The widgets can be applied like any other widget, using any launcher which supports widgets. Long-press on the home screen, or use a pinch gesture to bring out the available options. Select Widgets, and look for the widgets. There are two, you can drag and drop either on your home screen. The transparent widget cannot be changed in any way when it comes to looks, but it can be resized. The one with the background can be changed a bit by increasing the transparency of the background.
To change the widget’s transparency, either tap on it on your home screen or launch the Weather app. Select from the side menu drawer. At the bottom of the Settings page is where you can set the transparency level of the widget. If you want it can be made completely transparent. In the Settings, you can also change the units used to represent the Temperature and Wind speed. It also allows you to decide which information is displayed at which position. Resizing this widget also reveals additional information, since it creates more room.
As you can see above, this Xperia Weather Clock Widget also works with the stock Huawei launcher which means it should also work with any other OEM launcher as well such as Samsung’s launcher. Any other third-party launcher apps such as Nova Launcher or Action Launcher should not have any problems with the widget either.
