”Yet” ??
I had the OG Jolla as my daily driver circa iPhone 4 era, and it was great experience overall. Running Android apps and whatnot. Eventually the camera and display quality made me stop using it. Still boot it maybe once a year for the fun of it… I think the Sailfish OS did even receive updates till ~2021.
”Pretty fast” after they tuned those automations to the current setting. And they will keep turning it that way unfortunately.
