The Sony Xperia XZ2's theme engine was one of the best available on Android phones. As part of stock on Marshmallow or Nougat on older Xperia devices, you could theme nearly everything. When the Android Oreo update came, though, many of these older devices lost their theming abilities. Only the wallpapers, accent, and home launcher were able to be themed. That's in comparison to what was previously possible, which was basically the full SystemUI. However, on the Sony Xperia XZ2, Sony brought back this complete theming functionality. Thanks to XDA Recognised Developer/Themer niaboc79, you can now re-activate this lost functionality on older Xperia devices.

The install instructions are different per device, but you can check out the XDA thread below to see if it's supported by your device. Go check it out!
