Nope. Card seems fine when formatted in the Android 7 phone. It lets me move those accursed files on my main phone when I swap it back.
As soon as I format it on the main phone, it stops letting me create folders with that name.
What the actual fuck?
The ONLY thing I can think of that makes any semblance of sense is that the old phone just goes "fuck it lol" and formats the card as FAT32. If it does I will fucking scream because I could have saved myself so many problems and useless writes.
