Sony has started pushing out a new update to its Smartwatch 3. The update carries a build number of M1D63X and bumps the Android Wear version to 1.5.0.3269884. As for what's included, the update clearly brings along Android security patches for the month of September as the security level, post update, shows a date of September 5. Sadly, it's not yet known what else (if at all) the update includes. Via
