Samsung — S20+ Handset

My handset S20+ has the claim of being able to dip the handset in upto 4 feet for 30 minutes into water. I used it for 15 seconds in 0.5 feet water and the screen started flickering and the screen is now blacked out. I purchased the handset during March 2020 from Flipkart which had no issues at all prior to this. I would like the refund of the handset as I used the handset as per Samsung's instructions/public claim.
