Jerry asks: I’m having a problem with an app on my iPhone, and I want to let a friend who’s better at this than I am see what I’m seeing on my screen. Is there some way to take a “picture” of my phone’s screen and send it to a friend for help?
On desktop computers, this is a common request, and it’s easy to do. Both Windows and Mac OS X include built-in features to take screen shots. It’s built-in on the iPhone, as well, but there’s no way anyone would guess how to do it.
To take the screen capture on your iPhone, simultaneously press the Home and Sleep/Wake buttons (the oblong button at the top of the phone). You’ll hear a camera shutter sound, and the screen will flash white. You’ll find the new screen capture in your phone’s saved photos—you can email it from the photo roll to your friend, making it easier to describe the problem you’re having with the phone.
If you’re an Android user, if you have Android 4.0 or greater, it’s easy to take a screen capture: Press and hold the Volume Down and Power buttons at the same time. Again, the screen capture will be saved to your Gallery, and you can email the photo to a friend. (If you’re using an earlier version of Android, it’s probably time to upgrade, but in any case, there are apps you can download to help with screen captures.)
