Can you do a screenshot and show us? If not we can't tell you what's wrong. While in camera, press and hold the power button untill a menu appear. then just take a screenshot.
thanx for the pic. it helps to confirm that it's not on or in the lens. if u look at it closely, these are not dots. they are actualy tear or punctured holes. most likely the sensor, or a layer that's covering the sensor.
sad to say, but i think you need to return your phone to the service centre. no amount of software fix can fix this.
that, i won't know. like yourself, i'm just a consumer.
they will ether replace the camera sensor, the whole motherboard itself+sensor, or the whole phone itself. i guess it depends on which is more cost effective and readily available at that time.
