The last months without any damage or break of the screen it started to turn green at the very beginning and after one point it started to turn to total black. I contacted with the service and they just told me that this not their problem and they cant do anything about it. I've been a samsung user for the last 8 years and i always buy phones of the S series because i think that they totally worth it but after S9 i'm strongly dissatisfied especially with the treatment. I paid 900 euros for this phone and it started to have issues without any damage from my side. If nothing happens i will never buy a samsung device again and of course i will never suggest it to any of the people i know.
