LetsGoDigital has discovered that Sony's upcoming smartphones, the Xperia L3, the Xperia XA3, and the Xperia XA3 Ultra will be released operating on versions of Android Oreo. Even more surprising is the detail that the budget-level L3 will use Android 8.1, while the midrange XA3 and XA3 Ultra devices will operate on the slightly older Android 8.0 OS.
