With this app, there is a possibility to switch on the notification LED of the Sony Xperia SP, if it is deactivated with the app LED Notifier Off. This app should run on many devices, but due to lack of hardware I can not test this.
With the app Display System Settings, it is possible to test, if the setting "notification_light_pulse" can be changed. If so, this app should do its job.
I use this app to switch on the LED in the morning by using Smart Connect.
