The LG G6 or whatever it really is keeps on plaguing us with unwanted notifications. There were some from games that I managed to shut off, but others keep coming back, especially from word blitz, chrome, and gmail. I told it to block them but it still keeps happening. Worse, they are accompanied by sound and vibration, interrupting even videos. How do we stop the madness? Some of it's lockscreen and some of it's not.
