Guys i have found how to play 90 fps on Phone (2) !! , so here is how to do it : open game and then start a match in smooth and 90 fps setting and then when in the match do pop up view from full screen for 5 seconds or so and then go back to full screen you will get 90 fps, i tested it , its definitely very smooth but in tdm sometimes the fps spikes down to 70 fps and it lags , its almost stable (in tdm) but it works for tdmās dont know how will it perform in classic matches as I didnāt play yet, battery drain and heating also will be increased significantly and this trick will have to be done every time you turn the game on if you close it, You can now enjoy 90 fps on your Phone (2) in full screen. Thanks me later ! ( it works for me)
Update : 90 fps is working but now 60 fps feels laggy š , also 90 fps does not work good at all in classic not even for 1 match , the device heats up and lags alot , it is fine for tdm and low graphic intensive wow mode maps.
