Android support Exchange, however it supports Mail. calendar and contacts (natively). Tasks cannot be synced by default, without a 3rd party app. Having said that, my HTC One M8 has Tasks sync by default (provided by HTC). I don't know about the Samsung.
Another thing to consider is the quality of the default mail app. At least on the HTC it doesn't render html mails well, especially compared to the iPhone.
Fortunately there are good options on the Google Play Store. I use Nine for Mail (it also syncs contacts and calendars, tasks sync is coming soon).

Both apps work really work and they support Exchange features that the iPhone never had, like Categories!
There is also a more sophisticated option: Touchdown. It has really great features, but the UI is archaic, and it looks like a ten years old app..If you don't mind though, then this is the best Exchange client available:
