Hi,
My problems is that at first the tablet worked fine whit a 64Gb sd, then two week later it stopped working, but only in W10. One day or two later not even in android worked. In windows i can ear the sound of the insertion but dont recognice it anymore. In Android the system know i have a sd (the card icon is displayed in the left uppercorner) but i cant access the sd. The options related to the sd are greyed out. The only thing i can do is safe expulsion. I tried whit another 32Gb card but in windows is completely unstable. In Android i have the same problem as whit the 64gb one. Is driving me crazy how something so basic in a tablet like the SD controler is done in so poor manner. The tablet is very good but this is a big problem.
Sorry for my broken english.
