Lumia 520, all done automatically by night, wake up with a notify "Update installed", all clear by now
That one has always been hit or miss for me. I can get the ring tones to play about 20% of the time. I just have to use a very quick touch on the arrow next to the tone name. Sometimes it plays the ring tone (20% or so), most of the time it just closes the scroll window without changing the ring tone to the one I touched, and the remainder (25% or so) of the times it changes the ring tone to the selected tone. Annoying, but not a total show stopper.Successful though slightly sluggish .63 installation on both a 950XL and a 930. I had .36 on both phones already. Except for the persistent ringtone problem (neither phone will play sample ringtones in the available-tones list in personalization>sound>ringtones, and never has in any version of W10M) everything is fine. It was already fine for me in .36, so I don't have any new happiness to report. I have not noticed any new problems, which is always a good result after an OS upgrade.
