Features
The iPhone 4S introduced a new automated voice control system called "Siri". It first operated only on the iPhone 4S.Neues iPhone 4S, by Der Speigel, 05.10.2011 (Translation by Google) It allows the user to give commands to the iPhone, which Siri can execute and respond to. For example, iPhone commands such as "What is the weather going to be like?" will generate a response such as "The weather is to be cloudy and rainy and drop to 54 degrees today". These commands can vary greatly and control almost every section of the phone. The commands given do not have to be specific and can be used with natural language. Siri makes it is much easier and/or possible for people to use device functions while driving, exercising, or when they have their hands full. It also means people with trouble reading, seeing, or typing can access the phone more easily. It was became the last smaller iPhone to run iOS 9.
