Want to know difference between these phones

[super michael]

I have the samsung galaxy ace, what is the difference between samsung galaxy ace and Samsung galaxy S2? Is samsung galaxy S2 way better than samsung galaxy ace like graphic, smoothness like using apps without lag, using browser etc? Is the battery life on samsung galaxy S2 way better than samsung galaxy ace?

What is the difference between samsung galaxy S2 and Samsung galaxy S3? The thing that doesn't appeal to me about the samsung galaxy S3 is the size, it could fall out of the pocket more easier since its bigger.

Both are older devices but the main difference is that the S2 is/was one of samsung's high end devices at the time while the ace was a low budget mid, tier device specifically for the European market I believe.

The S3 is by far a better device than either of those 2.
