Where are you located? Northern EU? We have a lot from the EU here, but you have to be more specific in some cases.
Carriers in the US add their own bloatware to phone and phones are usually locked to carrier if you buy from carrier and/or affiliate. So problems can differ. Our problems might have no bearing on yours.
Where did you buy your phone? Did you buy new or used? (I had a generic unlocked that was sold all over. The phone was not in English.) How did you get the apps on it? Were they on the phone to begin with? Did you sideload? What apps have you updated or added since the trouble started?
While not necessarily the phone - Sony has run into snags about DRM here with other electronics and CDs.
We have things called "push ads" and other crapware. You can read about those.
It could be another setting on your phone, or someone really wants to track your data. There are apps to help with this.
Why not try again - this time maybe asking for our EU community and giving all the info about the phone.
They're not ads, just unwanted, annoying "features".
I'm in Iceland. The phone was issued from my company. I had the exact same phone before but it never did any of these sort of things so I don't know what's different.
I don't know what sideload means.
I have a standard set of apps I install, nothing too extensive or unusual. The "have to swipe twice to use my phone" thing seems to either come from Facebook or something connected with Facebook. The unused app alerts are coming from some service that has a standard system icon (the blueprint style image of a smartphone), according to a long-press on one of the alerts.
I'm really just getting way too many notifications in general, I've never before had my phone decide to notify me about so many things. Right now I have a "notification" from Twitter, which I never use, to join someone in following someone else. My keyboard was bugging me letting me know that I can set it up when I've not messed with its settings or anything remotely like it since I got the phone. There's always just random annoying notifications. But the "app has not been used" ones are the worst, there's usually a bunch of them when it happens, they happen every day, and I can't figure out how to shut them off (I just took care of those other random two).
