Smartphone camera quality has improved over the past few years. Because the phones have also become thinner and lighter, being able to hold them steady long enough to take the best photo can be a challenge, but some models have ways to get around this.
On Samsung's Galaxy S III, for example, you can use the voice-control feature built into Android to take a photo by saying "Shoot" into the phone. You need to make sure the voice command option is activated by going in to the Android settings to Language and Input and selecting Voice Command for Apps.
Third-party apps in the Google Play store can bring voice control over the camera to other Android phones. Apple's App Store has similar voice-activated camera programs for the iPhone; the Siri personal assistant in iOS 6 can open the camera program by command.
Tapping the shutter button on Apple's camera app may jiggle the phone and cause the photo to blur, but you can hold an iPhone like a regular camera and press the volume button to take the picture in iOS 5 and later. Holding down the iPhone's onscreen shutter button while lining up a shot and then gently lifting your finger off the screen can help stabilize the camera app as well.
