This is verging on, or in fact going past paranoid, but I was reading an ebook using the kindle app in a dark room, and i noticed that when I controlled the brightness of the screen by using the brightness option within the app, there was a pattern that emerged as the brightness went down which seems to border the text. It changes size as the brightness is lowered and raised. Just wondering if this is meant to be like this, because at first i thought it was some sort of border pattern, but the way it changes in size as i decrease the backlight makes it seem like it is a result of 'seeing' the light decrease and increase on the white background of the book 'page' (if that makes any sense). Perhaps somebody could try it in a dark room and see if they see it?
I don't care that it is there as long as it is not abnormal or anything, for example something to do with the BL. Again, sorry for the paranoia
