Recently these spam ads have started showing up on my phone from an app calling itself "Suggestions". I never installed this thing itself and I don't see it on the apps list.
It runs periodically throughout the day by itself. Maybe once/hour? Generally when I turn on the phone and unlock, its there. More rarely it pops up in front of the active app if I've been using the phone for a while.
Presumably it tagged along with something else I installed, but I can't recall that it started occurring at a corresponding time with any other app being added.
Generally once I minimize it, it disappears entirely.
Is there a way to identify & remove this?
