Well, excellent. You have a couple of options. This may be the easiest.
Set your phone to the timer option, at the top of the camera screen is a clock. click that and hit 10 seconds.
The means when you hit the shutter button, it is going to count down from 10 and take a burst of photos.
Next, you need a tripod. You'll put the phone in this, and then youve got ten seconds to get the candling right for the photos. It may take a little practice to find out how to use your hands, and if you're at all nervous I would practice with an egg not in the incubator first.
Here's the cheapest, easiest DIY tripod that I make for candling photos.
