Hey guyz i found out something new that will improve system fluidity. I have experienced some frame drops while opening and closing the apps and other translation it was not at all 60 fps then i set my DISPLAY SIZE to LARGER or LARGE nd i think i am getting better results.i am getting smooth animations like nova launcher.well it was in my case so i request u guys to go ahead and try it out see if it is really working for u nd comment.
I am using since day one Smallest width 360 dp instead of 411 dp in Developer options / Drawing to get everything as big as on my previous phones (I have poor vision) and have no problem system fluidity, but I use Nova and FNG.
