I think this phone is not as good as android phones.But for medium level users it is excellent.It has the features that we need mostly: -( good battery backup, call system, good camera, important social media's.) .It is worth for money in samsung brand and useful for avg user. I used both os( android and tizen) , functions are similar almost. All basic apps like whatsapp, wechat, facebook, sharit are available and it has quick access facility which takes you to site of e-commerce, banking, sports and news. In my view, it is really average smart phone user. Hope samsung will develop its Tizen to beat market monopoly android.
