Preview, root-only version not working



  • Installed this on a Samsung Galaxy Note II, SGH-T889 and the application does nothing. At first, it would say "starting f.lux", immediately followed by "could not get root access". I uninstalled, rooted the device, and reinstalled. Now, it just says "starting f.lux" repeatedly, but none of the application settings work or change the display on the phone.



  • The preview root-only version is not working for me either! I am trying to install it on a Samsung Galaxy Express Prime and it says the exact same thing to me as it does to you.
