I have the same issue .
Suddenly after a period of two months, on a hot day, I saw the screen of my s10 going from orange or black to white.
I took it to the nearest service center in Athens Greece but they told me that it was broken and asked me for 290 euros for screen replacement because it was not covered by warranty .......
The display had no sign of damage at all, and I did not do anything that could break the display. I explained that on the technician and he responded that the display broke from the inside only, by external press !!!!!!!
The phone was in my loose pocket inside the original Samsung flip cover case and I was walking and did nothing that could press or force the phone. So of course I could not accept this.
I am totally furious with the service center, who from my understanding is a small third party company working for Samsung and is trying to make a profit from repairs and sales.
Ι contacted Samsung support the same day and after 4 days they called me back to say that the display is out of warranty because it is broken without giving me any technical explanations on how this could have happened, or any information about the investigation they performed.
The same polite guy from the call center (located in Romania) that i contacted initially called me without having any more info to share.
I am an electrical engineer myself and my work involves electronics, so i can understand that the technician can absolutely say whatever he or she likes since I cannot open the phone and check myself, but this is not what serious companies should do.
I am really really disappointed by Samsung as a customer. I have bought lots of products, ( smartphones and TV ) but the first time I needed warranty coverage they put the blame on me so so easily ......
This is not the way to stay a Top electronics company in my opinion.
I prefer to buy a much more expensive phone from another company than give them 290 euros for a repair.
Who can say that next time there is a problem it won't be my fault again.
