Sony Xperia Z3+ and Z3+ Dual receiving Android 7.0 Nougat update

If you've got either of the two Xperia smartphones, then you should check for a new update with firmware number 32.3.A.0.372. It's the same build that the Xperia Z5 family received recently and it will update the Xperia Z3+ and Z3 Dual to Android 7.0 Nougat.
The Japanese handset maker is now seeding Android 7.0 Nougat to a small percentage of Xperia Z3+ and Z3+ Dual users, but the rollout should be expanded to a larger audience over the coming days.
