The Sony Xperia XZ1 and the Xperia XZ1 Compact were the first Sony phones to launch with Android 8.0 Oreo out of the box. Sony was one of the first device makers to start rolling out Android Oreo updates, as the Xperia XZ Premium received its Android Oreo update in October. The Xperia XZ and the Xperia XZs have also received Android Oreo updates. However, Sony’s mid-range smartphone series has been kept waiting up until now. The Xperia XA1 and XA1 Ultra were launched at MWC 2017, while the XA1 Plus was launched in August. Now, Sony has started rolling out the Android Oreo update to all three smartphones.
The build number for the Xperia XA1, Ultra, and the Plus has been moved up from 48.0.A.1.131 (Android 7.0) to version 48.1.A.0.116 (Android 8.0.0). The update includes the February 5, 2018 security patch. Currently, the changelog isn’t known, but users should expect standard Android Oreo features such as notification channels, picture-in-picture mode, smart text selection, notification dots, the AutoFill framework, faster boot times, and more. Sony has stated previously that the Android Oreo update will remove the Night Light feature for the Xperia XA1 series, so the update isn’t entirely beneficial for users.
The Sony Xperia XA1 series has the MediaTek Helio P20 system-on-chip, 3GB/4GB of RAM paired with 32GB/64GB of storage, and a 23MP rear camera. The Xperia XA1 has a 5-inch HD (1280×720) 16:9 IPS display, while the Ultra has a 6-inch Full HD (1920×1080) IPS display, and the Plus has a 5.5-inch Full HD (1920×1080) display.
The Xperia XA1 and the Plus have an 8MP front camera, while the Ultra has a 16MP front camera with OIS. Finally, the Xperia XA1 has a 2300mAh battery, while the Ultra and the Plus feature 2700mAh and 3430mAh batteries respectively.
