My story:
Samsung S7 Edge,
color gold, bought last month at T-mobile in the Netherlands.
- within approx. 2/3weeks, the "always on" clock disappeared and randomly colored pixels started blinking on and off, after that the screen turned almost green. I turned the"always on" clock feature off and wanted to monitor the situation a bit longer before I visit the T-mobile store, I was already expecting that it was a begin of something more serious...
- after 3 weeks, in the morning, after charging the phone, weird, mostly purple bar codes started appearing. It occurred a couple of mornings in a row, always after charging. After cooling the phone down the problem disappeared. I also noticed that the black color looked weird in some pictures.
- after 4 weeks, in the morning, the phone screen died. I tried all possible button combinations to restart it, but the screen is partly while, partly black.

I have visited a couple of forums and I see it is common problem ...
The only choice I have is to send it for repair, but it takes 2-3 weeks...
