When the Xperia ZL hit the market, and even weeks before the two new Sony smartphones were presented, it came with an application that was used to calibrate the screen, and configure the white balance. The flagship did not have this app. Well, now this application has been ported to the Sony Xperia Z, Xperia T, Xperia V and Xperia TX.
Actually the Sony Xperia Z already had a port that allowed to install the screen calibration application on the smartphone. And it is precisely in this port on which they have been based to create those corresponding to the Sony Xperia T, Sony Xperia V, and Sony Xperia TX, presented above. What is this app for? You've probably compared a Samsung with an AMOLED display with an iPhone with an LCD screen. As you can see, one appears brighter and the other sharper. Furthermore, one has a blueish white, and the other a duller one. Well, this is precisely what we can change with the screen calibration app. We can't choose between an AMOLED or an LCD screen, that's clear, but we can modify the color saturationas well as a tonality, so that we can correct these options.
To install the screen calibration application we will have to follow a few steps. On the one hand, we have to flash the corresponding files in zip folders in the smartphone memory, to install them later from the Recovery. Once this is done, we'll need to place them in their corresponding directory, which varies depending on the smartphone, and then install a "mod" created by a developer. Obviously, it's necessary to be Root. You will find all the information in the XDA Developers forums.

Testing the Touchpad with Android Tools
Before or after calibrating, it's a good idea to check that the touchscreen is working properly. Android offers native functions in the menu. Developer Options which help detect dead zones or poor reading of multiple touches.
To activate this menu, go to Settings > About phone and press 7 times over the build number until the notice appears that you are now a developer. Then go to Developer Options and activate Show heart rate y Pointer locationYou'll see a trace and data at the top indicating the detected points.
The indicator on the left reflects how many contacts the system is reading (for example, X / 10 on 10-point panels). If your device supports 10 points and when you place all your fingers it does not reach that value, there could be a physical limit or software problem.
Move your fingers over the areas where you suspect less sensitivity. If the system requires more pressure or draw a sustained red line If the problem persists, a longer red bar at the top could indicate an affected area. If so, try restarting, clearing your system cache, or contacting support if the problem persists.
Picture Settings and White Balance: Reference Guide
Calibration is not just about white balance. For a balanced image, it is important to adjust gloss, contrast, sharpness y saturationIf you have a test chart (grayscale and color), upload it to your phone or an external monitor for more precise fine-tuning.
Start by disabling factors that alter reading: saving modes ("light sensor»), and processing effects such as noise reduction, smoothing gradations, or temporary detail enhancements. Set the picture mode to a profile Standard and set the backlight to a medium setting to allow for adjustment.
With the card on screen, adjust the gloss until the darkest square is distinguishable from the next one without losing black. Then raise the contrast until the brightest white continues to stand out from the adjacent shade. Avoid raising the sharpness to avoid creating halos around fine lines.
En saturation, seeks to make all gradations visible, paying special attention to the skin tones and the central area of ​​the color scale. If you're working with clean digital sources, keeping noise reduction disabled often results in a more natural image; if desired, moderately activating detail enhancement ("reality creation") or soft gradations can fine-tune the result in complex scenes.
If you connect your phone to a TV or monitor, confirm the actual image size To avoid overscanning: disable automatic display area adjustment and, if available, select "Full pixel». On consoles or PC, choose specific scenes such as Game o Recorders reduces processing and latency.
Calibration on Windows with touchscreen (alternative)
If you also use a computer with a touch screen, Windows includes its own tool. From Start > Control Panel > Hardware and Sound, go into Tablet PC Settings and press Calibrate for touch or pen input, as needed. Complete the on-screen script, accept the changes, and save the settings.
Another fast track is to search Tablet PC Settings from the system search interface (shortcut key) Windows + Q (on supported versions), select the entry type, confirm the User Account Control prompt, and complete the process. When finished, it is recommended Reiniciar to apply calibration to the entire system.
Combining the app cover of white balance For Xperia, touch panel verification on Android and these image adjustment criteria, it is possible to achieve a more faithful and comfortable screen for daily use, games and multimedia content without losing the identity of your device's panel.
