With the new Android 6.0 Update Samsung added on some of their devices the possibility to condense system elements and reduce them, this functionality normally is hidden, but thanks to this application you can access it!
*being a hidden fuction, samsung may remove it in future updates, the application actually works on Samsung Galaxy s6 / s6 edge / s6 edge+ / note5 / s7 / s7 edge, future models may or may not be compatible. if you are sure your device has this functionality but my app tells you that you haven't, email me and i'll try to fix it*
