Some cameras come with a built in flash or light - this can really lift a shot and add clarity to it, even if you're shooting outside (in a sense it becomes a fill flash). If your camera doesn't have a flash or light you should avoid shooting into bright lights as you'll end up with subjects that silhouetted.
Get Close to Your Subject.
One of the most common mistakes with camera phone images is that their subjects ends up being a tiny, unrecognized object in the distance. Camera Phone images tend to be small due to low resolution (although this is changing) - so fill up your view finder with your subject to save having to zoom in on the subject in editing it later (which decreases quality even more).
Keep Still.
As with all digital photography, the more steady your camera phone is when taking your shot the clearer your image will be.
This is especially important in low light situations where the camera will select longer shutter speeds to compensate for the lack of light. One trick is to lean your camera phone (or the hand holding it) against a solid object (like a tree, wall, ledge) when taking shots.
Positioning your camera phone right, can set up the lighting and keeping still can make the quality outstanding. That is for camera phone status, who looks going through Instagram and wants to see that blurry photo of a winter morning or a selfie....no one. A helpful tip when taking photos, don't worry about editing until later.
