I’ve updated sideloading a full OTA with ADB just to avoid any incremental upgrade issue. Everything seems working properly.
The only thing is the display refresh rate in dynamic mode that is set to 120Hz navigating through Nothing OS launcher icons and options, 90Hz using quite almost apps and 60Hz playing full screen videos. Actually I’ve checked this thing because I’ve read previous comments here, maybe there was the same behavior before. Probably 120Hz refresh rate in system interface is a choice to emphasize the Nothing OS smoothness.
