I have been using samsung galaxy from the beginning but I have also used iphone once but I have got to know that iphone is not a worth to buy.
It also dont have any features as compared to samsung and is very difficult to control and handle. It is also very difficult without bluetooth.
The only thing I like in iphone is its charger, which is very easy to plug in.
If we compare the cameras of iphone and samsung galaxy they are now the same. Galaxy have immensly increased by quality and everything.
