I have purchased CHUWI Hi10 Plus CWI527, 2 years ago. The tablet does not power on now, the maintenance company told me that the problem is caused by motherboard. when I contacted with Chuwi service with email, they responded as I can choose to send it to Spain for repair or to Hong Kong for repair but when I asked for adress they told me that they have no hi10plus motherboard in stock at present, If I insist on buying from Chuw, they have suggested me to buy on major online shopping platforms by Search Chuwi’s brand and hi10plus’s motherboard. what a shame for Chuwi’s aftersales. Anyone who can help me on this issue?
