Lumia 640 XL UUUUUUUU.uuu

[Pablo Rocha]

First that my phone don't accept install my apps at my MicroSD.

Second that I format the SD from the mobile and when I open the card from my PC I have a lot of folders named UUUUUUUU.uuu.

I've tried format from my PC but nothing changed, when I copy the files all the folders are created again.

Did you try formatting your sd card with quick format unchecked.

I have the same issue with my 640XL and I also had it when I bought my 535.... In my case there isn't any UUUUUU.uuu folder but the devices wouldn't install apps or accept anything into the SD Cards that I bought and they keep corrupting the SD Cards until it will be destroyed and unusable.

But did you fix that or do you still with those problems?
