The famous Japanese operator NTT DoCoMo has published a list of Sony smartphones that will receive an upgrade to Android 10. There are six models with global registration and one local one in a small list.
So, according to the Android 10 operator, the following Sony smartphones will receive: Xperia XZ2, XZ2 Compact, XZ2 Premium, Xperia XZ3, Xperia 1 and Xperia 5, as well as Xperia Ace – this is a local version of Xperia XZ4 Compact. Unfortunately, the flagships of 2017 Xperia XZ1 and XZ1 Compact are not listed. These models came out with Android 8.0, but were subsequently updated to Android 9.0 Pie – they will remain with this version of the OS. Xperia 10 with Xperia 10 Plus is also not mentioned, but they simply are not sold by the operator, so they are not on the list.
