If you didn’t already know, you can capture a screenshot of your device. This is either done by pressing and holding the Home key and the Power key simultaneously, or on some newer device, by pressing volume down and the power button.
You can view captured images in the Gallery app. You can also capture screenshots by swiping the edge of your hand to the left or right across the screen, although this will need to be enabled in Settings > Motions & Gestures.
With the screenshot tools enabled, you can capture the current screen and scrollable area. You can also immediately crop and share the captured screenshot. If this feature is not activated, you can do so in Settings > Advanced features > Screenshots.
Once activated, the Smart Capture tools appear along the bottom of the screen in a transparent bar for a few seconds each time you take a screenshot. You need to be fairly quick to choose the tool you want to use, so it is good to know what each does.
On the far left is the icon to open the gallery app directly to see the image you just captured. The first time you use the button, you will usually be asked to set the default app to use to view your captured images.
The next button is Scroll capture. Tap this and the screen will scroll down, a second image will be captured, and then will be stitched to the first, creating one long image. Useful if you want to capture an image of a web page, for example.
Next to that is the drawing option, which brings up a selection of drawing tools, as well as crop handles, save and share buttons. Drag the corners to crop the image down to a smaller size, then tap the save button.
The hash button allows you set tags on your images as you capture them. Tags are used sort your images into categories, allowing you to find sets of images more easily at a later date. Tap the button then type the name of the tag.
The final button opens the Share panel. Your sharing options will vary, depending on the exact apps you have installed and have used for sharing in the past, but will always include Email, Bluetooth, Messages, etc. Just tap the app you want to use.
