Saidah. This maybe the designed faultiness for their factory mobile phone model, and they haven't modify it properly for wide range of model phones jack. But, all kind of plugy in the market also has the same facts. Since they cannot try out for wide range of phone models. This fits all standard 3.5mm ear phone jack. I've try out Samsung, Xiao mi mobile and it fits good and properly. But it still a very nice cutie deco for your phone. Thank you.
