Is there any health risk of using duplicate memeory cards of china made for the mobile phones?
Well I assume youre talking about your phone’s health. Using fake -made-in-china- memory cards couldnt really ‘damage’ your phone. If you have a little computer experience, you should look up your phones memroy card settings and download it onto the memroy card ( from youre PC, AFTER YOUVE FORMATTED IT!!! ). That should completely remove the risk.
