This trick worked for me. Go into SETTINGS, then APPS, scroll over to ALL, then scroll through the apps to the actual SETTINGS app. Once opened, there is a setting ticked called "restrictions RTC sychronization alignment, more power"
Un-tick that setting.
Turn on your location services and turn on WIFI/MOBILE LOCATION. Hopefully, you stop receiving the message.
I was getting the message when I received a call, after a call, plugging up to the charger, unplugging from the charger, and every 10 seconds when I turned on WIFI/MOBILE Location. Very irritating.
