I bought this for my cuff SONY XPERIA Z2 .... and yes .... it does not exist for this brand then adapts .... I find the scratch too small to close the band and suddenly, during intense exertion it opens. My phone is a little too big for the cuff so that the "camera" button is active only. But hey, at the base this armband is not done for the SONY. We must get used to having that thing around your arm and then ..... well it goes alone ..... except that you twist the neck and arms to read the screen !! ! But there is no solution .... except a watch connected !!! Good sport !!
