Hi I have a Samsung Galaxy s2 t 989 for T Mobile. I have noticed something on my screen today. When I look at my phone at particularly black backround and also in total darkness I see some spots and lines. I had those lines for a while now but two spots in the middle of my screen appeared. They are not visible much only in mentioned conditions. It just makes me wonder what caused them. My phone was never dropped in any water. Maybe it is because of keeping my phone screen facing my leg and higher temp. inside the pocket. Any response is greatly appreciated. I have no idea what this could be. Thanks in advance.
