One thing about Apple Products is there are lots of settings. If you don't like the way something works there is a pretty good chance there is a setting that can change it. With Settings there is no right or wrong choice, it is your device and you are in charge and can do what ever you want. Personally, I hate autocorrect on spelling but others love it and that is fine. The article below deals with the Mac which is timely for me because my trusty old Mac died about a month ago and I am trying to break in a new one. Even after a month, I am still fiddling with the settings so this machine will work the way I like it. There is a lot of information in the article below and I will keep my eyes open for something like this that deals with the iPhone. Note of warning, I have experienced that sometimes when Apple does an update, many of the settings get reset to the factory default setting. Just this morning I had to tweak the settings on my Apple TV because they changed the screen saver from my Photos to the Apple Photos. The Apple Photos are interesting but I like to see my Photos on the screen saver.
