Right so I'm currently running AOKP on my S4 i9505 which was running great at first but now it just keeps on hanging, freezing and force closing applications and so I've decided to switch to another ROM. My question is, what is the fastest and most efficient way of backing up all my pictures? I don't want to lose them and I'd prefer it if they were kept in their current respective folders and such, usually the way I'd go about doing this is to back them up into a folder on my laptop but it is taking way too long. Not all of the pictures are on my SD card, I have WhatsApp pictures etc. What can I do?
