Try out phones by Lenovo too. They are good too. I do not know much about the after sales and the software updates that will follow (Samsung does not even update firmware of the lower end phones much). But you can consider phones by Lenovo. Then there is Samsung, if you do not like Lenovo.
Recently switched from an HTC phone (Android) to Nokia (WP8.1) phone and I am loving the clutter free OS. You can give that a try. Not as open as Android, but gets by job done. No more hangs or anything.
Although it is a Chinese phone, I can recommend Tronsmart TS7 Glacier. I own this one since November 2013 and it is plenty fast, with extremely good battery life (you also get two of them in the package!). Has stock Android 4.2.2, no bloatware, no Chinese apps, clean as a whistle. But be prepared to live with this stock OS, since no upgrades are available to 4.3 or 4.4, and I somehow don't think they ever will be.
BTW, it was 150 USD recently... now on discount, 100 USD. A steal.
