Hopefully your storage problem wasvsolved but in case you still need to then I would
suggest that you use a windows7 laptop or desktop and insert the SD card in its slot
with the SD card adapter and format it 32bit. Then take it out and push it in your tablet.
The SD card should be detected now. I think I had a problem with windows 10 not
giving me the option to format to 32 bit. So I used Windows7 even though its a 64 bit
system. I hope this helps others too. Happy Holidays !
