I noticed my drop down bar thing had an advert for "Applock Master" and even worse, at the top, there was a notification icon for texts when I had no new texts.
I held my finger on "applock master" which by the way I had not installed, and it said "Data Traffic Monitor" (I think by TACOTY CN) . I had installed that recently.
I removed it and problem solved.
