Flipkart — Poco m2 pro mobile phone damage

We bought a brand new poco m2pro by trying a lot (Flashsale). We put great effort to buy a phone as it is a pandemic period and short of money. After all the hardwork and effort, were so happy when it came.
After unboxing we directed phone to charging after that we saw something like a "display damage" (I don't know what's the exact word for that)
Can you believe that a brand new phone with lot of excitement changed to grief all of sudden.
As we believe flipkart is one of the best trusted and good group we ordered and gave money
Its the responsibility of flipkart to check the products they are selling.
Either need a replacement or compensation.
