I first saw it was heading my way last week and, sure enough, last night, Vodafone pushed Android Donut onto my HTC Magic.
I knew pretty much what to expect in terms of headline features, thanks to this video:
but there's a couple of other things that have changed that I really like.
First off, it seems that screen orientation changes are now much faster. Before, when I changed the orientation of the phone from portrait to landscape (or back) it would take a couple of seconds to sort itself now, now it seems to be a fraction of a second — almost to the point of feeling like an instant change.
Another change, again a speed thing, is that the camera feels much more responsive, and quicker to start up too (although I think the startup time as something to do with the above change). This is a good thing from my point of view given that I use the phone as the camera that populates my photoblog.
The new search facility is really nice in that, now, I don't need to bother with the search gadget on the home screen any more. Until now I had it on the middle part of the home screen taking up a fair amount of space (see right) but, with 1.6, the search tool comes up when you press the hardware search button so there's no need to use the gadget any more. That means I get four "cells" back on home. That's come in very handy.
So far I've only run into one problem after the 1.6 install. It seems that Google Search by Voice is now broken. Any time I try and run it I get a "force close" dialog (I know I'm not the only one too because there are plenty of comments in the Android Market reporting the same problem). That's kind of a shame because the new search facility searches contacts, amongst other things, so it would seem like the two together will work as a voice dial (in fact the video above suggests this too). Doubtless a new version of Search by Voice will turn up in the Android Market real soon.
