Display flickering after June 2021 Patch

Dear All,

Anyone facing this weird issue after updating to Patch of June 2021 my Galaxy S20+ display started flickering.

Initially it was some waves then whole display turned into white or yellow with flickering.

Did all the tricks setting reset, Hard reset etc. But no luck same issue.

It seems to be a hardware issue, but interestingly when I restart the device. The welcome logo of Samsung Galaxy S20+ looks perfect and other details, then after loading up it again starts flickering. 

Seems some wrong intention with the patch update

Post the recent security update, my S9 plus phone started to flicker and the battery started to heat up.. I consulted samsung service and they are quoting that due to liquid damage this is caused and said it would cost around 15k for screen & battery replacement..

I don't believe it, i have been using the "samsung's clear case" since the day 1 And never there was any liquid spillage over it.. 

my phone was working very well, and since the last security update I am facing this issue.. 

I have lost trust in Samsung's quality Device and updates.. I would not prefer to buy a Samsung device anymore..
