Hi I have a problem with the Acer Iconia One 7 B1-730HD. Well, I got this tablet, which was purchased in the Netherlands + card MicoSDHC Verbatim 16GB class10, from a friend and i am very rarely able to see this card installed in this tablet and ready to use It is simply not visible in Settings > Memory (as well as ES File Manager File Manager). 16GB MicroSDHC card seems to be fine because it doesn't have any problems when I plug it into a laptop. What I have already tried: 1. format the card in windows 7 (fat32). 2. Format the card with the program SDFormatterv4. 3. Reinstall Android 4.4.2 + download updates (via Settings> Backup & reset> Factory Settings) The tablet does not have any problems with a ScanDisk 2GB MicroSD card ( you can plug it and play - reboot and all). After i have installed 2GB card i can safely remove it and then after i install 16GB card it is visible and useable to next reboot after which it disapears. Can anyone help me how to get to this 16GB card to be always visible in my tablet?
