screen / display / oled panel issue after update

[drpdas]

I m a Galaxy S9+ used. Recently updated my phone to One UI Version 2, Android Version 10.

All of a sudden (without dropping/or any sort of physical assult) the screen started flickering and the colour of the screen went pinkish yellow. The whole screen went dark after that. I was somehow able to judge the whereabouts of the brightness and turned the brightness to max. Now I am able to only use the phone on max brightness (cause reducing the brightness causes the screen to become dark). Also even on high brightness the colour is highly inaccurate. And it looks worse than a 720p display. 

I rebooted my phone (volume down + power key for 10 seconds) but it did not help. 

I contacted Samsung and they suggested that I have to change the display (which costs a fortune for me). And suggested that i might have dropped the phone. But I m a person who is very minimal and careful user let alone any physical assult to the device. I previously used S7 Edge which I bought from Canada and this S9+ is purchased in Bangladesh... Is the hardware issue because it has been purchased here? I paid a furtune getting this phone. And noone has to suffere unnecessary. After sales customer service is horrible. I had been a faithful customer to Samsung for many years but I feel this is unnecessary harassment. Guess it is time to move on.

bro I would suggest you to change the display or sell the phone

Cost to repair the display is BDT 23000. And apparently the resale value of 2 year old Samsung Fladship phone (bought with BDT 99,999) is BDT 22000. I guess I now own the most expensive paperweight.

Try Factory Resetting Your Phone ,if it's a software bug then it will be fixed.

Sometimes the screen turns like this and I have to turn off and on again.
