Con "nigt clock donate" (0,99€) tienes opción de apagarlos. Hay que seguir unos pasos para que pite:
- If button lights don't turn off, try:
1) Turning your phone's automatic brightness on or off
2) Tap to dim screen, then turn screen off and then on (using the button on your phone) This version turns off button backlights for most, but not all, phones. In particular, some new ICS phones do not allow apps to turn off button backlights. If it doesn't work (with the tips above), just uninstall for a refund. Some phones disable my ability to turn the lights off, and unfortunately there's nothing I can do about that.
A mi en el HOS me va bien, pero a veces después de tocar el brillo para alguna otra cosa hay que rehacer los pasos porque pierde la configuración.
