The Sony Xperia Z5, Z4 Tablet, and Z3+ have started getting a new update. Arriving as build number 32.3.A.2.33, the update brings along Android security fixes for the month of March - the security patch level says March 1, 2017. Although there isn't yet an official confirmation on it, the update is also said to fix the audio issues that were introduced with the Nougat update. The Nougat update for these devices was first released back in January this year, but was pulled shortly thereafter due to issues reported by early adopters. The roll out restarted last month. Via
