Just ONE at a time.
Slow and steady.
That’s how we “everyday folks” can cope with all this stuff. :)
When you flip your iPhone or iPad from portrait mode (home button on the bottom) to landscape mode (home button) on the right or the left, usually your screen will change with you. (Some apps don’t allow the switch). If you look at a photo, you’ll get a good idea of the flip. Just twist your device and watch the photo change orientation.
Some people prefer using their device one way or the other. (Personally, I prefer to use my iPad in landscape, and my iPhone in portrait. Why? I have no idea. Just do. :lol: )
If you have NOT updated to iOS 7, then you can find your method(s) of locking the screen in this old blog post: Flipping Your iPad: How to Lock Your Screen in Landscape or in Portrait
For those of us who have updated, or perhaps got a brand new iPhone :), iOS 7 has changed the way to access the screen “lock”.
Here is how to LOCK your screen on your iPad or iPhone in iOS 7:
From ANY screen (even if your phone is locked), swipe UP from the bottom.
This is the new Control Center. (More on this, later…)
Tap on the lock screen button. It will be black, but it will turn white once you turn it “on”.
To “undo”, just tap the button, again. Easy, breezy.
For iPad users: you can also use your mute button to lock the screen by going to Settings > General > Lock Rotation
