Until the weekend I'd always used a USB stick for my music store in my NX450h and all worked fine but having just bought a new Samsung mobile with oodles of storage I decided to use the phone as the music store. One of the main reasons for doing this was to free up the USB data connector for Android Auto if ever needed.
One difference that became instantly apparent is that the interface presented is slightly different than that when using music sourced from USB. The interface using the USB displayed an A-Z quick list option on the far right of the screen which, although too small and a bit of a pain to touch on, gave me the option of quickly moving to artists\albums\tracks beginning with a certain letter. This option isn't present when music is sourced from the Samsung phone so if I want to choose music from say, ZZ Top, I have to scroll through every artist entry from A to Z. This takes an age.
Has anyone else noticed this? Is it linked to the phone model or is it the same for all phones? Is there a workaround?
