Some time ago, the default browser would randomly turn on by itself with annoying pop up apps. Porn, wierd badly translated clickbaits,like the stuff that pops up on your computer when you are watching movies online. I tried disabling the browser app, but wierdly enough, the pop ups started appearing on their own. I tried reseting the phone multiple times, deleted all the data, wiped memory stick, internal memory, everything. Still, the trouble keeps persisting. I'm getting quite desperate here, any idea what might work?
