Are you planning to develop Nothing OS 4.1 for all Nothing and CMF by Nothing smartphones, or is it exclusive to the 4a and 4a pro?

Bugs noticed:

While you’re on a call you can’t apply changes to the wallpaper and click DONE. The call status limits the functionality.
Please improve the battery doesn’t feels like 5400 mah on the device. S26 Ultra despite having 5000mah and power hungry chip is optimised crazily for a small size.
