@BigMikey i had a phone with ubuntu, Spanish phone maker BQ was selling Ubuntu phones. It was 2018 or 2019... I quickly returned the back to the seller. The project was not very well developed and the phone was not very useful. Not sure if it is more developed now...
@MariusRime that was a very real issue at the time. I have heard it has improved but I have yet to try it for myself.
