My pictures transferred to the tablet from my phone. They are in no order, would like to organize them
In your app drawer you should see one. If not, you can download one from Google Play store.
On your tablet, there's a file explorer/manager. In it, touch SD card > DCIM > you create a folder there, these folders that you will create there will show up in the Gallery. Try it! Let me know if that works for you.
