Scattered reports of users with both the HTC One Google Play edition and the Galaxy S4 Google Play edition phones seeing an OTA update to Android 4.3 are coming in this evening. We've seen the kernel source for both devices uploaded to the web — a legal requirement before any software is delivered — so we've been expecting the updates.
Users should see the same basic experience that Nexus users have been playing with, plus the few minor additions that Samsung and HTC have made with Boomsound and Flipcover support.
There are bound to be a few bugs, but perhaps the most exciting part of the whole thing is that we've got a good idea what "timely" updates means, at least this time around.
If you've got either of the Google Play edition devices, start hammering that button.
