The LD MicroSD 128GB card from “LD Official Flash Memory Store” on Aliexpress when formatted as fat32 works with the Teclast X98 Pro in Windows 10 mode only.
When I first received it, it was formatted as exfat. This did not work under Windows 10, nor Android. Android’s Setting’s Storage listing reports no MicroSD card inserted.
I then inserted the card into my laptop, downloaded fat32format (guiformat.exe) and quick formatted as fat32. Reinserted into my X98 Pro. Checked both OS and still nothing. Android’s Setting’s Storage listing still reports no MicroSD card inserted. However under Windows 10 I checked Device Manager and it was there! However, something was stopping it from initialising. After quickly googling it, it seems you need to do a non-quick format. So, microSD card back into laptop, reopen guiformat, untick quick format and Start. It got to like 5% and hung (I presume overheated the card – it was HOT!!!) so I clicked Stop, which then makes the app reformat the card again as fat32 quickly. Reinserted into X98 Pro and it works!! Android’s Setting’s Storage listing still reports no MicroSD card inserted.
TLDR;
Bought a 128GB LD Micro SD Card
Used a different PC: Fat32Format, untick Quick Format, click Start, process reaches ~5% and hangs, click Stop, program automatically quick formats
Insert card into X98 Pro. Windows YAY! Android NEY.
EDIT: The LD SDXC MicroSD card has stopped working in the tablet. Have tried formatting it (in a different computer) repeatedly as different formats, to no avail. :'(
