Christmas Blue: A theme for Xperia™ devices
A clean theme based on Christmas with Blue color accent.
✔ Support from KitKat to latest android devices
✔ No root required
✔ Tablet support
** Sony has changed UI for android 7 on phonebook and contacts, where theme doesn't shows effects. Including the old device which has received Oreo updates don't have the most theme's background support presently.
* In case if your phone doesn't show theme's effect (like-applies only wallpaper, as happens on some phones), then try setting-up any default theme and restart the phone & then apply it, or try the same with re-installation.
NOTE: Some of the theme elements may not work (or look different) for some devices or android versions, for the best support at-least Marshmallow is recommended (or Lollipop 5.1).
For example- Theme's Lock Screen Analog Clock is only supported from Marshmallow or some devices running Lollipop 5.1
