SD card issues on Chuwi hi12

Did you format the sd card Fat32 or exfat?

Thanks for your reply Mr. Justinkeyback.

Yes.  I formated a 32 gb sd card to Fat32 and another sd card 64 gb to exfat. Both are not recognizable. First Windows 10 stop recognizing them and afterwards Android also stopped recognizing them.

I think it is a hardware problem because many buyers of Chuwi hi12 reported this problem.

Mine recently started having sdcard problems in both Windows and Android also. I’m suspecting an internal connection issue. For now I’ve just taken the card out.

The same here.  I removed the sd card from the slot.  Surprisingly the device became faster and smoother and very responsive.  The sd card had a very bad effect on the device. This despite the fact that the sd card was of the 10 grade and worked very smoothly on my Galaxy J7 and Lenovo Thinkpad T440s.

I am now confident that the problem is in the hardware and not a software issue.

Back in May, the microsd card slot on my Chuwi Hi 12 operated properly in Win 10 for the first few weeks of ownership but has not functioned since. Tried everything i can think of, for example, different brands of card, capacities, formats, drivers and so on but nothing worked. In Device Manager it reports a fault with the SD Storage Class Controller. Meanwhile, the microsd slot continues to function in Android with no problems at all.

I have scoured the net but there does not seem to be a solution. Several forum threads contained posts stating that this is a common problem with other tablets running Win 10 OS and a firmware update/driver from Chuwi is required. In the end i gave it up as a bad job and use Win 10 without microsd card support. I really hope you find a solution but i fear there may not be one.

I have a 200 GB Sandisk that worked perfectly for a year. Then – out of the blue (in Android) my tablet woke up and “SD Card is blank or unsupported format”. I reinsert the card several times and it is recognized once again, works for my entire tablet session – THEN – upon sitting the tablet down for a bit it is unmounted again. Any ideas? If not, how can I just delete Windows and use the entire Tablet for Android?
