I am using this product samsung galaxy s9 from past 5 months and facing burn-in display problem after alternate months continuously
my phone is in warrenty period so each time when I go to samsung service centre they always reply that its a minor problem and after forcing them they replace the screen i.e.display and battery but in my last time somewhat around in december 2018 when this burn-in display happen again this time they change the battery, display and the motherboard and within 2-4 days this happens again so I do not recommend anyone to buy this so called flagship phone samsung galaxy s9.So instead of buying this flagship phone go for apple.
