Q: Why can it only recognize some TF cards whose capacity is smaller than the one in the description?
A: If the systems cannot read the TF card, that might be because the tablet only recognizes some specific kinds of TF card. If only Android can read it and Windows cannot, there must be a problem of BIOS and you need to flash BIOS.
Mine is a Hi10 Pro, bought a couple of months ago from ChuwiDirect. SD Card was not working, contected seller and received a new BIOS. Flashing was painless but, no changes, even with the new BIOS, card is still not working.
