I must admit I feel a bit of a fraud using my wee camera phone. Although I just discovered a couple of nights ago that you can actually change the 'ISO' setting to 100/200/400, change the 'metering exposure' etc.

I look forward to someone telling me what all that actually
means...

ISO relates to what used to be called the film speed - basically, the higher the ISO the more sensitive to light the 'film' is, so if you're taking a lot of pictures in the dark then you want the 400 setting. The trade-off is that the higher the ISO gets, the "grainier" the picture is, so if you decide to enlarge it you get quite a fuzzy image.
Metering exposure - the camera decides how much light to let in. Most of the time the camera's settings are ok, but if you're taking pictures in the snow or on a bright sandy beach, the light that's reflected off the snow or sand fools the camera into thinking that it's brighter than it is, so it underexposes the picture, and you get greyish snow. So you want to change the exposure settings so that it "overexposes" the picture, that way you get nice bright white snow. Depending on how your phone is set up, the "+" means overexposure, the "-" means underexposure. Underexposure is useful when you're taking a picture of something that's spotlit against a dark background. By setting it to "underexpose" you're making the camera think that it's brighter than it is, but you will end up with a better-exposed picture.
