The Galaxy Note 7 recall does not affect customers in China as the majority of units shipped to the People's Republic and Hong Kong use ATL's batteries. To be absolutely sure that there are no potentially faulty units in the hands of customers, Samsung has launched an online IMEI check tool through which users can determine if they need to get their unit replaced. The IMEI check tool is only meant for customers in China, Hong Kong and Macau, if you bought your unit from anywhere else it won't be of any help to you.
Those who find that the IMEI number of their device is in the affected IMEI number range can then get in touch with Samsung's authorized re-sellers and distributors to claim their free replacement of the Galaxy Note 7. Customers also have the option to claim a refund for whatever they spent on the Galaxy Note 7 if they are no longer confident about the device and don't wish to use it anymore.
