I’ve recently purchased an Alldocube X. I’d like to be able to use an SD card of greater than 128gb so that I can store my FLAC music files on the tablet. I see that the maximum size indicated is 128gb. Has anyone tried using 256gb cards? Not sure if the 128gb is a hardware limitation or just the biggest size confirmed to be compatible by Alldocube. 256gb cards are quite expensive so would rather not buy one until I have some knowledge of whether it is likely to work! Both 128 and 256gb cards are sdxc format, so it should work??
