A procedure intended for Android devices, this assessment identifies irregularities in display illumination. It specifically checks for light leakage along the edges or corners of the screen, resulting in uneven brightness. For example, a user might run a diagnostic application or utilize specific display settings to observe a dark image and identify any areas where light is seeping through unexpectedly.
This evaluation is important because it informs device owners or technicians of potential hardware defects or manufacturing flaws that may detract from the viewing experience. Early detection can allow for timely repairs or replacements, preserving optimal visual quality and preventing further degradation of the display over time. Historically, these assessments have become increasingly important with the adoption of high-resolution and edge-to-edge screens, where uniformity is crucial.
