There has been a lot of talk about the Android operating system, and what will be the upgrade to it. Most Android devices that are newer (less than two years old) have already received their upgrade to Android M (also known as version 6.0 or Marshmallow) already, but eventually, version 7.0 (also known as Nougat or Android N) will also be available. This is the latest news on Android M Version 6.0 Marshmallow and Android Nougat Release Date for Sony Xperia Z5, Z4, Z3, and Z2 on Sprint, AT&T, T-Mobile, US Cellular, and Verizon.
The thing about Sony is that they were slow with getting out the upgrades from Android. If you want to get in on the next version of Marshmallow, then you are probably going to need the Xperia Z5, the Xperia Z5 Compact, the Xperia Z5 Premium, Xperia Z4 Tablet, Xperia Z3, Xperia Z3 Compact, Xperia Z2 Tablet, and the Xperia Z2 which are all seeing the Android 6 Marshmallow upgrade. Unfortunately, it won't be receiving the Xperia Z1 and the Xperia Z1 Compact.
There is some new updates for Sony, as a recent report from IBTimes reveals that the Xperia M4 Aqua and M5 is getting Android 6.0.1 Marshmallow update. There have been reports that it will be coming to the Xperia C5 Ultra and the Xperia C4.
If you are a Sony user of a newer device in the United States, see if you can't get the OTA (Over The Air) download of Android Marshmallow now. Just go into the "Settings" and "System Update" to see if the upgrade is available. The upgrade may not be available depending on your carriers like T-Mobile, Sprint, US Cellular, AT&T, and Verizon. Feel free to leave a comment here saying whether or not you received your Marshmallow on your Sony device, as well as what carriers that you subscribe to.
So what will be the first Sony devices to receive Android N? Chances are, it will be the Sony Xperia X devices first. Given that the newer Android devices receive the upgrade first, it will probably happen in this order: Z5-branded series (Z5 Premium, Z5 Compact, and the simple Z5), then the Z4 tablet, and the Z3 series. Sort of like how the Z1 series won't be getting Marshmallow, it will be unlikely that the Z2 will get Nougat. The Z3 series is pretty popular, so it would not be surprising if Nougat comes there.
