The so-called “better” hardware of the Nothing Phone (2) “Pong” compared to the Nothing Phone (1) “Spacewar” is, in my experience, negligible in daily practice.
The @ronnz98 ROM /e/OS-T e-2.0-t-20240513-UNOFFICIAL-Spacewar has been running flawlessly since the previous versions and the look of the hardware of both Nothing Phones is almost identical.
