IPhone – iOS 10 double click home to pay issue iPhone 6s

If you are using iOS 6 (which I am, I can't get iOS 7 on an iPod 4) and the power is on, no matter what you're doing, the easiest way I found was to press the sleep button to put it on standby, press it again to turn it on, find the little camera icon that's next to the "slide to unlock" bar, drag it up to open the camera, and capture your moment.

Of course, this answer is very conditional: it only works if you have iOS 6, the device is either on or on standby, and you do not have a passcode (if you have a passcode, it makes you type it in before you can use the camera). But it works for me all the time, and I think this would work pretty well for others, too.

I understand your frustration, thankfully, it can be done.

Many video apps, like the YouTube app or the iTunes U App allow you to play the content in the background like music, it just takes a certain trick. The way you do it is two ways, depending on if you want to sleep your iPhone or use other apps while you listen:

Exit the App and then double click the home button, and then swipe to the right to reveal the iPod controls, you should see the youtube or iTunes U app in the place of the iPod Music Icon. Hitting play should continue playing the contents audio in the background while you do other things. Opening another music or sound related app may mute or stop the playing but opening up Safari or checking your mail, text messages, etc should not stop anything.

To have it play in the background with your iPhone in standby mode, i.e., like listening to your music while your iPhone is sleeping. Simply lock your iPhone, the sound will stop. Double click the home button and the iPod controls will show up, press the play button and the audio portion of your iTunes U or Youtube app content should keep playing.

I hope that this information helps you out.
