HTC Malaysia offers 2 years warranty (1 + 1 year extended warranty) for all HTC Smartphones purchased from HTC authorised distributors like SiS Distribution (M) Sdn Bhd and Brightstar Distribution Sdn Bhd. You still can enjoy 1 year extended warranty if you don’t register it online. But the extended warranty coverage will be started based on the HTC manufacturer shipment date which is earlier than your HTC phone purchased date. So better register it online for extended warranty and do so within 7 days after purchased.
