Warranty policy

Every Musttby part carries a 12-month warranty against manufacturing defects, counted from the delivery date on the invoice.

What is covered

• Display defects: dead pixels, lines, abnormal brightness or touch failure not caused by installation.
• Battery defects: capacity below specification, protection-board failure, swelling without physical damage.
• Glass and touch panels: delamination or OCA bubbling under normal storage and installation.
• Tools: functional failure under normal use.

What is not covered

• Damage from installation (punctured flex, torn connectors, cracked glass after fitting).
• Water damage, physical impact or modification of the part.
• Normal wear and consumable life (blades, needles, glue opened for more than 6 months).

How to claim

1. Send the part number, batch code from the carton, quantity affected and a short video showing the fault.
2. We confirm the failure mode — usually within one working day.
3. Settlement: replacement units in your next shipment, credit note, or refund. Your choice.

DOA units reported within 7 days of delivery are replaced in the next shipment without waiting for the return to arrive.
