Mine updated without any problems. The APP informed me that there was an update and 20 minutes later it was done. I tried to keep the phone "awake" as much as possible, but it did go to sleep a few times anyhow. That did not interrupt the update process. I have not tried the set with the new update, but I did not have much connection problems lately anyhow, so it shouldn't be that much different for me. I have an Android phone. Update after some use: no difference. Works well most of the times, but I still get regular right side drop outs while walking outside. Sitting in airplanes and trains that never happens. Also seems to happen mostly when I turn my head, i.e. to look at a shop window.
