Why can't I see my Google photos on mobile phone?

[Android Central Question]

I have uploaded all my photos from my laptop, to Google photos to ensure they aren't lost if my computer hard drive dies! I have set up lots of individual albums to enable me to find pics easily.
I can't however see them on my Sony Experia mobile phone or my Samsung tablet when I click on the Google photos app, only those that I have taken actually using my mobile phone or tablet. I have tried searching on the album name, but nothing. I'm not even sure what the process is.......help!

Go to settings, backup and sync, is that checked on? Same email account as the computer?
