The 4G connection available in the US on the Samsung Epic 4G Touch matches that of any other Sprint phone, which is to say the speed is good but not great. We clocked a bandwidth speed of 3Mbps.
That's adequate for most purposes, but not nearly as fast as Verizon or AT&T LTE speeds in the US of about 12Mbps.
The browser is standard issue for Android 2.3.4, without any extra frills. Pages loaded quickly and accurately, with Flash and other moving content, such as the rotating stories at TechRadar.com, displayed normally.
You can quickly zoom in with a two-finger spread or pinch to zoom out. When you do, the screen changes quickly to match the zoom level. Text reflows accurately and looks crisp when you re-format as it should.
Like every other Android 2.3 smartphone, you can bookmark web pages by pressing an easy-to-find bookmark icon to the right of the URL. Bookmarking is fast, but the browser doesn't offer any social networking features - say, sharing something you bookmark on Twitter or Facebook.
