Adaptive brightness is a very useful feature of AIR³ 7.3. It greatly increases autonomy. When the device is exposed to more light, the screen adapts and becomes brighter. When the device receives less light, the screen automatically decreases the brightness and thus reduces power consumption.
However, you can disable this feature (for example if the upper left part of the device, where the light sensor is located) is shaded but there is a lot of light on the screen.
This can be done temporarily or permanently.
Click F1 or F2 (or any of the on-screen brightness widgets) to force the brightness level (higher or lower). This will temporarily disable adaptive brightness. Each click will increase the brightness by 10%. On different events such as start of thermal, end of thermal, … XCTrack is configured (automatic actions) to revert to system setting, so with adaptive brightness enabled.
To remove this adaptive brightness during the whole flight, Go to Android Settings/Display and deactivate “Adaptive brightness”. Set the default brightness level you want to achieve (e.g. 70%). Start XCTrack. The brightness level will start with the default brightness level you set (example 70%). You can change the brightness level during flight by clicking F1 or F2 (or the on-screen brightness widgets) to force a different brightness level. Each click will increase the brightness by 10%. On different events such as start of thermal, end of thermal, … XCTrack is configured to return to the system setting, so with the default brightness level (for example 70%).
