Apart from android being versatile Samsung has been trying to update itself with it's user friendly UI. Right from Galaxy ACE to Note9. I have been using almost every Model Samsung has launched and without any pause I can say it has pioneered in setting a benchmark for itself in this competitive market. Whether its about speed or security (Knox, Samsung Pass) or Innovation ( Dex, Note series with Stylus) or it may be about (Display with curved Edge and Camera with dual pixel or human eye type technology with dual aperture Samsung has set a Class apart for itself in the mass. No doubt Samsung is still no. 1 in numbers compared to other brands.
