Well, some of this was known before, but it was thought tat it's not permanent.
Samsung's highly advertised SUPER AMOLED suffers from burn-in effect.
At first I thought that it was not a big problem since it should disappear after few moments. But this hardware fault is permanent.
You see, since top status bar is almost always on screen it is embedded permanently after a month or two phone usage. Everybody can see this, when you type *#0*# yo'll enter test menu. On the upper part there is red, green and blue square which will turn all screen to respective color when taped on.
Tap on blue since it's most noticeable and look at the upper part of the screen where status bar is, and you can clearly see network status burned in, memory card indicator burned in, time burned in, battery status burned in...
So this effect or fault is here to stay, as I tried some of burn-in screen removal videos and java apps for couple of days and it's the same it doesn't pale off.
