@BrianA @agx @dos @kyle kernel updates are technically feasible (all modules are open source) -- they'll be looked into when and if they show a tangible user-facing benefit (i.e. beyond "number is bigger"), or whenever we have enough free time for them, whichever comes first.

VoLTE is a work in progress and a rather high priority one at that. chances are we'll have it working in the coming 2-3 weeks.

@agx @dos @kyle unfortunately there isn't much we have in that regard. couple examples: a) the kernel we got didn't even have a commit history; b) we couldn't get the datasheet for the display panel.

I'm aware this isn't optimal, but perfect is the enemy of good & we had to start somewhere. if this goes well, we'll probably have better leverage in the future for that sort of stuff.

@agx @dos @kyle I work on this phone. you hit the nail on the head; it is our goal to share and upstream as many of our improvements as possible throughout our shared stack. you may have already seen me around GitLab now and again. :)

re: mainline, afraid it's not in our roadmap. getting the device in a halfway semi-usable state would be a decade-long project and the result would be ~the same to an end user. we prefer to focus our energy on improving the userspace (e.g. GTK perf, Firefox, etc)
