SD Card not mounting after reboot My Android doesn't mount my SD Card after reboot. I need to get out the SD Card slot and put it back in. Can I fix this?

By the way I have a Samsung Galaxy J7 (2017).
Try inserting another SD card in your phone if it does that means there is problem with your SD card

Try opening the same SDcard in your laptop and see if opens copy the data and format...if it doesnt open try formatting it and then insert in your phone
