I haven't seen any issues, but the update did go strangely. I was offered it about two weeks ago, said OK, it went into update mode, finished updating, rebooted to the Android animation, then went to the 'home' page. I selected my usual HDMI input, and all seemed normal. I did not check the version.
Then two days ago, it offered the update again. So I said OK, it went through the same procedure, except when it was all done including a reboot, it showed a picture for about 30 seconds and then rebooted again, going through the Android animation more slowly, finally confirming the update had been done (didn't do that the first time), then to the home page. I selected my usual HDMI input, and that was that.
