Last year of so my Galaxy S5 has be infested with annoying ads, even at sign in stage. My provider says that these would have been introduced by my downloaded apps, but cannot tell me which apps are responsible. Have been advised to delete "Peet" but although I recognise the name how can I find and then delete it?
Only run a few apps on the mobile; Yahoo Mail, Google, Maps, Navigation, Torchlight, a few Mario, Pokemon and Star Wars themed games. Which is likely to be the culprit?
