Lighting is always an important factor. Make sure your subject is well-lit, and pay attention to the angles and strength of the light. The better lit your subject is the clearer your image is likely to be. If possible shoot outside or turn on lights when shooting inside. Taking pictures in bright environments provides a faster shutter speed and more depth of field. Therefore, the more light in your environment, the sharper the image.

Pay attention to the position of the basic source of light. Unless you want your subject to appear as a silhouette. Just make sure that you don’t have a bright light behind your subject while taking a picture.

Avoid low light. It is hardly possible to take a good picture under conditions of bad illumination. Camera phones have difficulty capturing details in low-light environments. If the image on your display seems too dark or too light, try adjusting the brightness level before taking the picture.

More advanced camera phones will come with what is known as a night mode feature, which unsurprisingly, is for taking shots in low light and outside at night. If you've got night mode on your cameraphone, do use it.

Some camera phones also come with a built in flash. This can really lift a shot and add clarity to it, even if you’re shooting outside.
