I am using a 128GB micro sd card on my android phone, and i recently noticed that i could not write any files to it. Reading works fine.
I tried to format it using my windows computer, without success. Every file i remove reappears when i replug the micro sd in.
I tried following the steps in this guide, with no success.
Do you have any idea on what i should do ? Please let me know in the comments if you need anything else.
