Hi, recently bought a Nokia 6.1 and am having some issues with the SD card. It's a Dick Smith jobbie, about 2 years old with minimal use. I formatted it when I put it in the phone and was able to save pictures to it (from the camera). However what happens is that after a day or so, the card goes read only and I can no longer use it. Unmounting and remounting seems to fix it, but again only for a day. Plugging it into the computer while it's still in the phone won't let me write to the card. If I pull the card and put it in my SD card reader, I can use the card as normal. I have also tried pulling the card and formatting it on my PC, same issue. The only thing I haven't tried is another SD card.
