sorry this did not help me..i have tried it.At some low brightness the colour and screen looks absolutely fine but when i increase it the display looks pale yellowish and pathetic.Suggest something else

ok.But there is a certain colour loss..may be image is not that clear..colours are very dull after the issue..purple seem to be light blue kind of..so u can imagine the difference..

It happned suddenly..phone did not suffer any physical or water damage..how to fix it?

this is the quality of colours now..very dull and low brightness.

last update i did it from the service centre itself.So it was properly done.And it just happened suddnly.My phone did not fall down or there is no physical damage or water issue..How to fix it ???.i will post a display image of it for your reference.
