Hey there.
First of all, I'd like to apologize if this matter has already been discussed around, it's just that I don't even know what to name this thing so couldn't do much with searching.
Can anyone explain to me what is this happening to my iPod touch? And if there's a way to solve it?
Addition: The "blobs" are slightly movable if I pressure a bit. I just want them to disappear.
