I've recently bought a new SD card with a larger space then my previous one. So it's been week and now my phone is unable to save screenshots or download what'sapp media files. I tried transferring files from internal storage to SD card but it says it's unable to find target pathway. I've tried googling this problem but it hasn't been much of a help. And I'd like to try every other option before I reboot or format my SD card or buy a new one.
