I’ve erase everything from the SD card and I used it as an internal storage but everything was really slow and it stopped working, so I reset all. And I was wondering how can I download things (music, pictures, videos) and save it in the SD card without erasing everything again
To save pictures to the SD card, go to your camera app, into settings and enable save to SD card. To save your music to your SD card, take it out of the phone and transfer your music to the SD card. Hope this helps!
