Man, if Sony keeps this up, it almost won’t be newsworthy anymore. Less than halfway into the month and Sony already has the May 2017 Android security update available for a handful of phones. From XperiaBlog:

 Xperia XZ and Xperia X Performance have seen their build numbers move from 41.2.A.2.199 to version 41.2.A.2.223 in this new software.

While, at the same time, the Xperia X and Xperia X Compact have seen their build numbers move from 34.2.A.2.47 to version 34.2.A.2.69. The Xperia X and X Compact remain on Android 7.0 for now. No other changes have been noted so far. 

Now if Sony would only make an Xperia XZ Compact. What a wonderful phone that could be.
