23.4.2018, around 12:34... I realized how unix ttys are sabotaging my attempts to send SMS.. and solved it. So now I have Motorola Droid 4, running 4.17-rc1 kernel, with voice calls working, SMSes, data connection, GPS working and have some basic GUIs to control the stuff. WIFI works. Screen locks, and keyboard map still could be improved. Battery life will probably will not be great. But hey, its a start -- I have GNU/Linux working on a cellphone. More precisely Maemo Leste, based on Devuan, based on Debian. Sure, some kernel patches are still needed, and there's a lot more work to do in userland... Today, Microsoft sold out last Windows Mobile phones. I guess that's just a coincidence.
