Also what works as I discovered, is if you go into "Display", then "Display Themes"...then make sure the phone is not set to "default", but "Blue, Business or Tropical" (I have my phone set to Tropical)...when you turn the phone off then on, the settings in "Sound" will continue to remain and the blue light's will continue to function every time! 🙂 And you won't have to go through the hassel of plugging in the charger each time to make them work again. But I also hope they get the software upgrade soon to permanently fix this...for this is really only a temporary fix. Try it...hope it works for you too! 😁
