the phone interfere with the call. It can tell that the conversation is heating up and curse words are involved, it can tell from sensors that your blood pressure is rising, skin sweat is analized, and voice analysis confirms all of this. The phone then taps into your medical history and sees that you have had hart attacks in the past.
Now again what can the cell phone do? Cut the call your on? Call medical services because it beleives your are about to have a medical event? Let it play out and then see if you have a medical event because of the call? Take past calls that you have had (and any on the current call's subject) in the past and not had issues even though they were heated arguments and then figure out a percent based on what you are talking about and how hard that is on your conciousness? So, again, the question is? What can and should the phone do? Terminate the call? Break in with it's own thoughts on the conversation to try to get the heated argument calmed down? Access medical services and put them on standby incase you have a medical event because of the call?
As you can see cell phones are in no way ready to do this type of "thinking or reasoning ability" because they don't have that kind of "conciousness"
