As of now, the 90 fps in game option is successfully available for all Phone (2) models. However, users are still experiencing a glitch. While the in-game 90 fps is unlocked, it appears that the system side is not reflecting this, as the fps meter shows 60. Users have to activate pop-up mode and then return the app to full screen to properly unlock the refresh rate. This seems to be a bug related to the Nothing Team itself. It might be worth investigating further.
