Follow what the app says it will work even without the led light it shows on the bottom.
Doesn't work on Samsung s7 w/7.0
It's working now on my Galaxy J7 Pro. Awesome! Thanks!
Can't turn off the anoyng leds on my Lenovo A6029a40
This app works the best of several I tried. Easy to set up.
✔ Smart Notifications add - Check laboratory functions at the left menu
✔ New layout on screen LED (laboratory function)
✔ App now visible in app history/task manager (stop from battery saving mode)
✔ Many bug fixes and stability improvements
Blue LED since you updated to Samsung 5.1.x/6.x? Enable workaround in app settings at the top!
