The high-end Android market is about as saturated as it can get, because multiple generations of hardware sales keep showing new high-end options dropping out because high-end users (mostly) just want iOS and buy iPhones.

Most high-end phones for Android don't sell like wild fire. AT&T and Verizon stores (among others) are pretty clear that Android is "cheap" and the iPhone is luxury/high-end.

I don't think Microsoft has an answer for that existing market dynamic here for Android phones. There doesn't seem to be enough of a value proposition that Microsoft might have anymore luck as Android device competing against the iPhone.
