I have never owned a smartphone and am looking to buy a new iPhone 6S Plus this week.
Can someone recommend some book titles that would best teach me how to use my new phone? (Am looking to buy titles available on Barnes & Noble's website.)
Really all I care about is basic stuff like how to turn it on, how to access the control panel, sending and receiving text messages, how to lock it, how to surf the internet, and so on.
You turn it on by holding the power button on the right side of the phone. It's the lone button on the right side. Left side has a switch that toggles mute and volume buttons. The volume buttons also function as a shutter button in the camera app.
If your phone ever freezes you can hold the power button and the home button (the circle on the front of the phone with the fingerprint reader in it).
You can access the control panel by swiping up from the bottom of the screen. If you have your keyboard up in the messages app you will have to swipe up a bit slower for it to register. It will take getting used to but it DOES open with the keyboard up in imessage.
You text with the app called Messages. It will either be in the row at the very bottom of the screen or it'll be the very first app at the top left corner of your screen by default. It looks like a speech bubble.
Surfing the internet is done with Safari. White icon with a blue compass inside it.
You lock the phone by hitting the power button or just leaving it alone for a few seconds. Hitting the "power" button doesn't turn it off unless you hold it down. It's technically called a sleep/wake button.
Honestly, it's a really simple phone to get used to. Pretty much everything is very simple to find and use on an iphone to the point that there's not a whole lot to learn from a book that you can't learn by poking around with it for a few minutes. It's a pretty accessible phone.
Also... Screenshots are done with Home + Sleep/Wake button. Hit them together and your screen will flash. It saves them to your pictures.
The 6S will probably have iOS 9 on it. You update by hitting Settings > General > Software Update or just waiting for it to bug you about it.
