Tame your text

Q. I upgraded to iOS 8 on my iPhone and now when I'm typing it keeps filling in words for me, and they're rarely the ones I want. How do I stop it?

A. It's called predictive text and it's supposed to learn what words you want and which ones you don't over time. Unfortunately, that does mean suffering with it for a while. If you want to turn it off, go to Settings>>General>>Keyboard and set Predictive to off. Also, if you're running into problems with your iPhone changing words you mistype to completely different words, you can turn off Auto-Correction in the same place. Here are four more common problems with Apple products, such as filled storage, poor battery life and more, and the solutions.

You can drag the "zoom box" around the screen or use pinch and zoom to make it larger or smaller. When you're done, simply triple tap the screen to get things back to normal.

You can pick a critic site you like, such as IMDb or Rotten Tomatoes, then filter the highest-rated movies by type, category or genre. If you're really stuck, it can pull up a random movie for you.
