I am thinking of getting a ZX2 my 64Gb F887 is creaking at the seams, not enough space for a HiRes and lossless CD library that I can listen to whilest travelling, I also use apps as well when travelling. I did consider the ZX100 but the small screen, no touchscreen and basic non-Android OS are dealbreakers for me. Anyhow, my questions are:

The ZX2 currently runs Android 4.2, are there plans to provide an upgrade path to a newer version of android or a new ZX2 with a newer Android version on it?

Once a microSD card is installed, is it included in the library database scan so that the entire music library can be accessed from the Walkman as one library or do you have to switch cards to assess the contents of the SD card?

Sorry if the questions seem a bit basic, but I have no experience of using SD cards as extra storage.
