Apparently home screen rotation stops working when set to "zoomed"- which is perfectly fine with me. I never liked home rotation, found it annoying.. However, apps still rotate. (Sorry if this was old news..).
Yeah, all comes down to preference. Sometimes I'll lay down on the couch to browse, and it starts to rotate right when I go to press an icon.. Making me select a different one lol.. Like SMELTN said, wish there was a way to turn it off/on for homescreen.
Another thing I've noticed in "zoomed" mode, (most likely a bug) is that when watching a YouTube video in landscape, and you receive a notification, it flips back to portrait automatically every time for a sec, then flips back to landscape. This is pretty annoying.. But I'm sure will be fixed in a future update.
