Found that unlike the Galaxy SII (which is still a great phone), S3 does NOT truly support Text Reflow. What I mean by that is if you zoom in on a column of text on a web page, the browser always wraps the text so that you don't have to slide left to right and back to read the column.
For years I've said this is the best feature by far of Android vs. IOS. Now Samsung has gone and for some bizarre reason, killed it. They do have some odd 'Reading' button that simplifies the content for reading and that mode oddly does reflow text. however, for whatever reason, it's only available about 50% of the time.
This behavior seems to flow to some other apps as well that supported this. For example, if you try Dolphin HD which is a very nice browser, on the S2 it reflows but NOTon the S3 so they must share some kind of core rendering engine. From what I read, the HTC One X(or EVO 4g as its now named on Sprint) does wrap text nicely and they are both based on the same version of ICS.
Did a ton of research and found that Opera Mobile is the only browser that does wrap and thus that's what I'm using. I'm guessing they use their own rendering engine. Probably because from what I've read they essentially use the same source code on IOS, Android, Mac & PC so it must rely less on the OS.
i do have to say its a very nice browser and its tab view is nicer than the others I've tried.
