From flashing
LED alerts to scrolling shortcuts, your iPhone has capabilities you may
not have found. We shine the light on some great tips.
You've
likely experienced the frustration that occurs when your iPhone can't
decide which way is up. As you change sitting positions or lie down, it
switches back and forth from portrait to landscape, regardless of
whether you want it to stay in one place.
Stop this pesky screen rotation by first double-clicking the home
button, which will display a list of recently opened apps. Swipe the
list from left to right. This will reveal a set of music controls and a
gray square with a circular arrow on the left. Tap that gray square and
you'll see a message on the bottom that says "Portrait Orientation
Locked." Your screen will no longer flip. Note that the screen cannot be
locked into landscape mode, only portrait.
