ACuriousFellow the developer / maintainers are supporting more devices but must obviously lower security due to lack of hardware support .
Also, their devices are mostly out of date. The most updated devices are four Redmi devices from June. Five of their devices seem untouched since last year. One of their devices is a Nothing Phone. They also support a Realme and Zuk Zuk, whatever those are.
All-in-all, yet another unserious alternative OS hobby project.
What is the opinion on this project by graphene?
Not even sure they've heard of it.
