Your phone goes through a lot each day.
Whether it's kept in a pocket, bag or on a desk, it's surfaces will attract dust and fingerprints - especially the camera lens.
Smartphone camera lenses are very small so even a tiny fleck or mark will be noticeable and might spoil a terrific shot.
So, just before you take that photo, remember to give the lens a wipe with something clean and soft - a shirt sleeve or cloth.
