Group 1: Company Statements - On the launch day of Honor Magic8 RSR and Magic8 Pro Air, Honor's official store warned users to avoid using full-cover lens protectors due to the risk of blocking vent holes, which could lead to speaker noise [1]. - Honor's imaging system expert previously emphasized that lens protectors severely degrade image clarity and contrast, reinforcing the company's stance against their use [3]. - The chief imaging engineer at Honor also recommended against lens protectors, stating that modern smartphones use high-strength glass that does not require additional protection, and that such protectors can negatively affect photo quality and cause speaker noise [6]. Group 2: Technical Explanation - Lens protectors can degrade photo quality due to their thickness and inability to achieve 100% light transmission, resulting in reflections and reduced clarity, akin to shooting through a dirty thick glass [8][10]. - The interference with speaker functionality is attributed to lens protectors potentially blocking vent holes necessary for maintaining pressure balance in the speaker, which can lead to abnormal operation and noise [13].
