After many classes I have developed a smartphone learning curve for seniors with little or not computer experience, who want to learn how to use the smartphones and tablets.
The only shortcut I know to make the iPhone or iPad do what you want NOW! Is SIRI. Either take a SIRI course or buy a book to help start the journey. Otherwise it is a steep start.
At all stages of the curve, I’ve found learners can ask others that use an iOS or android device for help. The iOS devices are almost one to one compatible. Android devices are a bit harder for people to switch from one to another, but a more experienced user can be lots of help.
Learning about everything physical about the device. Buttons, camera, settings
Learning to modify it. (Requires the Apple password on Apple devices.) Getting apps, email, search, Facetime, games
Uses the internet for maps, travel information, finding museums, food and entertainment, YouTube
Does searches and use complicated sites such as public library sites, Amazon, Flickr, Facebook, Skype
For people unfamiliar with a world where information is almost instantly available on the internet, this is a real challenge.
