Encountering color fading on a mobile phone can indeed make people anxious, don’t panic for now! The fading of the outer border of iPhone 17 Pro Max is mainly related to defects in the anodizing process. The following are specific solutions:
Root cause
Oxide layer defects: The 7-series aluminum alloy has a high zinc content, thin oxide film, and many pores, which leads to the easy precipitation of dyes.
Sealing process failure: Some batches did not completely seal the pores of the oxide film, and sweat, cleaning agents, and other easily permeable bleach dyes.
Impact of inferior accessories: Using inferior acrylic film or double-sided tape may corrode the oxide layer.
countermeasures
1. Submit a diagnostic report through the Apple support app and select the “Appearance Abnormality – Color Change” option.
2. Keep the IMEI (obtained by entering * # 06 # on the dialing interface) and purchase voucher, and some batches can be replaced for free.
