Unfortunately, I have the same problem since long time. And the source problem is not my phone / not my free space on phone / not my internet quality / etc. The menu is acceptable with the speed, but in game it is really very slow performance. I have set the phone performance up to high level, but still the same problem. I can't make some deciding moves (steals, rebounds, blocks). NBA live mobile is really slow and laggy and need a repair with this performance issue. It would be nice if EA support could solve this long term issue. I have invested lots of money and want a good working game. Because I love this game. Thanks!
