We provide "three checks" service: 1. Check the purchase receipt, 2. Check the device serial number, and 3. Check the fault video. Non-human damage (such as natural cracking of the glaze and chip failure) is repaired free of charge, and human damage (such as external force impact) is charged at cost.

Submit an application through the "Global Service" portal on the official website. The system automatically identifies the country and assigns a local engineer. It supports settlement in 12 currencies, and accessories are sent through the DHL priority channel.

Routine faults are resolved within 72 hours (including logistics time), and complex problems are provided with phased progress reports. Commercial customers can apply for expedited service (pay an additional 20% service fee).

The official website provides 3D repair manuals and video tutorials, supports customers to replace modular components (such as sensors) by themselves, and core components are recommended to be operated by certified engineers to ensure waterproof performance.

If there is no man-made damage within 15 days after signing for the product, you can apply for a free exchange. If the same type of failure occurs 3 times within 1 year, you can apply for a return. Complete packaging and inspection report must be provided.
