Camera from Lock Screen?

Apart from everything that has been mentionned earlier

None of the above works on current /e/OS

you need to toggle a switch in the camera settings

Now that works! Amazing, thanks!

OK, so where should I go ask that this be ticked by default?
This is a normal feature on all smartphones.
/e/OS seems to want to target a “regular user” audience but until camera support gets better, there is no way I can recommend it to anyone: honestly, they’d just hate me.
