Cache won't clear - Xperia Z5

Cache won't clear - Xperia Z5

For some reason the cache in my Xperia Z5 refuses to clear - I click on 'cached data' in 'storage' - it shows me around 5MB cache, & tells me 'this will clear cached data for all apps' - I click 'yes', but when it re-calculates the cache is still there-  it clears just a few KB each time I do this; I've done it twice & it's just gone down to 4.50MB.

I also have that app 'AVG Cleaner' which I also use to clear the cache, but this no longer works either - it still leaves most of the cached data there.

NB: I have no apps open when I'm trying to clear the cache.


I have never had this problem before; can anyone advise please?
