Samsung — Defected product - international warranty

Hello,
I purchased the Galaxy S21+ 5G from UAE about a month ago. My reletives over there shipped it to me here in India and omg this phone is fabulous. But within a coupe of days I started noticing some weird distortion coming up from the top speaker. Its noticeable enough to ruin your otherwise perfectly good audio session. I contacted Samsung support with the same issue and they dismissed my plea as if they have nothing to do with it. Their excuse being that my phone is not covered under warranty in India. But hey, this is a manufactural defect and in these restricting times, overseas travel is basicaly impossible. And guess what, a few days ago, I notices that the screen has the green tint issue tpical of high refresh rate display, often indicating the poor quality. I looked it up on the net and concluded that it is a manufactural defect. All in all, these repairs will cost as much as 25% of the phone's price. Samsung must take this into account and help me with a replacement unit. These kinds of issues are really unacceptable from a phone that costs a THOUSAND DOLLARS. It really irritates me, and made me regret my decision of purchasing the phone. Please, please, help me with this. The supposed 'International Warranty' from a brand like Samsung is supposed to cover this. It sucks that I will have to continue to use the phone in this condition for 4 or 5 years.
P.S: I bought the phone from a local dealer in Dubai.
