If LEDs-U-CTRL doesn't work on your Xperia U, don't buy LUC.radar, it will not magically give your XU proper root access.

and if you don't know what all this means.. don't buy it either :)

--- Xperia U with ROOT access only ---
You need a fully functional SuperUser (v3.1.3) with SU binary v3.0+
LEDs U CTRL (LUC) is the ultimate tool to get full control over the LED illumination bar of Sony Xperia U.
LEDs U CTRL combined with LUC.radar lets you use the illumination bar to show notifications for 20 different app alerts in all desired colors.
It enables you to configurate each individual LED light in 1 of 16 colors and use it to notify you for any missed app event alerts.
LEDs U CTRL is the free half of the combination.
You can download this app to see how things work and already create and preview your notifications. You can also use the top half of the Special Features.
