How can I fix

@faizanshah like my esteemed colleague @jmehnert already pointed out, you are not telling us what issues your camera lens has. That information would be good for us to have, so we can actually try and help you with that.

For now all we can offer is the teardown for your camera Samsung WB2xx Teardown which does include the lens etc. This should put you into a position, where you can actually wok on your camera and fix whatever issue you may have with the lens. Be aware, replacement parts for the lens may not be easy to come by. You may need to rely on 3D printing or you may need to replace the lens.
