That was the song of praise, but now follows the thing that in my opinion does not fit.
Here can be found in the description nothing that said battery cover has a very wide black border and in the pictures is not much to see.
With a black or blue Galaxy S4 falls not or hardly noticeable.
But if, like me, has a Galaxy S4 in White Frost I feel that very disturbing !!
Someone else might say that such a thing is getting used to, it bothers me stop.
Otherwise, I am so far satisfied with the battery cover.
