Clear duplicated photos, I back up to my laptop

[AC Question]

I'm so fed up of having so many duplicated photos, I want to store my photos locally on my nexus6, but only one copy of each, I back all my photos onto my 20" tablet with a 2tb drive, as I use several different cameras, Google is trying to be all things to all people, it doesn't work, please can someone give me clear instructions how to clear on android 6.0.1 ? Pretty please, it's ruining a rather good experience otherwise

I what way are the images duplicated?
Have you made multiple copies of the same files?
Did you take repeated pictures of the same subject?

Hi, the duplicates are replicated by the OS, possibly showing the local image and the backup version also, but it's not every image, it is a known issue for android, someone said to clear the cache and data for the apps, but I'm unsure about deleting the data for the photos app, I've cleared the cache for several apps, even used the android power and down volume option to clear the cache of the phone. I want to disable the backup procedure, but I don't know how to.

Hi, ref no 673277 on this site, but it's for a Samsung with an sd card, or search for "'duplicate' pictures in Google photos"
I just want to remove them, even if I have to switch off the auto back up and destroy the backup photos. I work in IT but I'm not a techie but this is doing my head in :-(
Thanks for helping out ??????
