bro they can't push the graphics setting again to extreme, because this also happened with me 1 year before, I used to play smooth + extreme on my galaxy a70 but after I got an update of tdm it reduced to the ultra setting itself. I had given feedback regarding this issue on playstore,nothing happened dude
