I'm using Samsung S Duos 7582. My phone was hanged and i restarted it , after that the pictures in my device storage and SD card is not visible in Gallery. And not able to select the mp3 songs as my ring tone, I've restarted the mobile device many times. But no change , kindly suggest.
I know it's too late to answer this now but I think someone else will find this helpful.
Go to file manager you'll find a folder named
DCIM change its name to
DCIM0 or something like that. Then create a new folder named
DCIM. Reboot. It should be alright after this. You can move the pictures and videos in
DCIM0 back to
DCIM after this if you want.
