Samsung next flagship device Galaxy S5 will be powered by Tizen instead of Android. Samsung is thinking to try it’s own home-grown Tizen mobile OS.
Although there may be no solid backing about this rumor and I do not believe from my heart that Samsung is going to take this huge risk of dumping Android from it’s flagship devices. There are two major reasons, first Samsung already invested so much in Android OS in terms of Smart features, TouchWiz, KNOX etc. and second problem is that Samsung already leading the Android market share using Android.
There are also rumors that Samsung will bring in Optical Image Stabilization camera and Samsung Galaxy S5 will Get Metal Body. But it is very early to predict any of these.
Samsung Galaxy S5 is definitely in pipeline and we will update you as soon as we get more information about the next superphone.
