I tried a 64GB and 32GB card in my Hi8 pro, and samething. It will say blank or unsupported media. If I go to settings-> storage, I can’t mount the SD card in Android 5.1. Win 10 also can’t see the sdcard.
However, both cards work in my older Hi8.
I updated to the May bios following this: http://forum.chuwi.com/forum.php?mod=viewthread&tid=1157&extra=page%3D1&page=1&mobile=2. But doesn’t help….
Any ideas?
