I used a pinephone as my daily driver for about a month. Importantly, this was 3~4 years ago, things could be better now.
My take at the time: The battery life was bad, the phone was slow, MMS did not work, making a receiving calls was iffy at best.
I really really hope this improves/has improved over time. Android gets more and more difficult to de-google. A linux phone would solve a lot of privacy issues (not all, but some)
Just out of curiosity, what games do you play that dont work on linux?
