Try improve the camera features and stability as well..
Idk about other nothing phones rnn but my nothing phone 3a is having issues like focusing distant objects ain't working properly, sometimes it totally blur out. Also it will be better if the stability is also improved esp when it comes to videography, it kinda glitches in the beginning sometimes so plss luk into that as well.
It will be better if camera performance is also updated with the new nothing os 4.0 .
Adding new animation or customisation to the clock like changing colours acc to the wallpaper, also among the fonts available please add arabic one too in the lockscreen… hoping for the best in the coming stable 4.0 update
