• Apple has acknowledged a known issue with hairline cracks appearing on the aluminum bodies of certain iPhone and Apple Watch models. These cracks can develop over time, often due to normal wear and tear, and can compromise the water resistance of the devices.

• To address this problem, Apple has extended the warranty coverage for affected iPhone and Apple Watch models. Customers with devices experiencing these hairline cracks can now get them repaired or replaced free of charge, even if the warranty has expired.

• The article notes that this is not the first time Apple has faced issues with the structural integrity of its devices. In the past, the company has also dealt with problems like "bendgate" with the iPhone 6 and 6 Plus. This latest hairline crack issue highlights the ongoing challenge of balancing sleek design with robust construction in modern smartphones and wearables.
