Hello,

I'm experiencing lots of problems with the micro sd cards in my Dualboot Chuwi Hi12 tablet.  
        
When I insert the card into the tablet it seems to be detected correctly and initially I can work with the card, but after a few minutes the card vanishes. This happens both in Windows 10 and Android. When this happens in Windows 10 the device manager shows  a failure in one of the SD controllers. When this happens in Android the microsd card disappears from the storage section of the device config. After the fail in both operating systems you cannot access the microsd card and in Android you have to force a power off. I tried to extract and insert the card an this behavior reproduces.

I've tried the microsd card in a PC and it works perfectly. Also I tried to format again with the same results. I've tested with several cards from different brands (SanDisk and Toshiba), sizes (16, 32, 64 and 128) and speed (SDHC, SDXC) and the problem reproduces. Also, I verified the issue exists in two different units of the Dualboot  Chuwi Hi12, so seems a global problem and not something specific to my unit.
        
There are lot of reports about this kind of issue in this Chuwi support forums.

Is Chuwi aware and doing something regarding this problem? Anyone has a solution?

Kind regards.

After the last windows upgrade.
Boot win 10 if i insert sd card I hear insert sound, but i do not see sd card. In peripheral management I have driver error. I tried uninstalling drivers and reinstalling, but it does not work.
In android boot no problem.
