That's not answering the question Personally I find that the way the home screen is built vs. the way it is on apple phones is rather annoying It's not a bad phone, just not necessarily all that great either @all others. The reason OP is asking for this is to make a reasoned evaluation. You can only say so much good, but an unlimited amount of criticism.
First, because most people say it is the best phone.Second, it is the first smartphone run Ice Cream Sandwhich in the world. Third,the hardware configuration on it is great.
I have the Galaxy SII so I don't know how it compares, but I just HATE the keyboard. If you make a mistake (which I find easy to do) the predictions it comes up with are totally random. Makes typing pretty slow going.
Well, if you've a passion for touch screen phones then Galaxy S2 would be best for you. It has a better smooth touch feature as compared to Lumia. Moreover, it has a wider screen which enhances its display feature with better quality.
While comparing to my blackberry curve, all galaxy models are good and having lots of features and mainly application support to the android is higher than other smartphone. But, before buying, just compare it and try to read some reviews online.
The most annoying thing in Galaxy S is its screen - Amoled is too bright, I can't look on it for more than 10 minutes.
