Samsung — Display white line issue

Address: Behind the Minaxi talkies, near Gajanan Mandir,

Hello Sir, I am from a Samsung family since last 25 years. All the phones in my house come from Samsung. I am using Samsung Galaxy M52 since last 4 years. Now I am seeing a vertical white line in the display of this device.If it faces two major problems which have increased tomorrow and its new display comes for Rs. 9000 then Samsung's new mobile devices are currently available at that price, so my humble request to you is That you give me some discount in the price of the display so that I can replace the display and if we replace the device every 4 years, this does not happen to a normal person, at least for 7 to 8 years we can replace the device properly Or you can remove this white line by updating some software and help us as much as possible. This is my request to you because I cannot spend Rs. 9000. How can a middle class man spend so much money?
