@3T_Ed I don't know if someone is working on UT camera, but GST is a workaround or other option and is working on some Halium 7 ports.
When installing UT on my Oneplus 3T I must have been very lucky, glad got it working. It is not my intention to mess it up for a camera workaround.
I prefer to keep being able to get updates for further improvements rather than taking the chance of getting myself (newbie) into trouble over a camera and not getting updates at all. The OPO 3T works very well considering the fact it's not even an official port. The porting making huge progress though thanks to the work of people like @vince1171 . At the time of installing I was well aware the port isn't ready. Nevertheless I'd love to have a camera option any time soon. It would be a very welcome feature for all newcomers in order to start enjoying their UT.
After all, people new to the UT scene would like to see the essential apps working, going through some psychological process of cognitive dissonance as it is, as to whether they have made the right choice to go the (alternative/"don't-do-it-I-told-you-so") UT route, not having to dig into various procedures - which might seem logical and easy routines to those who are already used to Linux distros and terminal commands - in order to get the basics running.
I hope ultimately UT will become an OS everyone can install in confidence like an out of the box experience. This community is one of the best I have come across, no doubt UT is (going to be) a huge success and if things will be smoothed out many non-Linux users will take the leap of faith to make the switch.
Meanwhile I guess I will just keep things as they are, sticking to the default apps and restricted to installing from Open Store only, eagerly awaiting the release of a camera app.
