I've tried this and it hasn't helped. PLEASE help me with this as I am SO frustrated! I've never had this problem before. One morning I woke up and it started doing it and it's awful!
Im having this issue on my new galaxy S8+. Friends tried to help but still being driven crazy with unwanted pop up ads. I cant even controol my phone when i try to call ads pop up all over the screen i cant click or call or close it for over 10 sec what if i were in emergency situation. and what pissing me off those ads comes randomly.
I've been happily using iphone for more than 5 years and i never had to face or complain for any malfunction like this im frustrated from your weak system.
Sumsong i will ad blocke you from my life if you dont fix this soon.
