I don’t know why they removed Phone (2) from their official website as if it never existed.
I haven’t seen this on other brands’ websites.
Even Apple and Samsung have spec sheets for their old devices (e.g., iPhone 12 series).
Regarding the experience:
The phone experience reached its peak at NOS 2.6.
After NOS 3.0, it’s been going downhill.
Even now, I face rapid battery drain, even at normal room temperature.
There are still bugs on PongIND (Indian unit). I’m not sure about the global variant, maybe due to the software development team building two versions of the same operating system.
