⚖️ Seller Warranty & Marketplace Dispute Conciliation

The warranty should be activated for manufacturing defects not caused by misuse, such as internal electronic failures preventing basic operation (e.g., won't turn on even after charging, Bluetooth doesn't work at all) or structural issues that arose without user intervention, as covered by the seller's warranty and marketplace return policy.
