Very rarely on Auto - they never seem to focus how I want them to! haha!
I do like P - have my settings that work most of the time locked in and that's like my "auto" but I do manual, Aperture and Shutter priority as well.
I use my cell phone a LOT, especially for my POTD, but its always a bit depressing the lack of quality compared to my DSLR, even for having a 'decent' camera on the phone! But the fact that its almost always with me, makes it my go-to for POTD, I should just get in the habit of carrying one of my point and shoots tho, the quality is so much better!
