[Resolved]  Samsung India — display problem in s8

Address:

Bardhaman, West Bengal

My galaxy S8 display is showing a problem like blinking and low light on 14/12/2018. I was visited the nearest service center on 15/12/2018, they told that it may fall from my hand or damage by me. But there was no dent or any crack on my s8 body or display.
I told them I always keep it on my jeans pocket, before 1 days i saw those problems. They take picture of my phone and send to the higher authority.

On 18/12/2018 they call me and tell that the can not give me any warranty because the display is broken.
I can not understand how the display is broken with out any fault from my side !
also here is not any damage on outside of my phone .
