The quality of display of a smartphone or tablet can enhance or mar the level of user experience it gives to its owners. With every release of a new flagship we come to hear about a new screen technology that are often branded by different OEMs as AMOLED (active-matrix organic light-emitting diode), IPS (In-plane switching), LCD (liquid-crystal display) and so on.

Whatever display technology may have used in your device, the quality and color reproduction heavily relies on the matrix structure of 3 main colors RGB (red-blue-green) that combine in various ways to produce the best results. Besides the Red-Green-Blue color dots, there is one more thing that further adds to the color and effects is the Gamma element. Seen under a 400-power microscope, the display of a smartphone like Galaxy S4, HTC One and Nexus 4 might look something like this.


Thus, it is evident that tuning the RGB and Gamma levels on the display might significantly affect the way the display of a device reproduces things. The Nexus 4 is really an amazing smartphone but it is not perfect at all. The phone was launched in November 2012  featuring decent specs and a 4.7-inch screen with a resolution of 1280 x 768 pixel. Since it has been manufactured by LG, it has IPS display that has now become a little older. When compared to the latest generation of flagships that we have now, its screen lacks the vibrancy and saturation of better panels used in devices like the Galaxy S4, HTC One, Xperia Z and Optimus G Pro.

If you own a Nexus 4 and are not happy with its display, it’s time now to revitalize it with better color vibrancy and saturation. The well-known developer Francisco Franco has now come up with a very handy app that lets you play with the levels of RGB and Gamma elements. Thus, it allows you to calibrate the display of your Nexus 4 to suite your eyes. His new app, called Nexus 4 Display Control, lets adjust the IPS screen to achieve the best possible result.


Nexus 4 Display Control app is compatible with all devices with Android 4.2 and higher with root access. It works irrespective of what ROM or Kernel you are using. However, to be able to fine tune Gamma values, your Nexus 4 must have Franco Kernel by the app developer.

Franco’s app can be downloaded from the Google Play for $1.99 which is justified keeping in view the feature it lets you enjoy. The app is also available for free for some time, especially for the users of XDA.

Nexus Display Control (ROOT) Price: $2.99
