Why am I getting ads every time I login to my phone

[Android Central Question]

I started getting ads on my home screen every time I unlock my phone, when I go to make a call, check mail......all the things we do every day on our phones. Some have annoying sound tracks and can't be disabled until they run 20-30 seconds. It slows my productivity tremendously! I'm so annoyed I want to boy cot every thing that is advertised. Ads show on my home screen and I have to swipe to get to my apps. The ads revolve 20-30 seconds. The only way to get rid of them is to swipe to my regular home screen and then one will pop up as soon as I tap an app. What's going on? This started around 12-20-17 after I downloaded an Android app for hands free operation of the phone. It turned out to be a map app too which I didn't need so I uninstalled it but the ads remain.

The phone is a Galaxy S8

Welcome to the forums! It's good that you uninstalled the app, as it sounds like that was the culprit. If you have all of your important data backed up, perhaps consider a factory reset to see if the ads remain.

Thank you. I'm not sure about my backup. Since I got this phone, my contacts have not been syncing with google. I think it was initially set up to use Samsung contacts. I switched it to Google contacts as default but still am not seeing new contacts added to the phone show up on my computer (google contacts) or vice versa. Have had "Galaxy expert" work on it and that resulted in triple and quadruple contact entries but still no sync. My contacts are a mess and the merge contacts feature doesn't work to clean it up. Now the ads. I can't even make a call without an ad I have to get rid of coming up. This used to be limited to games until you paid for ad free versions. Could this part of the new deregulation legislation showing up already? Any ideas about my contact sync problem. Sorry, I should have posted in the S8 forum. Perhaps I should post this problem there?
