[AC Question]

Hello folks with the knowhow..

On my old S3 the snapchat photos automatically save to an album in photos and every photo that came in via viber and whatsapp also appeared in photos app.
Now i have galaxy A3 and this does not happen. In photos app, If i swipe left to 'device folders' the snapchat album is not there. I can only see snapchat photos & videos in the snapchat app.
Anyone have any ideas what to do?
Also if i want to backup my instagram folders etc to google drive the cloud option is not there for these. Only photos taken with camera.
Any suggestions greatly appreciated. .
