    Black crush and massive colour banding on GALAXY note 8(SM-N950F Exynos).

    Hello!
    I am using a SAMSUNG GALAXY NOTE 8 Exynos Version 64 gb SM-N950F running on 1 October security patch.
    'Black Crush' and 'Colour Banding' started in April after March security update as i remember.
    I am waiting for a fix but nothing seems to be fixed.
    To explain Black crush in few words: Area with Black pixel where it should show shadow gradient.
    Colour Banding:
    Gradient colour are not transforming smoothly into another one.

    My phone's screen is ridiculously bad to even look at after this. Because let me get straight i bought this to see beautiful AMOLED screen; not to see this bloched screen.
    Anyone facing this issue please comment below as it will be helpful.
    And please note that a screenshot will not identify this problem as other display's on earth are perfect. So you have to take photo with a camera of your NOTE 8.

    I have attached some photos with links to explain it better. This is happening as well as with gradient wallpapers but i can't get focus even on my crappy G5 plus camera.And looks so much worse in real world.

    Here is a link from a XDA thread to show how bad it looks and what is exactly happening here.The post is by GALAXY s9 user which is exact same problem for my GALAXY NOTE 8 now...Weird!

    Thanks to SAMSUNG Customer Care India for replacing my display BUT the problem still persists. I can't even use this phone on regular basis. I am using my broken G5 Plus. Atleast the screen is not that messed up.
    i don't think now that it's a hardware issue; at least display itself is not faulty. But SAMSUNG did something wrong in update and haven't fixed it till now.
    We can't downgrade to Oreo so it's so much frustrating for me.
    Please SAMSUNG fix this ASAP.

    Hmm.... i know. It's not in your hand to fix this. But i m posting here because if you 'SAMMOBILE' can look into this device issue and report to SAMSUNG may be they will notice, otherwise a lots of forums i made on Samsung cummunity and on XDA may go unnoticed regarding exact same issue. I remeber SAMMOBILE posting S9 black crush report and after a month the issue was fixed on my friend's S9... So please help if you guys can.
