SD card problem , Is there a solution yet?

I have Hi10 plus 4/64 For 2 years. I can’t use it perfectly with such a little remaining storage capacity and SD cards do not appear … Is there a solution yet ??

The only non-temporary solution is to replace the CPU.

I ordered it online from Egypt

What is the best temporary solution?

There is no better temporary solution, everything depends on luck.
You can take drivers from other tablets, install drivers from the list of already installed ones (standard from Microsoft), change the settings in the BIOS, but all this can work for 1 day or not work at all.
