FOSS mobile OS FuriOS has been updated to version 13.0.9 The update includes updates to Gnome, bug fixes, support for two way clipboard, and more. I was able to upgrade my FLX1 from 13.0.8 to 13.0.9 simply with a couple rounds of "sudo apt update" and then "sudo apt upgrade". I had no issues with my upgrade.
