There are a few different states an iOS device might be in when one wants to capture a memory really fast:
- Power off, with a PIN or password screen
- Power off, no PIN or password, but need to "slide to unlock"
- Power on - on springboard (no app running, looking at app icons)
- Power on - in an app
In earlier versions of iOS one could double click the home button twice from nearly any situation and open the camera. It appears that there is no quick hardware way built in to the latest versions of iOS, though there is a jailbreak way to enable faster hardware access to the camera. I'm not interested in jailbreaking, though, so I'm hoping to catalog the various methods one can get into the camera app quickly.
Any tips for making this faster in non-jailbroken devices (such as specific apps that are faster, or placing the camera app of choice in the bottom app bar on springboard) would also be welcome.
How quickly can we get the camera to snap a picture?
