I am unable to delete the photos, received through whatsapp in nokia lumia 510. How can i delete these pics from Nokia lumia 510? When i delete these photos from gallery, these are not deleted and are visible again.
Go to whatsapp, go into the whatsapp conversation. Click on the contact/group on the top. The group/contact information appears with members/status etc. Swipe right to go to media. You can see all the photos/videos. Delete what you don't need.
If you have already deleted them from gallery, then only the thumbnail of the pic should be visible. You can delete that as well.
But if you still see the pics, there is some bug on your phone.
Go to the Microsoft store and download the Files app. This is a file manager application. Use that to browse through the files on both your phone, and your Micro SD card. If you already have the application, then open it and navigate to:
SD card\Pictures\Whatsapp, mark and delete the photos you want to remove from your phone's storage and gallery.
