Ubuntu Touch had been killed by its owner, Canonical, and has been picked up by UBports. UBports is constantly porting Ubuntu to devices. A list of devices can be found at https://devices.ubuntu-touch.io/.
After Canonical announced that they will stop investing in Convergence, the UBports community stepped forward to pick up the development of the Ubuntu Touch operating system. It uses the Mer display server. Applications are being constantly ported to Mer.
