Android 'phone question.
I have a Samsung Galaxy Note 3 'phone.
In general I like it but I am plagued with an advert almost everytime I unlock it. At the bottom of the screen it says 'Ads by Google' and if I click on that it waffles about 'interest based ads' which I can opt out of but that still gives me ads not 'tailored' to me, no option to turn the ads off completely.
I have tried all the apps which block or find and eliminate pop up ads triggered by various apps and have few apps which I use anyway so I don't think any apps are the source.
When I first bought the 'phone I had the problem but managed to switch off the ads completely (I forget how) but they seem to have reappeared after a software update and despite searching every setting I can find I cannot disable the popup ad which occupies the full screen when I unlock the 'phone!
Google searches have not revealed anything of use. Does anybody have any ideas, it is driving me mad!
