This might well be one of the disadvantages of Android-based DAPs. The OS tends to be fairly outdated from day one and the, probably due to soc limitations, it's infrequent that they get updated. Thus, streaming apps and the like begin malfunctioning or can't work at all. Plus, even if you try to keep all Google bloatware deactivated, somehow the device gets laggy with time. This has been my experience with zx2 and, before that, with z1060. I own wm1a now and I use that at home, but it still enjoy zx2 very much and use it on the go. However, its limitations grown more apparent with time.
