hi. I gave my KA1 for guarantee because of sudden battery problem. They decided to replace it with new one. But I realized that there is a slight white on the screen -as I put a link you to see-, while it is on power off mode.

When I open it to read a book, there is no problem -like on the pic-

do you think should I give it again or what is the problem? or shall I just ignore it?
