Well a breakthrough, sort of but not sure yet.....
I have a NotePro 12.2 and use it with a AirTurn foot pedal to turn my music (basically the NotPro is my music stand - se my previous posts).
I have called Samsung 4 or 5 times over the last few weeks after upgrading to 5.0.2 and loosing all connectivity with my AirTurn.
Today I tried something again and got a different result. After being transferred to a supervisor (I requested as the agent was not going to be able to do any of these things I requested - read on) I asked for Samsung to do one of four things (one of these would make me happy):
1) Let me know when a fix was going to be applied and that it will address my specific device (I was told that they are waiting for Google to fix Android 5.0.2 and could not respond)
OR
2) Replace my device with one that is in the box and still running 4.X.X
OR
3) Have my device reimaged
OR
4) GIVE ME MY MONEY BACK !!!
I reminded them the main reason I purchased this device (the 12.2) was for this purpose (music stand) an due to them rolling our this upgrade they have reduced my substantial purchase to a very good looking/expensive BRICK. I also asked them to look at my profile and see how many Samsung Products I have registered (Key Board for the 12.2, NotePro 10.1, Galaxy S5 Active, DVD/Blue ray player, Rugby Phone, and a Gear Fit).
The entire time I was pleasant (no reason to loose your cool (ever) with a front line help desk person(s) who are all very nice) and did not raise my voice.
They chose to have me return my device and they would reimage it to the previous OS level.
I do not know if this will work. I may very well be in for a very frustrating result but they offered and I took it. I will let ya'll know how it turns out. You can choose to try this or wait for me to let ya know if it will work (my recommendation).
I just sent the device (12.2) off.

BTW - I could not get AN2AN to work but seeing how I have a NotPro 101 as a back up I did not try very hard. My phone is at OS 5.0.2 I would need to use the 10.1 and as long as I have it out and the AirTurn works with it I reminded myself why I have a back up (chose not to give the 10.1 to my son when I got the 12.2) and will use that until something breaks.
