Three things that can reduce the quality of pictures taken by your smartphone.

1. Dirt accumulation and dust: dirt and dust settle on your camera lens creating a hazy layer in it which affects the picture quality. To rectify this, gently wipe the lens of your camera with a microfiber cloth.

2. Settings misconfiguration: making wrong changes to your camera settings can affect the quality of output of your camera. To correct this, reset your camera settings to default settings.

3. Hardware damage: physical damage to your camera lens can have a great effect on the clarity and sharpness of your pictures. Seek professional assistance to correct any damages you notice on your lens.
