The Best applications: Adjust the brightness and the color temperature of the display

In recent years, due to increasing use of smartphones, we have started talking about quality of brightness and visual comfort in the use of the devices.

The type of light emission of a smartphone should be adjusted in relation to the illuminance of the environment in which we are. By day and in well-lit environments, our smartphone should have a cold color temperature (4500K 5000K) and high intensity, instead the night should have a warm color temperature (2700K 3000K) and low intensity (in many cases also the minimum value imposed by the manufacturer may be too high).








The LED technology that use the displays of smartphones, allows huge adjustments of luminous intensity and color temperature.
Through these three applications that I am going to recommend, you can make lots of adjustment:

The more professional: Twilight
You can adjust the brightness, the color temperature in degrees K and the intensity of the color filter, and you can select a specific time in which you want to automatically activate the filter, or select your location you will use your sunset times for activate the filter.
You can even use a widget on the system homepage.
