I've been watching this forum for days hoping to get any information on this. I've also been writing to Samsung Support through Facebook. They have repeatedly told me a fix was being worked on and would be soon. However, today this is the reply I got. Please keep in mind that I bought the Logitech keyboard at the time of buying the 12.2 Note Prop and my sister purchased the tablet and keyboard at the same time. The Logitech keyboard was strongly encouraged as the keyboard of choice by the Samsung Employee who sold them to us in Best Buy. Additionally, my Microsoft Bluetooth mouse does not work, nor does another Bluetooth keyboard that I've had for a few years. This is their response today....
The information we have received is in regards to Logitech. We have been advised that support is only guaranteed to KitKat 4.4 at the time the device is released. Therefore, there is no guarantee that future operating systems will be compatible. For more information, you can review this link: (it won't let me put the link here so I removed but it's Logitech product page they linked). It is believed to be a similar issue with the other keyboard and mouse. I apologize for the inconvenience.
