@simplex I think that statistics for even Linux desktop users are not too reliable as they generally dislike/distrust #telemetry and tracking, so Linux phone user count could be difficult.
If follower count here on the fediverse is anything to go by, the largest #LinuxPhone-related accounts @pine64, @purism, @postmarketOS appear to have around 13-10k followers. If app download count can give as a hint, the Gnome Calls app (originally made by Purism) was downloaded over 50k times from Flathub https://flathub.org/apps/org.gnome.Calls
As for devices, phones sold with Linux preinstalled include the #Librem5, #LibertyPhone, #PinePhone, #PinePhonePro, #Flx1 and #JollaC2.
Some older Android devices repurposed to install Linux include #OnePlus6, #Pixel3a and #Fairphone5.
