Even though my phone was still under warranty and I believe this was a warranty issue, Samsung made me pay for a new screen, which cost me £208.
I was not best pleased, but they gave me no choice other than to pay for a new screen. :-(
The phone has been OK since, but I think this is an issue that appears over time.
Samsung blamed me for running the screen too brightly over time?
My screen never bright, I dont like the too much light,
However the issue happened when I was driving and the phone adjust itself to be brightest with full color.
I didnt pay a cent
I had the same problem. My phone was under warranty, so I sent it to be repaired. They fixed the problem. 12 months later the problem came back, but this time I'm out of warranty. So I'm trying to fix it again
