Soon after updating the Android version of Galaxy Note 3, to get the latest android KitKat updates, there are issues regarding some third party accessories not working.
After the issue was out Samsung told that third party accessory not functioning has nothing to do with the device's android update.
The company says that if some third party accessory do not work on device, it is not the device's fault as the device is build to work perfect with all its official accessories, which it does very nicely. Users can still use the third party accessory but they may have to deal with the short comings of some of them as they do not work on Galaxy Note 3 with the latest Android KitKat Update.
So what Samsung is essentially saying is that certain functionality are only possible with company's official accessories and this could make other third party accessories to not work properly.
Even though Samsung denies it, it is worth noting that the functionality was actually broken only after implementing the latest Android KitKat updates.
