Lens flare has been an issue since cameras were invented. It is not possible to remove but can be reduced by carefully composing the photo and avoiding use of zoom. Better results can be obtained using wide angle lens. It really is more about technique as the best camera/ lens will produce these results in the wrong hands.
ok but this isn't general lens flare ,this is strings of light coming from sources such as lamp posts ,there is videos on YouTube pointing this out on night shot comparisons with other phones ,it looks a mess . if I take a general photo of a street with street lights every street light has this long line of light coming from it . I am aware of flare such as a dot that you can position your ***** into the source of light so the dot dissapears etc but this is next level and unacceptable really.
take this as an example ,look at the state of it ,not only do I have a green dot that I would have to position inside the moon to remove I have a street light that looks completely blown and even gone a bit green.
